 . Next, open an elevated command prompt window and //cd// to:
-    C:\Program Files\Microsoft\OnlineManagement\Common
+  C:\Program Files\Microsoft\OnlineManagement\Common

 . Run the following executable, along with its parameters, in the command prompt window:
-    ProvisioningUtil.exe /UninstallClient /ServiceId {GUID} /TaskName “tempTask” /SubEventId 16
+  ProvisioningUtil.exe /UninstallClient /ServiceId {GUID} /TaskName “tempTask” /SubEventId 16
 **Note**: Substitute {GUID} with the Intune service's GUID obtained in Step 2.\\

-The above steps have been compiled into a self-contained script package, which can be downloaded [[https://jsanders.me/wiki/lib/exe/fetch.php?media=files:uninstall-intune.zip|here]]. Extract all files from the zip file into a single location, then run the batch script as administrator.
+Paste the below script into an elevated PowerShell console to automatically retrieve the Intune service GUID and substitute it into the uninstall script. This will completely uninstall the management agent upon successful run.\\
