KB5022286 january 2023 update windows server 2019 hyper-v

server Dell Inc. PowerEdge R6415

AMD EPYC 7351P 16-Core Processor (32 virtual) (X64)


After this update, hyper-v server started to slow on all vms

No cpu was used, but everything was still slow or freezing

rebooting the host hyper-v or a vm did not resolve the problem (did not reboot all vms, as rebooting one took 40 minutes)


Had to remove the update with this:

DISM /online /get-packages



dism /Online /Remove-Package /PackageName:Package_for_RollupFix~31bf3856ad364e35~amd64~~17763.3887.1.7

reboot (20 minutes)
