Windows 11 25H2 – Update KB506881 causes unexpected reboots (no BSOD, silent restart)
Hey everyone, just wanted to report a serious issue I encountered with Windows 11 25H2 related to the update KB506881. After installing KB506881 my PC randomly rebooted without warning — no BSOD, no crash report, no error on screen. Only the event log showed “unexpected shutdown / Kernel-Power (Event ID 41)”. Removing the update completely solved the issue. Since uninstalling it, my system has been 100% stable with zero unexpected restarts. Reproducibility: Install KB506881 → system performs unexpected shutdowns / reboots Uninstall KB506881 → issue disappears immediately System details: Windows 11 25H2 (Build: 26200) AMD Ryzen 7800X3D (but issue seems unrelated to hardware) No BSOD / no memory dump / no bugcheck created Reliability Monitor only shows “Unexpected Shutdown” What I already did: Removed KB506881 manually → issue gone Blocked the update using PowerShell + scheduled task (hourly) to prevent Windows from reinstalling it Logs: Event Viewer → Windows Logs → System Shows: Kernel-Power 41 (unexpected shutdown) immediately after KB506881 installation. Has anyone else experienced unexpected reboots after KB506881? If yes, please comment so Microsoft can see how widespread this is. I also reported it via Microsoft Feedback Hub. Thanks!
Windows 11 not updating to Windows 11 Insider Preview Feature Update (26220.7051)
Respected Madams/Sirs, I am facing a very unexpected problem while updating to Windows 11 Insider Preview Feature Update (26220.7051), which encounters an error and says, "couldn't extend system reserved partition". My disk has a lot of free space available, but the EFI, of course, was full with 6mb left, so I had to extend its capacity. To fix this, I tried numerous methods, but they eventually proved fruitless. Tried extending the EFI size (currently 100 MB) using GParted, but couldn't, so created a new EFI with a 500 MB size. Executed the necessary steps and commands to make sure the computer used the new EFI as its primary EFI. The computer boots using the new EFI, but the update error hasn't gone. Tried clearing unnecessary files from the original EFI. Nothing worked. Tried cleaning my hard disk, which of course might not be the key for this since the error is related to EFI, not the hard disk itself. Still, nothing worked. To put it short, I may have tried every method possible, but nothing has worked. I urgently require assistance. My current Windows version is Windows 11 Home, version 24H2, OS build is 26120.6982, on a Dell Inspiron Laptop Please help. Thanks!
Windows 11 Insider Update error
We couldn't connect to the update service. We'll try again later, or you can check now. If it still doesn't work, make sure you're connected to the Internet. I am running Windows 11 Pro 24H2 enrolled to Windows Insider release preview. I am getting the error message which I provided ahead. I reached out Widnows technical chat support, they referred me here as they do not support Windows 11 insider build. They performed sfc/dism, restarted windows update service, I downloaded Windows 11 ISO 25H2 but the option keep files and programs is greyed out as I am running Insider build and I wanted to keep my files and programs too. Please provide fixes for my version now.
Advanced Startup Cannot Navigate, No Cursor After Updates
After recent Windows updates, when I went in to Advanced Startup to run Troubleshoot, my cursor was missing and the keyboard arrow buttons didn't even work! Unable to navigate in the there at all. Is there a Fix for this? The only way to escape the page is to hold down the Power button on Tower! It's annoying. On the Advanced Startup blue screen (not bluescreen BOD!). Here's a thread on the topic I'm not the only one! https://www.reddit.com/r/pchelp/comments/1o6xxpf/windows_11_advanced_startup_not_working/ Thanks.Kikero – Proposal for Windows 11/26H1: Fixed 4GB System RAM Limit for Maximum Performance

Project Diamond is a proposal for what Windows 12 should become: a fast, clean, and modern operating system that finally unleashes the full potential of today’s hardware. The goal is to bring back the speed of Windows 8, the practicality of Windows 7, and add modern features—without the bloat that slowed down Windows 10 and 11. Core Pillars of Project Diamond 1. Speed like Windows 8 • True instant boot in ~2 seconds, without relying on BIOS/UEFI Fast Boot tricks. • Only essential services load at startup—no unnecessary background tasks. • Hardware performance (SSD, NVMe, modern CPUs) fully utilized. Clean UX/UI • A consistent environment—no more mixing old Control Panels with new Settings. • A Start menu that blends the practicality of Windows 7/8.1 with modern features (search, pinned apps, AI suggestions). • Minimal animations—snappy response first, eye candy second. • Tablet mode as an option, not a forced default. AI—integrated but safe • Copilot and other AI features run in a sandboxed environment, isolated from the OS core. • Prevents viruses or manipulation from spreading through AI processes. • AI acts as a helpful assistant, not a system bottleneck. Graphics and DirectX • Optimized DirectX API with less overhead and better GPU utilization. • Reduced UI animations to free resources for apps and games. • Flexibility for developers to leverage DirectX 12 or Vulkan where appropriate. Stability and Security • System apps sandboxed—one crash should never bring down the OS. • Virtualization-Based Security (VBS) enabled by default, but optimized to avoid performance loss. • Modular updates—fix or update parts of the OS without requiring a full reboot. Summary Project Diamond envisions Windows 12 as the system Windows 8 was meant to be: • Fast ⚡ • Clean 🧼 • Modern 🌐 • Stable 🛡️ A true rebirth of Windows speed and clarity—this time without the mistakes of the past.
