Microsoft recently recognized two bugs in Windows 11 that could crash applications or slow down your entire system. With the latest security update (KB5008215), Microsoft has fixed both known issues, underscoring the severity of this issue. In its changelog for the Patch Tuesday update, Microsoft confirmed that the fix now applies to all configurations.
A bug in Windows 11, which was detected in August 2021, could slow down the entire system by affecting the read or write speeds of the storage drives. This is particularly frustrating as almost all storage drives are affected and it also leads to performance issues with applications installed on the system drive.
If your device is affected, the storage drive could run 50% slower and write speeds would be the most affected. On November 22, Microsoft released an optional cumulative update and confirmed that the issue had been fixed with the fixes listed, explaining that this issue only affects the Windows drive.
“This problem occurs only when NTFS USN journal is enabled. Note that the USN journal is always enabled on disk C: ”Microsoft noted in the change log.
With the release of Patch Tuesday, Microsoft is finally rolling out the fix for everyone running Windows 11 version 21H2. As this is a security update, it will be downloaded and installed automatically based on your Windows Update settings.
Microsoft fixes apps that block Windows 11 errors
If you’ve upgraded to Windows 11 and are having trouble launching certain apps, you’re in luck, as Microsoft has finally fixed a strange bug that crashes apps in this update.
In the release notes, Microsoft explained that it has fixed an issue that could prevent applications, such as Kaspersky’s, from starting. This happens when you try to repair or update applications by using Microsoft Installer (MSI).
Kaspersky has also confirmed that a Windows 11 bug affected its antivirus in Windows 11 after an update was released in November. If you skip the update, Kaspersky Antivirus may no longer work, depending on the security company.
