onedrive_remove_complete.ps1

Performs a complete, multi-path uninstallation of Microsoft OneDrive with permanent startup suppression.

Overview

This script stops running processes, executes the official Microsoft uninstall utility against all known install paths (system and Office), removes scheduled tasks, and applies registry policies to prevent reinstallation.

Purpose

Performs a complete, multi-path uninstallation of Microsoft OneDrive with permanent startup suppression. Stops running processes, executes the official Microsoft uninstall utility against all known install paths (system and Office), removes scheduled tasks, and applies registry policies to prevent reinstallation.

Prerequisites

• PowerShell 5.1 or later
• Administrator privileges required
• No network requirements (local operations only)

Configuration

Required Inputs

• No runtime parameters required
• All operations use hardcoded paths and registry locations

Settings

• OneDrive Setup Paths: System32, SysWOW64, Office x86, Office x64
• Registry GPO Path: HKLM:\Software\Policies\Microsoft\Windows\OneDrive
• Registry Explorer Path: HKLM:\SOFTWARE\Policies\Microsoft\Windows\Explorer
• Registry Run Key: HKCU:\Software\Microsoft\Windows\CurrentVersion\Run

Data Sources & Priority

1. Hardcoded OneDriveSetup.exe paths (system and Office locations)
2. Registry keys for GPO, Explorer, and Run persistence
3. Task Scheduler for OneDrive scheduled tasks
4. WMI/CIM for system diagnostics

Behavior

1. Validates administrative privileges
2. Stops all running OneDrive processes
3. Executes OneDriveSetup.exe /uninstall for each found path
4. Removes all OneDrive scheduled tasks
5. Sets HKLM GPO DisableFileSyncNGSC=1 to prevent startup for all users
6. Removes HKCU Run key OneDrive entry
7. Sets Explorer policy to hide OneDrive from navigation pane
8. Reports completion status with reboot recommendation

Security Notes

• No secrets (API keys, passwords) are used or logged
• All actions confined to local files, registry, and task scheduler
• Registry modifications use Group Policy paths for proper enforcement

Exit Codes

• 0 : Success - all cleanup steps completed
• 1 : Failure - critical error (likely permission-related)
