NightCrawler released another window's vuln.

From what I can understand of it:

* Read the target user's NTUSER.DAT hive into memory as a backup.

* Open the hive offline using the Offline Registry (offreg) API.

* Modify HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Local AppData to point at \\.\GlobalRoot\BaseNamedObjects\Restricted.

* Save the modified hive and replace the original NTUSER.DAT.

* Copy the user's UsrClass.dat into the temporary working directory.

* Acquire a batch oplock on the copied UsrClass.dat to synchronize execution with profile loading.

* Start a suspended process using CreateProcessWithLogonW(..., LOGON_WITH_PROFILE, ...), triggering the User Profile Service to load the profile.

* Wait for the oplock to break when Windows attempts to access UsrClass.dat
