Windows10: How do I uninstall OneDrive app via powershell?

This is a complete PS1 script to remove all traces of if:

Import-Module -DisableNameChecking $PSScriptRoot\..\lib\force-mkdir.psm1
Import-Module -DisableNameChecking $PSScriptRoot\..\lib\take-own.psm1

echo "73 OneDrive process and explorer"
taskkill.exe /F /IM "OneDrive.exe"
taskkill.exe /F /IM "explorer.exe"

echo "Remove OneDrive"

    & "$env:systemroot\System32\OneDriveSetup.exe" /uninstall
}
if (Test-Path "$env:systemroot\SysWOW64\OneDriveSetup.exe") {
    & "$env:systemroot\SysWOW64\OneDriveSetup.exe" /uninstall
}

echo "Disable OneDrive via Group Policies"
force-mkdir "HKLM:\SOFTWARE\Wow6432Node\Policies\Microsoft\Windows\OneDrive"
sp "HKLM:\SOFTWARE\Wow6432Node\Policies\Microsoft\Windows\OneDrive" "DisableFileSyncNGSC" 1

echo "Removing OneDrive leftovers trash"

rm -Recurse -Force -ErrorAction SilentlyContinue "$env:programdata\Microsoft OneDrive"
rm -Recurse -Force -ErrorAction SilentlyContinue "C:\OneDriveTemp"

echo "Remove Onedrive from explorer sidebar"
New-PSDrive -PSProvider "Registry" -Root "HKEY_CLASSES_ROOT" -Name "HKCR"

echo "Removing run option for new users"
reg load "hku\Default" "C:\Users\Default\NTUSER.DAT"
reg delete "HKEY_USERS\Default\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" /v "OneDriveSetup" /f

echo "Wait for EX reload.."
sleep 15

echo "Removing additional OneDrive leftovers"
foreach ($item in (ls "$env:WinDir\WinSxS\*onedrive*")) {
    Takeown-Folder $item.FullName
    rm -Recurse -Force $item.FullName
}

If you want the easy uninstall way, Open cmd in admin mode, type in taskkill /f /im OneDrive.exe to terminate OneDrive process.

Then type in either %SystemRoot%\System32\OneDriveSetup.exe /uninstall if you’re using 32-bit or %SystemRoot%\SysWOW64\OneDriveSetup.exe /uninstall if you’re using 64-bit Windows 10.

Update: Function for forced directory creation:

function force-mkdir($path) {
if (!(Test-Path $path)) {
    #Write-Host "-- Creating full path to: " $path -ForegroundColor White -BackgroundColor DarkGreen
    New-Item -ItemType Directory -Force -Path $path
}}

Registry ownership assimilation:

    function Takeown-Registry($key) {
    # TODO does not work for all root keys yet
    switch ($key.split('\')[0]) {
        "HKEY_CLASSES_ROOT" {
            $reg = [Microsoft.Win32.Registry]::ClassesRoot
            $key = $key.substring(18)
        }
        "HKEY_CURRENT_USER" {
            $reg = [Microsoft.Win32.Registry]::CurrentUser
            $key = $key.substring(18)
        }
        "HKEY_LOCAL_MACHINE" {
            $reg = [Microsoft.Win32.Registry]::LocalMachine
            $key = $key.substring(19)
        }
    }

    # get administraor group
    $admins = New-Object System.Security.Principal.SecurityIdentifier("S-1-5-32-544")
    $admins = $admins.Translate([System.Security.Principal.NTAccount])

    # set owner
    $key = $reg.OpenSubKey($key, "ReadWriteSubTree", "TakeOwnership")
    $acl = $key.GetAccessControl()
    $acl.SetOwner($admins)
    $key.SetAccessControl($acl)

    # set FullControl
    $acl = $key.GetAccessControl()
    $rule = New-Object System.Security.AccessControl.RegistryAccessRule($admins, "FullControl", "Allow")
    $acl.SetAccessRule($rule)
    $key.SetAccessControl($acl)
}

function Takeown-File($path) {
    takeown.exe /A /F $path
    $acl = Get-Acl $path

    # get administraor group
    $admins = New-Object System.Security.Principal.SecurityIdentifier("S-1-5-32-544")
    $admins = $admins.Translate([System.Security.Principal.NTAccount])

    # add NT Authority\SYSTEM
    $rule = New-Object System.Security.AccessControl.FileSystemAccessRule($admins, "FullControl", "None", "None", "Allow")
    $acl.AddAccessRule($rule)

    Set-Acl -Path $path -AclObject $acl
}

function Takeown-Folder($path) {
    Takeown-File $path
    foreach ($item in Get-ChildItem $path) {

        }

I just know a CMD method to uninstall OneDrive:

  1. Open Command Prompt as Administrator

  2. Type in taskkill /f /im OneDrive.exe to terminate any OneDrive processes and hit Enter.

  3. Type in %SystemRoot%\SysWOW64\OneDriveSetup.exe /uninstall if you’re using 64-bit Windows 10 and hit Enter.

You won’t see a confirmation dialog or progress bar when you do this, but if you try searching for OneDrive, the app will no longer be found. Of course, your OneDrive folder and files, however, will still be available.


Here's Origami's CMD method in PowerShell:

ps onedrive | Stop-Process -Force
start-process "$env:windir\SysWOW64\OneDriveSetup.exe" "/uninstall"
