You’re going to want to update right away, especially on Windows 11
If you are a Windows 11 user and your processor is an AMD Ryzen, you may have experienced significant drops in performance on your computer. After an initial patch was released to fix the bug, Windows 11 ended up making the problem even worse.
This time the Windows 11 update KB5007215 is expected to solve not only this problem, but also various crashes with Windows Explorer and memory leaks, lags on some bluetooth devices, and even the problems that prevented the Start Menu from starting.
On the security side, the company has detected that two of the fixed vulnerabilities have been actively being exploited, so it is essential to update your system as soon as possible. The list of affected products includes everything from Azure to Microsoft Edge, through Office, Visual Studio, the Windows kernel, to Windows Defender.

Compared to the mid-year cumulative update that fixed up to 116 vulnerabilities, this Tuesday patch is relatively little, even lower than that of October, which reached 71 bugs.
