Microsoft has officially posted an online bulletin confirming that they are actively investigating the reports.

However, the sheer size and complexity of this update led to a severe conflict in the Windows boot sequence. When affected users attempt to turn on their computers, the system attempts to initialize the new security protocols but ultimately fails. Instead of loading the desktop, the PC gets stuck in a boot loop or displays a critical failure screen, effectively locking users out of their data.How to Rescue Your Unbootable PCIf your Windows 11 machine is refusing to boot, you cannot simply uninstall the update from the standard settings menu. You need to force the computer into the Windows Recovery Environment (WinRE) to manually roll back the patch.Step 1: Force the Recovery MenuTurn on your PC. As soon as you see the Windows or manufacturer logo, press and hold the physical power button for about 10 seconds to force it to shut down.Turn on the PC again, and repeat the hard shutdown when the logo appears.Turn on the PC a third time. This time, let it run. Windows will detect the repeated boot failures and automatically launch the Automatic Repair screen.Click Advanced Options to enter the Windows Recovery Environment.Step 2: Uninstall the July UpdateFrom the "Choose an option" screen, click Troubleshoot.Select Advanced options.Click on Uninstall Updates.Choose Uninstall latest quality update. (Security patches like the July Patch Tuesday update are categorized as quality updates).Follow the on-screen prompts to confirm the removal, and then restart your computer.Once the broken update is rolled back, your system should boot up normally.Pause Your Updates!Because Microsoft is still actively investigating this issue, you need to prevent your PC from immediately re-downloading the broken patch the second you connect to Wi-Fi.Once you are back on your desktop, go to Settings > Windows Update and click Pause updates for 1 week.
