Version history:
1.0 - Script created
1.2 - Added test for pending reboots. If reboot is pending, RSAT features might not install successfully
Added test for configuration of local WSUS by Group Policy.
- If local WSUS is configured by Group Policy, history shows that additional settings might be needed for some environments
1.3 - Now using Get-CmiInstance instead of Get-WmiObject for determining OS buildnumber
