🔍 What is KB5062660?

• KB5062660 installs Windows 11 OS build 26100.4770, releasing new features and bug fixes, but no security updates, as it’s a preview update meant to preview what becomes the August Patch Tuesday release.

• Key highlights include:

  • Quick Machine Recovery: A self-healing feature that detects boot failures and applies fixes via WinRE and Windows Update, helping restore your PC automatically after critical errors.

  • New “Black Screen of Death” UI: Modernized crash screen design aligning with Windows 11 aesthetics (removing frowny face/QR codes) with quicker resolution times and context for stop codes.

  • Recall Export Functionality (available in the European Economic Area): Allows exporting snapshots via a unique export code, plus resetting Recall data and enhanced privacy control.

  • Improved Windows Search, updated Task Manager, File Explorer fixes, and performance improvements across zipped file extraction, menus, and storage icons.

  • Several bug fixes, including correcting false firewall Event 2042 logs, resolving Settings app hangs (e.g. when reopening a laptop lid), improving LSASS stability, ReFS backup memory exhaustion, and resolving Thunderbolt GPU detection issues.

⚠️ Known Issues and Cautions

• Many users have reported installation failures, including errors like 0x80073712 or 0x80070306, especially on Insider Release Preview channel builds (e.g. transitioning from 26100.4767 to 26100.4770).

• Reports of system instability, including BSODs, printer removal, taskbar/start menu crashes, or other freeze issues—particularly on machines upgraded to Windows 11 24H2 and after installing preview builds.

• Example Reddit feedback:

  “This update broke my whole install… reinstalling Windows 11 now because of this … intermittent chrome freezing…”

  And others experienced blank icons, missing applications, USB power issues or severe instabilities

✅ Should You Install It?

This is an optional preview update, which means:

• It contains no security fixes; those will arrive in the official August Patch Tuesday update.

• You’re not required to install it—and skipping it does not expose you to security vulnerabilities.

Recommended:

• If you’re not comfortable experimenting with preview features, or if you rely on your PC for critical tasks: Don’t install yet.

• Wait for the official release (expected second Tuesday of August 2025), which will contain these updates in final, stable form.

🚫 If You Faced Issues or Want to Avoid It

How to hide or block this optional update:

• Turn off the setting “Get the latest updates as soon as they’re available” in Settings → Windows Update.

• Use the Microsoft “Show or Hide Updates” troubleshooter tool to hide KB5062660 so it doesn’t get re-offered.

If installation fails or causes issues:

• Try Windows Update troubleshooter, clear SoftwareDistribution cache, perform SFC/DISM checks, boot in Clean Boot mode, and install manually via Microsoft Update Catalog—but many users still report failures.

• If issues persist, consider uninstalling KB5062660: go to Settings → Windows Update → Update history → Uninstall Updates, find and remove KB5062660, then restart. Possibly pause updates temporarily.

• Some users resolved recurring failure by performing a Windows 11 repair/reinstall using the latest ISO while preserving files and apps.
