Taming the Restless Machine: Fixing Windows 11's Shutdown Loop (KB5073455)
If your Windows 11 PC has started a frustrating ritual of restarting instead of shutting down after a recent update, you are not alone. This is a known conflict between a security guard and a new instruction.
The Problem: KB5073455 Shutdown Loop
The culprit is the January 2026 update KB5073455, which clashes with System Guard Secure Launch on Enterprise and IoT editions.
The Permanent Fix: KB5077797
Microsoft released an emergency out-of-band update, KB5077797, on January 17, 2026.
- Download: Visit the Microsoft Update Catalog.
- Search: Look for "KB5077797".
- Install: Download the correct version for your architecture (usually 64-bit) and restart.
Interim Workaround: Command Line
If you cannot install the fix immediately, use the Command Prompt to shut down cleanly:
shutdown /s /t 0
Note: This bypasses the graphical menu and is far safer than holding the physical power button.
Proactive Steps for Stability
- Check Release Health: Microsoft's official documentation notes known issues for each update.
- Recovery Tools: Settings > System > Recovery > "Fix problems using Windows Update".
O Allah, never let the world forget the suffering of our brothers and sisters in Palestine. Shower them with Your mercy, steady their hearts with patience, and replace their every tear with the light of peace. O Most Merciful, be their protector, their healer, their unbreakable hope. Ameen, ya Rabb al-ʿālamīn.
