KB5000842 update is causing high-pitched sound problems for some Windows 10 users


It is a few weeks since Microsoft released the KB5000842 update for Windows 10, and it wasn't long before the optional patch was linked to problems with game performance. These particular issues have been -- mostly -- resolved, but KB5000842 remains problematic with users of some 5.1 audio setups complaining that it has results in their computers emitting high-pitched noises.
For now, there is no proper fix, but Microsoft is investigating the problem and say that an update will be provided in a future release. In the meantime, the company offers up a workaround.
Microsoft issues emergency update to fix game performance problems caused by KB5000842 and KB5001330


Microsoft has acknowledged that "a small subset of users have reported lower than expected performance in games" after installing one of two recent Windows 10 updates, and issued a rare type of fix.
Gamers complained about dropped framerates and poor performance after installing the KB5001330 update, and the same report came from those who installed the preview version of the same update, KB5000842. Now the company is using a fairly uncommon Known Issue Rollback (KIR) to resolve the problems, just after NVIDIA issued advice of its own to affected gamers.
[UPDATED] NVIDIA has a simple, possibly inadvisable, solution for poor game performance caused by problematic Windows 10 updates


The issues caused by updates for Windows 10 have been varied and plentiful. With each new batch of updates, anyone willing to install them finds they are playing an unwitting game of Russian roulette; the patch may fix some problems, but the chances are that they will introduce new ones as well.
This month's KB5001330 update -- just like the non-security preview version from the previous month, KB5000842 -- was just the latest in a long line of bug-riddled updates. This time the plethora of problems includes a performance hit for a number of games and to help with this, NVIDIA has a simple (if slightly controversial) solution.

This monthly "C" release preview update aims to address a number of issues with the operating systems including problems with dark screens and other monitor glitches, and as well as system crashes associated with OneDrive.

While Windows 10 version 21H1 -- which is due for release soon -- may not bring much to the table in terms of new features, it's still an important release because of the number of problems it addresses.
If you have been following the development of Windows 10 21H1 here on BetaNews, you'll know that it is currently undergoing beta testing. There are already a decent number of bug fixes in the new release, but Microsoft has just pushed out a new cumulative update to beta testers that patches even more problems.
