Windows updates are actually meant to seal security holes and remove bugs, but sometimes they also create new ones when they try to do so. Microsoft’s August updates cause some Windows 11-based machines to only boot to BitLocker recovery. Windows 10 users, on the other hand, might be affected by sound issues.
In the Windows Release Health Notes for Windows 11, Microsoft writes that the August 9 update to the Secure Boot Database (Secure Boot DBX, KB5012170), which should actually block insecure boot loaders , it is used to start the computer in BitLocker. result. This can happen after the first or second reboot after installing the update. It’s important for Microsoft to point out that this happens separately from Windows Cumulative Update, roll-ups, or similar updates.
If this happens, those affected can enter their BitLocker key by the usual methods and thus free the hard drive again. If the key is not backed up, access is blocked and the data or operating system is gone.
In Microsoft explains the version status entryhow users can temporarily disable BitLocker before installing the potentially dangerous patch. After installation, drive encryption can be turned back on without the dreaded side effects. If users have already rebooted twice or more, they are not affected by the issue. Microsoft vaguely promises a remedy in one of the next releases.
Some users with Windows 10 21H2, 21H1, and 20H2 updates may experience slightly less severe sound issues after applying the August patches to their Windows. Some of the affected devices no longer make any sound, on other machines only certain ports, audio devices or even apps or games are affected.
In most of the affected device drivers, the “Audio Enhancements” option was disabled before the Windows Update was installed, or the driver had issues with the feature. Microsoft is discussing various ways to fix the problem. If the update is not yet installed, users should check for updated sound drivers, either through Windows Update or from the hardware manufacturer. Users of advanced audio applications such as Open Broadcaster Software (OBS) should back up all their settings before upgrading.
If only some apps are affected, users should check if the correct audio devices have been selected for output on them. If necessary, a complete software reinstall now with no sound would help, or manufacturer support, which would have to explain how to set the correct audio output devices (Media Device ID, MMDevice ID).
If the whole system remains without sound output, users can use the Wizard to fix sound or audio problems in Windows start from the website; This should solve the problem. As a last help, the manufacturer refers to one Help article on how to disable audio enhancements explained.
Microsoft has also marked the issue as resolved. The company simply removed the update via a known problem rollback (KIR). However, this does not help if the error has already occurred. This still remains and requires one of the above solutions. Like the same speed up KIR or configure it on managed networks leaves, explains the message from Microsoft as well.
OS updates causing issues on some devices is now almost a normal scenario. More recently, Microsoft’s May update previews had to deal with major issues.
