Microsoft is now testing a new update for Windows 10 21H1 in the Release Preview Channel of the Windows Insider Program. The update is described as KB5005611, and it includes a slew of non-security fixes expected to roll out with the next official cumulative update.
The update KB5005611 bumps the version number of Windows 10 to build 19043.1263, and it addresses language problems with the out-of-box experience (OOBE), system time showing incorrect information, and high processor usage with the DnsCache service.
In addition, this update fixes NumLock state after a Fast Startup restart, limitation of 25 maximum Traffic Selectors in the native Internet Key Exchange (IKE) client and server, PIN authentication over a virtual private network (VPN), a memory leak in the lsass.exe and explorer.exe services, and stop error after a restart.
It improved the performance of MsSense.exe in environments with User Datagram Protocol (UDP) applications that require high amounts of bandwidth. Also, build 19043.1263 removes a hyperlink that might cause the Input app to stop working when you first enter fuzzy pinyin content, and more.
