How to uninstall a Windows update

If a problem started right after an update, removing that update can fix it. Your files and apps are not affected, but you lose the security fixes the update brought until you install it again.

Time
5 to 15 minutes plus a restart
Level
Easy
You need
An administrator account. For the recovery method on an encrypted device, the BitLocker recovery key.

Before you start

  • Check when the problem started: in Update history every update has its install date.
  • Removing a security update leaves the PC open to the flaws it fixed. Plan to install the update again once the problem is solved.
  • If the problem started after an upgrade to a new version of Windows, you can go back to the previous version instead. That option is available for 10 days after the upgrade.

Windows 11

Steps written for Windows 11 25H2 and 26H2.

  1. Open Windows Update

    Select Start > Settings > Windows Update.

  2. Open the update history

    Under More options, select Update history. Note the KB number and the date of the update you suspect.

  3. Open the list of removable updates

    Scroll down to Related settings and select Uninstall updates.

  4. Uninstall the update

    Find the update in the list and select Uninstall next to it. If the update is not in the list, Windows does not allow it to be removed this way.

  5. Pause updates

    Go back to Settings > Windows Update and select Pick a date on the Pause updates control. If your PC shows a list there instead, select the pause length you prefer. Without a pause Windows downloads the same update again.

Steps checked against Microsoft's documentation on Oct 11, 2026.

Uninstall an update with a command

Open Command Prompt as administrator and run the command below with the number of the update in place of NUMBER (for KB5001234, type 5001234):

wusa /uninstall /kb:NUMBER

On current versions of Windows 11 this often does not work for the monthly cumulative update. Microsoft ships it in one package with the servicing stack update, and wusa cannot remove that package. Microsoft's own instructions for that case use DISM. List the installed packages, find the name of the update's package, then remove it by that name:

DISM /online /get-packages
DISM /Online /Remove-Package /PackageName:NAME

Updates that cannot be removed

  • Servicing stack updates. Microsoft states that the servicing stack update cannot be removed from the system after it is installed.
  • Updates without an Uninstall option. Microsoft notes that some updates cannot be uninstalled. They do not appear in Uninstall updates.
  • A new version of Windows. A version upgrade is undone with the go back option, not from the update list, and only for 10 days.

If the update you suspect cannot be removed, Undo recent changes with System Restore can take Windows back to a restore point made before it was installed.

Why the update comes back and how long you can pause

Windows Update installs missing updates on its own, so a removed update returns with the next check. A pause stops that for a while. On Windows 11 you can pause for up to 35 days from today and extend the pause later. When the pause ends, Windows checks for updates and installs the latest ones. You cannot turn updates off for good, and you should not try: Microsoft warns that a PC without security updates is open to known attacks.

Use the pause to wait for a corrected update, then install it. If the update fails to install, see Run the Windows Update troubleshooter.

How to put the update back

Open Settings > Windows Update (on Windows 10: Settings > Update & Security > Windows Update), resume updates if they are paused and select Check for updates. Windows downloads and installs the update again. To install one specific update by its KB number, see Install an update from the Microsoft Update Catalog.
