Optional updates for Windows 10 and Windows 11 released in January have fixed performance problems when playing games, using the operating system, or even opening folders in File Explorer.
Microsoft later released out-of-band updates to fix these issues, whose fixes were also rolled into the optional preview updates.
These optional updates seem to have fixed more than the reported bugs, as they are also resolving significant performance issues caused by the January updates.
After installing the January 2022 KB5009543 update, Windows 10 users began to notice that Windows suffered from severe performance issues.
The good news is that BleepingComputer found that installing the optional KB5009596 preview update released late last month fixed these newly introduced performance issues.
Windows users can install the optional updates by going into Settings, clicking on Windows Update, and manually performing a 'Check for Updates.
