Remove-OneDrive

A PowerShell script to fully uninstall Microsoft OneDrive from Windows, including a scheduled post-reboot cleanup task to remove leftover folders and files.

Requirements

• Windows 10 or 11
• PowerShell 5.1+
• Must be run as Administrator

Usage

Save the script as Remove-OneDrive.ps1 and run it from an elevated PowerShell session.

Basic uninstall (with interactive reboot prompt)

.\Remove-OneDrive.ps1

Uninstall and reboot automatically

.\Remove-OneDrive.ps1 -Reboot

Uninstall and block OneDrive from being reinstalled via Group Policy

.\Remove-OneDrive.ps1 -BlockReinstall

Combine flags

.\Remove-OneDrive.ps1 -BlockReinstall -Reboot

Parameters

Parameter	Type	Description
-Reboot	Switch	Automatically reboots after scheduling the cleanup task
-BlockReinstall	Switch	Sets a Group Policy registry key (DisableFileSyncNGSC) to prevent OneDrive from being reinstalled
-PostReboot	Switch	Internal use. Run by the scheduled task after reboot to complete folder cleanup
-UserProfilePath	String	Override the user profile path used for cleanup (defaults to $env:USERPROFILE)

What it does

1. Stops the running OneDrive process
2. Runs OneDriveSetup.exe /uninstall from System32 and/or SysWOW64
3. (Optional) Blocks reinstall via a registry policy key
4. Schedules a post-reboot task (runs as SYSTEM at startup) to remove leftover folders:
   • %USERPROFILE%\OneDrive
   • %USERPROFILE%\AppData\Local\Microsoft\OneDrive
   • %ProgramData%\Microsoft OneDrive
5. After reboot, the scheduled task runs automatically and deletes itself when done

Notes

• The script must be saved and run from a .ps1 file — it will not work when pasted directly into a PowerShell session, because it schedules itself as a post-reboot task using $MyInvocation.MyCommand.Path.
• The -BlockReinstall flag writes to HKLM:\SOFTWARE\Policies\Microsoft\Windows\OneDrive. This can be reversed by deleting that registry key.
• If you prefer not to reboot immediately, the cleanup task will run automatically on the next system startup.
