A workstation was updated last night as apart of a critical security patch conducted by the Enterprise IT Security Team in response to a new vulnerability. The workstation uses Windows 11 but you are not sure what the exact update was supposed to change or modify, other than it was security related. Today the user of the workstation is complaining it is not displaying anything and the screen is black. You have confirmed the PC is powered on. What should you do next?
Reboot into Safe Mode and disable all startup applications
Reboot into Safe Mode and run diagnostics.msc -RunDiagnostics
Reboot into Safe Mode and rollback the update to see if it fixes the issue
Contact the Enterprise IT Security team to see if it is safe to rollback the update or if this is a known issue
Because the update was a critical security patch you should not make any changes like rolling back the update. Disabling startup applications is unlikely to solve the issue, and diagnostics.msc -RunDiagnostics is not a real command.
The safest first step is to contact the team that conducted the update and get more context. Rolling back the update could cause a security issue, and other users may have reported this same issue and possible solutions. Best to play it safe and get more information first.
