The 'WmiPrvSE.exe' process is not controlled by the update wizard. You have to…

When upgrading a SQL Server 2008 R2 cluster to service pack 1 (SP1), you might get the following message as you’re plowing through the wizard screens:

The 'WmiPrvSE.exe' process is not controlled by the update wizard. You have to manually stop this process to avoid a computer restart.

You might find several threads in task manager for WmiPrvSE.exe, and trying to kill them will only find them restarting/returning back. Instead, do Start>>Run>>Services.msc, locate the Windows Management Instrumentation service, and stop the service. Then you can continue the install on n node without having to reboot that node. Restart the service and you’re good.

Thanks,
