Patch KB5016700 for Windows 11 fixes a bug that causes exceptionally high CPU usage.
A bug makes PCs with Windows 11 slower. A new patch should fix this error.
For some users, the current version of Windows 11 causes their PC to be slowed down by an exceptionally high load. A process called “sihost.exe” is responsible for this. This is a core component of Windows that supports, among other things, the taskbar, the start menu and graphical elements of the operating system.
“sihost.exe” causes high CPU usage
There could be several reasons for the high CPU usage, which unnecessarily slows down the PC for some users. One of them could be a bug in Windows 11 which in turn causes CPU error. For some users, this effect occurs, for example, when their PC creates recordings and logs for feedback. This process freezes, causing performance issues.
Patch currently still in the test phase
With the new patch KB5016700, Microsoft is now fixing this bug as part of the Windows Insider program. The update is currently still in the testing phase and should be released together with Windows 11 22H2. The patch also brings support for the improved Windows Defender and fixes two bugs with the Task View preview and Windows Tablet Mode features.
