Hi,
It is seems that File like below are occupied by some services at OS level. Please make sure that all the services regarding instance PRD in services.msc are stopped so kernel switch can take place properly.
Unable to delete file \\HOSTNAME\saploc\PRD\SYS\exe\uc\NTAMD64\slcryptokernel.dll: Deleting '\\HOSTNAME\saploc\PRD\SYS\exe\uc\NTAMD64\slcryptokernel.dll' failed: The process cannot access the file because it is being used by another process
Best Regards, Prem
