Disable BitLocker

Based on all the ruckus caused by KB5012170, if you are able, determine if BitLocker is active, and if so and if undesired, disable it on all drives before rebooting your computer running Microsoft Windows 10/11.

PS C:\WINDOWS\system32> Get-BitLockerVolume

It looks like my computer is in the clear. If it hadn’t been, then I would run these two commands.

PS C:\WINDOWS\system32> $BLV = Get-BitLockerVolume
PS C:\WINDOWS\system32> Disable-BitLocker -MountPoint $BLV
