Quick Way to Schedule Reboot in Windows
article #467, updated 62 days ago

Run these in an administrative or SYSTEM-level command prompt.

Under 7/2008R2 and before, we can schedule for 4:00 AM tomorrow:

AT 4:00 c:\windows\system32\shutdown.exe -f -r -t 0

and we can schedule for 4:00 AM next Monday:

AT 4:00 /next:Monday c:\windows\system32\shutdown.exe -f -r -t 0

In Windows 8.1/2012R2 and later it’s a bit harder, we have to specify the actual full date in the format below:

schtasks /create /tn "schtasks_REBOOT" /tr "C:\Windows\System32\shutdown.exe -f -r -t 0" /sc once /st 04:00 /sd 01/01/2016 /ru System

8.0 and 2012R1 appear to require a “/Y” on the very end.

Bluescreen at boot with win32k.sys error
article #1022, updated 68 days ago

If Windows 7 won’t boot all the way, if it gives a bluescreen involving win32k.sys, it may be a bad update. Boot into startup repair and rename FNTCACHE.DAT in system32 to .OLD. That forces Windows to make a new one and boot will occur next time.

Remote Procedure Call Locator (RPC Locator) Service
article #1020, updated 73 days ago

This is a service to be found in many versions of Windows, but its in-OS documentation states that it is present for application compatibility only. And yet on at least one LAN it has been seen to be essential for printing. Research has provided no results. Anyone with input, please contact me by email!
