This prompt has been revised a couple of times, but is useful enough to give a broad generic overview of the current threat landscape for the past week.
I set it up to trigger every Friday morning at 7AM and to email and notify me in the Grok app, that way it is sitting in my inbox ready for a nice easy start to my Friday morning with a wee cup of coffee before I start my day.
Its a pretty great starting prompt to then customise and configure how you like it, to insert your businesses own requirements, manufacturers you use, or technologies you wish to pay special attention too. By no means comprehensive, but for me has replaced my RSS reader alongside a similar daily task in Perplexity pro.
Anyway, here it is, simply copy/paste the below md into the task section on Grok, and set your scheduling requirements as needed,

AI, especially autonomous AI is inherently dangerous. Yes it’s virtual, but let’s just pretend that it has the same sort of risk profile as driving a vehicle.
Would you let a 14 year old teen loose in a semi-truck? A JCB? How about the family car? Probably not. Would you let them drive the family car about in a non-public field for a bit of fun? Maybe, but that would be your decision as a parent.
How about you – I’m guessing that most people reading this have a drivers license, and If you are in the UK (like me) or EU, you drive a manual (stick shift).
Would you yourself, on a public, busy, peak traffic time B-road (country byways) allow yourself to drive an articulated airport style bendy bus? How about a bendy bus packed with 60 random members of the public? How about trust yourself to put it into Autopilot mode and program it to drive both you and your passengers?
Probably not.
You have probably guessed what I’m getting at. For anyone missing the link, this is the exact analogy for AI models, autonomous agents, and your clients’ data.
Replace the vehicle with autonomous agentic AI.
Conscious decisions, laws, rules, regulations, insurance and licensing controls contain drivers in an agreed upon manner keeping us mostly safe and sound out there on the roads, and recuperating losses should and when anything does go wrong (accidentally, due to negligence, or deliberately).
At the very least, autonomous agentic AI must be licensed.
We can’t ship autonomous agents that touch real money because the liability exposure is infinite. We don’t need a pause; we need a valid Chain of Custody.
This is a proposal for an AI “Driver’s License”: “Junior devs” work in sandboxes, while “Principal Operators” cryptographically sign off on production deployments under a corporate fleet permit. This unlocks insurance markets and “Unshackled” Tier 3 models.
A user- or worse, you – are noticing a strange system behaviour. The classic is a flashing “waiting” cursor, a “blip” every second, or a Task Manager window that seems to be constantly refreshing.
The Quick Fix TLDR:
Check the basics first:
Task Manager check for basic High RAM, CPU, Memory apps.
Check Event Viewer for obvious spam from a specific app.
Check for Updates to see if anything is queued or recently (since issue) been updated.
Pending reboots that might be causing a service to fail.
Check Drivers: ensure all main drivers (GPU, chipset, network) are current.
Ask AI: take a screenshot or screen video and upload itwith the issue, and what your step 1 found.
In this case:
Use ProcExp.exe
If nothing obvious appears, move onto ProcMon.exe
Use AI as a filter helper
It knows the filters and syntax better than you. (unless you use these tools alot…)
Done.
Your first move? You open Task Manager. And you see… nothing. No app is hogging the CPU, memory is fine, and the disk is idle.
The problem lies in the fact that Task Manager is a dashboard. It’s great for seeing what’s currently running and what’s using resources. It is terrible for catching a process that starts, runs for 100 milliseconds, and then terminates. It’s born and dies in the blink of an eye, never troubling the dashboard’s refresh cycle.
When Task Manager fails, you need to bring out the right tools. For GUI-loving admins, that means the Sysinternals Suite. This guide will show you how to use two of its most powerful tools- Process Explorer and Process Monitor- to catch that “ghost” process.
Our Case Study: The Mysterious Flashing Cursor
This tutorial isn’t just theory. This exact method is how I solved a maddening problem on my own Windows 11 machine:
The Symptom: For 5-10 minutes at a time, my mouse cursor would flash the “waiting” icon every single second.
The Investigation: Task Manager showed absolutely nothing. Ending common apps like my browser or screenshot tool did nothing.
The Cause: A “ghost” process was launching and terminating, over and over.
Phase 1: The Standard Sysadmin Checks
Before diving into heavy tools, every admin should run through the “quick fix” checklist. Sometimes the solution is simpler than you think. My first steps were:
Check Event Viewer: I looked through the System and Application logs. I saw a few DNS-related entries from earlier, but nothing critical and nothing that matched the timing of the flashing cursor.
Check for Updates: I manually ran Windows Update to check for pending updates or, more importantly, a pending reboot that might be causing a service to fail. The system was fully up to date.
Check Drivers: I ensured all my main drivers (GPU, chipset, network) were current.
With these simple checks ruled out, I knew this was a deeper issue.
Phase 2: Identifying the Type of Problem
My core symptom- the flashing cursor- told me how the problem was behaving. It wasn’t a hung app or a memory leak. The rhythmic, once-per-second “blip” was a classic sign of a process loop. Something was trying to start, failing instantly, and then trying again, over and over.
This is where the modern troubleshooting toolkit comes in. Traditionally, I would have had to just know this from experience, like I did; but today, this is a perfect task for an AI assistant.
A junior engineer could have taken a 15-second screen recording (like the one above) and uploaded it to an AI like Gemini.
"I've got an intermittent flashing 'waiting' cursor on Windows 11 (see attached). It's not a high-CPU process; Task Manager is clean. I've already restarted explorer and other common apps. I suspect it's a process starting and stopping too fast to see. What's the best way to catch it, which logs should we look at first, or which tools should we spin up?"
The multimodal understanding of these tools is strong enough to analyse the video and suggest,
"The rhythmic flashing of your cursor, combined with a quiet Task Manager, strongly suggests a rapid process loop."
The AI is a tool, just like procmon. Using it here saved me from guessing and allowed me to move straight to the right tools for catching a process loop.
Tool 1: Process Explorer (The Live View)
Your first step up from Task Manager is Process Explorer (procexp). Think of it as Task Manager’s brilliant, all-knowing older brother. It’s a free, standalone GUI tool from Microsoft.
For catching fast-moving processes, procexp has one killer feature: Difference Highlighting.
How to Use It:
In Process Explorer, click on Options in the top menu.
Go to Difference Highlight Duration…
The default is 1 second. Change this to 3 or 5 seconds.
Now, just watch the main process list.
Processes that are newly created will flash bright green.
Processes that have just terminated will flash bright red.
For many “ghost” processes, this is all you need. You’ll see a process name flash green, then red, over and over. You’ve found your culprit.
In my case, the loop was so fast that this was just a blur of red and green flashes. It confirmed my theory but didn’t clearly identify the process. It was time to bring in the “CCTV.”
What If You Can See the Ghost Process?
Let’s say the highlighting does show you a process, but it’s still hard to pin down. Here are two more ProcExp tricks:
Sort by Start Time: Right-click the column headers (like ‘CPU’), choose Select Columns…, go to the Process Performance tab, and check Start Time. Now, click this new column. Your looping process will repeatedly jump to the top of the list as it’s created.
Check Command Line: Once you spot the process, right-click it and go to Properties…. The Image tab will show you the full Command line path. This is vital. A process named svchost.exe is meaningless, but seeing its command line might show you it’s running a specific, problematic service.
Tool 2: Process Monitor (The “CCTV” Log)
If Process Explorer is the live video feed, Process Monitor (procmon) is the high-definition, frame-by-frame “CCTV” recording of everything happening on your system. It logs every file read, every registry key access, and- most importantly for us- every process creation.
Running it with no filter is like drinking from a firehose. You’ll get millions of events in seconds. The key is to apply a filter.
How to Use It (Step-by-Step):
This is the definitive, 60-second method to find your “ghost” process.
Run procmon.exe as an administrator. It will immediately start capturing.
Stop the Capture: Click the Magnifying Glass icon in the toolbar to stop the flood of data (or press Ctrl+E).
Clear the Log: Click the Eraser icon to clear the events captured so far (or press Ctrl+X).
Set the Filter: Click the Filter icon (the funnel) in the toolbar (or press Ctrl+L).
In the filter window, create the following rule:
OperationisProcess Create
Click the Add button. The rule will appear in the list.
Click Apply, then OK.
Set One More Vital Option: Go to the Filter menu and make sure Drop Filtered Events is checked. This is crucial. It tells procmon to immediately discard any data that doesn’t match your filter. Without this, procmon will still log millions of events in the background, consuming all your memory.
Start the Capture: Click the Magnifying Glass icon again (Ctrl+E) to start capturing.
Now, wait for your “blip” or flashing cursor to happen. Instead of a million-line log, your procmon window will be a clean, simple list of only the processes being created.
The Result: Finding Our Culprit
In my case, the moment the flashing cursor started, my procmon log filled up with the exact same entry, once per second:
rundll32.exe: A generic Windows program used to run functions from a DLL.
davclnt.dll: This is the Windows WebClient service. It’s used to connect to WebDAV (HTTP-based) network shares.
The rest: It was trying (and failing) to connect to my NAS, to set a cookie for the Multimedia folder.
This kind of WebDAV call can be triggered by many things. It’s often an application trying to access a network path that has become unavailable. Common culprits include media servers like Plex, Jellyfin, Sonarr, or Radarr trying to scan a library. It can also be caused by modern WebView2 apps or even Microsoft 365 services that have a ‘pinned’ or ‘recent link’ to a file on that network share.
A Pro Tip: Don’t Ignore the Logs!
Here’s the “lesson learned” part. After I found the culprit, I remembered seeing emails from my NAS. I had set up QuLog Center notifications on my QNAP, and sure enough, my inbox had warnings I had muted for “later.”
They all said: [QuLog Center] Failed to log in. User: X Source IP: x.x.x.x Connection type: SAMBA.
If I had put two and two together earlier, I would have known exactly where to look.
From Clue to Solution (Connecting the Dots)
The procmon clue was davclnt.dll. My immediate question was, “Why is my PC using WebDAV to connect to my NAS? It should be using SMB or NFS.”
This is where my AI co-pilot became essential again. I presented it with the two clues:
"I've got this process spamming, and my server is blocking it but I still have access? What is going on here if everything works as it should and SMB functions?
My PC is spamming davclnt.dll process 'creates'.
My NAS is logging "Failed to log in" via SMB."
This is a deep-cut, “textbook” knowledge problem. As I explained in my companion post on AI-assisted troubleshooting, the AI provided the answer instantly. This is a classic (and obscure) Windows behavior. When a primary SMB connection to a network share fails, Windows will sometimes try to “help” by falling back to the WebDAV protocol.
This one piece of information connected everything.
The Root Cause:
A few days earlier, I had updated the SMB service implementation version on my NAS (not the full firmware).
My PC’s saved, cached credential in Windows Credential Manager was now stale, and the NAS was rejecting it (the SMB failure log).
This “SMB fail” triggered the “WebDAV fallback” loop (the davclnt.dll spam).
The problem wasn’t obvious because my main way of accessing the NAS, the Qsync client, runs over HTTPS and was working perfectly. I had no other symptoms.
The [SOLVED] Fix:
I opened Windows Credential Manager (just search it in the Start Menu).
I went to Windows Credentials.
I found the saved, stale credential for my NAS (NAS-Primary).
I clicked it and selected Remove.
The instant I removed it, the procmon log stopped, and the flashing cursor was gone. I browsed to the share again in Explorer, typed my password, and a new, valid credential was saved.
Problem solved.
Conclusion: Your New GUI Troubleshooting Toolkit
Task Manager is great, but it has its limits. When you’re hunting a “ghost” process, you need to upgrade your toolkit. The modern sysadmin’s GUI-first toolkit for this kind of problem is a powerful trio:
Task Manager: The “dashboard” (what’s happening now).
Process Explorer: The “live video feed” (who is coming and going).
Process Monitor: The “CCTV log” (what exactly happened, when, and why).
An AI Assistant (like Gemini): The “expert in the room” (to analyze symptoms and connect the dots).
For any sysadmin who prefers a powerful, GUI-first approach to troubleshooting, these tools are indispensable.

What desktop UI does Ubuntu 24.04 use? And why are people still fighting about it in 2026?
If you’ve installed Ubuntu 24.04 LTS (Noble Numbat) recently, you might have noticed something: it looks incredibly polished, but also… kinda rigid?
That’s GNOME 46.
On the other side of the fence, you have users posting screenshots of their desktops that look like the flight deck of a spaceship, dripping with blur effects and neon.
That’s usually KDE Plasma.
In this post, I’m digging into why these two desktop environments look so different, the history behind the “war,” and which one actually makes sense for you (or your users).
TL;DR
Ubuntu 24.04 uses GNOME by default. It’s designed to be an “appliance” – stable, distraction-free, and hard to break.
KDE Plasma is the “enthusiast” choice (and what the Steam Deck uses). It offers total control and flashy visuals but can be overwhelming.
The difference isn’t lack of talent; it’s a difference in philosophy (Constraint vs. Agency).
The Philosophy Gap: Appliance vs. Cockpit
The reason the GNOME website (and desktop) looks “boring” compared to KDE’s “amazing” marketing isn’t an accident. It’s a deliberate design choice.
GNOME is an Appliance. Think of it like a microwave or an iPhone. You don’t want to re-wire the control panel of your microwave; you just want to heat your lunch. GNOME follows a philosophy of “Intentional Constraint.”
They remove settings to prevent you from breaking things.
They hide complexities to keep you focused on work.
The Vibe: Minimalist, Zen, Enterprise.
KDE Plasma is a Cockpit. Think of it like a fighter jet or a gaming PC. If you want to move the “Start” button to the top-right corner and make it transparent pink, KDE says, “Go ahead.” It prioritizes “User Agency.”
They expose every setting imaginable.
They embrace modern trends like blur, glass, and shadows.
The Vibe: High-tech, Cyberpunk, Power User.
A Brief History of the Desktop Wars
It wasn’t always just these two. The Linux desktop has gone through several “eras” of dominance.
1. The Golden Age (2002-2008): GNOME 2 Back in the day, GNOME 2 was the king. It was stable, efficient, and everyone loved it. It was the Windows XP of Linux.
2. The Great Schism (2011-2017): Unity & GNOME 3 This is where things got spicy. GNOME 3 launched and radically changed the interface (removing the taskbar, adding the “Activities” overview). Users hated it. Canonical (Ubuntu) famously said “No thanks” and built Unity – their own interface designed for “convergence” (one OS for phone and desktop).
In my humble opinion: Unity was ahead of its time. The side dock and HUD/glass feel were brilliant, but the community fragmentation was rubbish.
3. The Modern Duopoly (2024-Present) Ubuntu eventually dropped Unity and returned to GNOME, but they heavily customized it (giving us the Ubuntu Dock we have today). Meanwhile, Valve chose KDE Plasma for the Steam Deck, proving that Linux could be a consumer-grade gaming platform.
Which One Should You Choose?
If you are a SysAdmin deploying workstations for 50 employees? Stick with GNOME (Ubuntu Default).
Why: It’s predictable. You don’t want Bob from Accounting accidentally deleting his taskbar or changing his system font to Wingdings. GNOME is designed to “get out of the way.”
If you are a tinkerer, a gamer, or someone who misses the “Windows XP” layout? Install KDE Plasma (Kubuntu).
Why: It feels faster (even if it isn’t always) because of the animations. It respects your desire to customise.
How to switch on Ubuntu: If you want to see the difference without reinstalling, just open a terminal:
# To get the KDE FULL experience
sudo apt-get install kubuntu-desktop
# For basic KDE, no presets or tools
sudo apt-get install plasma-desktop --no-install-recommends
# To get the vanilla GNOME experience
sudo apt-get install ubuntu-desktop
# Then to fix it in place reboot to awaken your chosen Desktop Enviroment
sudo reboot
The reality?
Ubuntu uses GNOME because Canonical sells to the Enterprise, and Enterprise loves stability. KDE looks “better” because it’s selling to You, the user.
Personally? I respect GNOME’s discipline, and until recently I ran KDE on my personal rigs when a desktop GUI was needed, simply because I like my buttons exactly where I want them. However I have now grown older and maybe even a tiny bit wiser, and simply go with the flow now, using whatever my distro has selected as the integrated desktop environment for that release.
I have far fewer headaches, and its some extra time saved from customising when really I don’t interact with it all that much (CLI guy & Windows daily driver…).
My honest opinion: If you have time, do what looks best to you, else, stick to defaults. Defaults are defaults for a reason, and have much better official AND community support.

Windows 365 Switch Frozen? Here’s How to Escape a Locked Cloud PC Session
The Quick Fix TLDR:
Minimize Everything: Press Win + Home. (If you can. Or try Win + End)
This minimizes all inactive windows. You won’t see it happen because the screen is frozen, but it forces the local OS to shift focus.
Open Run: Press Win + R.
Launch Terminal Blindly: Type wt (or cmd) and press Ctrl + Shift + Enter (to run as Admin).
Accept UAC: Press Left Arrow, then Enter.
(This blindly accepts the “Yes” on the User Account Control prompt).
Kill Explorer: Type the following and hit Enter:DOStaskkill /f /im explorer.exe
(Optional) If explorer.exe did not auto restart type the following and hit Enter: explorer.exe
Your screen should blink black as the local Windows shell is killed, taking the frozen RDP session and Taskview with it and then should automatically restart. Done.
It is the stuff of nightmares.
You are happily using the shiny new Windows 365 (task) Switch feature, bouncing between your local desktop and your Win365 Cloud PC seamlessly via Task View (Win + Tab) – when suddenly, everything stops.
The remote session freezes. But because Switch integrates so deeply with the local Win11 OS, it doesn’t just hang the window; it deadlocks your entire local PC.
The mouse moves, but you can’t click anything.
The Start menu won’t open. Alt + Tab does nothing. You are effectively locked out of your physical machine by the virtual one.
I found myself in this exact jam recently. The screen was frozen solid, and I was seconds away from a hard reboot when I managed to find a “blind” escape route.
Here is the quick fix if you are stuck right now, followed by why it happens and how to stop it coming back.
The “Proper” Escape Routes
While killing Explorer is effective, it is a bit like using a sledgehammer to crack a nut. If you have the presence of mind (and a responding keyboard), there are cleaner ways to get out.
I’ve listed these from best to worst:
Options:
Command
What it does
Rank
The Clean Break
tsdiscon
Best Option. It tells the Terminal Services client to disconnect immediately. It leaves your Cloud PC running in the background but drops you straight back to your local desktop.
1
The Interrupt
Ctrl + Alt + End
This is the RDP version of Ctrl + Alt + Del. It sends the interrupt to the remote PC, which often jars the local session enough to break the input deadlock.
2
The Sledgehammer
taskkill /f /im explorer.exe
As detailed above. It kills the local shell. Messy, but it works when nothing else will.
Tries to escape to your Host PC, opens an elevated terminal or CMD, then kills explorer.exe and all associated hooks and processes – that are hopefully causing you to hang.
(1) 4
Why Does This Happen?
Windows 365 Switch isn’t just a standard app; it hooks right into the Windows 11 shell to act as a native desktop.
When the RDP protocol flakes and has a radge, it is usually due to a network spike or a graphics rendering loop while in full-screen. It refuses to let go of the display and input hooks. Meaning you are left with local explorer.exe waiting for the RDP process to say “ready,” but the RDP process is aff tae the shaps. Result? Total deadlock.
Prevention is Better than Cure
In reality, but I’d rather not have to type blind commands to use my own PC, or have type blind commands anywhere really!
If you are an admin (fingers crossed if you are reading this, you are), you can push some Intune policies to stop this happening across your just your PC (selfish much!), or out to the entire Intune estate. It comes down to telling the RDP client to prioritize local stability over fancy remote graphics, and for now – seems to do the trick.
I’ve drafted a separate guide on exactly which settings to change in Intune to keep your Cloud PCs stable, will be placed in the link below soon!
