svchost.exe high CPU usage - solved
I dont know when it started happening, but I was getting a CPU spike from svchost.exe on startup
This lasted about 30 seconds then the CPU cooled off.
I found that Superfetch was causing it.
By disabling Sysmain service the CPU spike seems to have been resolved
The specific service under svchost.exe was UdkUserSvc causing the high CPU usage; spike.

A temporary CPU spike caused by svchost.exe during startup is quite common and usually normal. svchost.exe is a generic host process for Windows services, and many system functions run under it. However, if the spike lasts longer than a few seconds or happens frequently, it may indicate underlying issues.
Certain services, like Windows Update, Defender, or indexing, can temporarily cause svchost.exe to spike.
Just to clarify:
