Problems with Windows 11 update KB5043145: What you need to know

The recent Windows 11 update KB5043145 released by Microsoft as an optional update has thrown up a number of critical issues for users.

This situation reminds us of similar difficulties encountered following security updates that happened just a few months ago.

Update KB5043145 was originally released as an optional update for users who have enabled the option to receive the latest available updates.

While this update brought bug fixes and some useful changes, like the return of the logout option to the profile menu in Start, it also came with a number of stability issues.

Main problems reported

Blue (BSOD) and Green (GSOD) error screens

Microsoft has confirmed the occurrence of these critical system errors.

In many cases, devices automatically enter “Automatic Repair” mode after repeated restart attempts.

System lock on startup

Many users reported that their devices stopped booting after installing the update.

The issue seems to be affecting some ASUS laptops (ROG Strix G17 and TUF A15 models) and Intel NUC systems in particular.

WSL2 no longer works

Users of AMD systems have reported that Windows Subsystem for Linux 2 (WSL2) stops starting, generating timeout errors.

Problems with USB ports

Some users have reported that USB ports and connected peripherals (such as mouse or keyboard) stop working after installing the update.

Other problems

In other cases, owners of computers with Windows 11 have noticed failures to install the update, with specific error codes, but also the disappearance of the Wi-Fi option from the system settings. The devices also reverted to Windows 10-style context menus.

Specialists’ recommendations

First, don’t install the KB5043145 update if you haven’t already, then turn off the “Get the latest updates as soon as they’re available” option in Settings > Windows Update.

If you have already installed the update and are having problems, follow the steps below to uninstall it manually:

1. Reboot your device and repeatedly press F11 key during boot to enter recovery mode.
2. Select “Troubleshoot” > “Advanced options” > “Uninstall updates”.
3. Choose “Uninstall last quality update” (should be KB5043145).
4. Reboot the system.

Alternatively, you can use the command line:
1. In the recovery menu, select “Command Prompt”.
2. Enter the command: `wusa /uninstall /kb:5043145`
3. Restart your device.

Microsoft is actively investigating these issues and expects to release an update to resolve them.

Until then, users are advised to take regular system backups and report any issues they encounter through the Feedback Hub app.
