Windows updates have always been hit and miss for quality and system improvements, a lot of the time Microsoft releases an update that aims to improve overall system functionality, they also seem to introduce other major issues. Over the years we’ve seen updates lose user files, cause high CPU usage, prevent files from being located or moved, and a ton of others.

The latest Windows 11 update KB5007297 has continued this tradition wholeheartedly with major performance losses across the entire operating system. How? Well after installing Windows 11 update KB5007297 some users have reported major CPU and RAM usage increases. For example, on my AMD machine, idle CPU usage has risen from 1-2% to 12-19% constantly while RAM at idle has risen from 38% to 50%. The same issues have been reported on Intel systems. If you have quite a powerful PC you probably won’t notice the major drop unless you are familiar with the benchmarks your system had before the update.

So is there anything you can do about the performance issues of KB5007297? Nope! The only thing you can do to solve this problem is to uninstall the update and revert back to an older version of Windows 11. At least until they solve the problem in a newer version.
