delete-gcpw-users.ps1

#### This script will delete all local users except for the admin account, the default Windows accounts,
#### and the account used for GCPW to function (gaia).

## If MDM is configured through GCPW, make sure you add an exception for the user that enrolled the device.
## Otherwise their account will be deleted, and MDM will be unenrolled.

####### Hastily written and barely tested, but tested in production! Use at your own risk. #######
