You can stop a Windows update in progress, but the method depends on which stage it's in
If Windows is downloading or installing an update right now, you have a few options to pause or cancel it — though some work better than others depending on how far along the process is. The easiest route is to pause the update before it installs, which you can do from your Settings menu. If the update is already installing, you may need to restart your computer or use the command line. Once an update has finished installing and restarted your computer, you cannot undo it through cancellation — you would need to uninstall it afterward, which is a different process.
The stage your update is in determines what you can actually do right now. A read in progress can be paused for weeks. An installation already underway can be interrupted by restart, but may resume later. A finished update cannot be cancelled, only removed. Understanding where your update sits in this timeline helps you choose the right action without accidentally damaging your system.
Key Takeaways
- You can pause a Windows update that is downloading by opening Settings, going to Update & Security, and selecting Pause Updates for up to 35 days.
- If the update is already installing, restarting your computer will usually stop the installation process, though Windows may resume it later.
- Once an update has completed and your computer has restarted, you cannot cancel it — you can only uninstall it if problems occur.
- Stopping updates temporarily is different from disabling Windows Update entirely, which requires changes to your system services.
How to pause an update that is downloading
Open the Settings app by pressing the Windows key and typing "Settings," then pressing Enter. Click on "Update & Security" in the left sidebar. You should see a section labeled "Windows Update" with information about your current update status.
If an update is downloading, you will see a button that says "Pause for 7 days" or similar. Click it. Windows will stop downloading the update and will not resume for the number of days shown — usually up to 35 days depending on your Windows version. During this pause period, you can use your computer normally without the update running in the background.
When the pause period ends, Windows will resume downloading the update automatically. If you want to extend the pause, you can return to the same Settings screen and pause again before the timer runs out.
How to stop an update that is already installing
If the update has moved past downloading and is now installing, pausing from Settings may not work. The fastest way to interrupt the installation is to restart your computer. Press Ctrl + Alt + Delete, select "Restart," and click "Restart anyway" if prompted.
When your computer restarts, Windows will usually stop the installation process. However, Windows Update may resume the installation the next time you shut down or restart, so this is a temporary stop rather than a permanent cancellation. If you want to prevent it from resuming, return to Settings > Update & Security and pause the update as described above.
Do not force shut down your computer by holding the power button, as this can corrupt files or damage your system. Use the restart option through the operating system instead.
What happens after an update has finished installing
Once Windows has completed the installation and your computer has restarted, the update is now part of your system and cannot be cancelled. At this point, your only option is to uninstall the update if it causes problems — for example, if it breaks a program you use or causes your computer to run slowly.
To uninstall a recent update, open Settings, go to Update & Security, and look for "View update history" or "Uninstall updates." Windows will show you a list of recent updates with dates. Find the update you want to remove, click it, and select "Uninstall." Your computer will restart, and the update will be removed. This process can take 10 to 30 minutes depending on the size of the update.
The difference between pausing and disabling Windows Update
Pausing an update is temporary and affects only the current update — Windows Update itself remains active and will resume after the pause ends. Disabling Windows Update entirely is a different action that stops all updates from downloading or installing until you turn the service back on.
Most people should not disable Windows Update, because updates include security fixes that protect your computer from viruses and hackers. Pausing for a few weeks while you finish a project is usually safe, but leaving updates disabled for months creates a real security risk. If you need to disable updates temporarily, you can do so through Services (press Windows key + R, type "services.msc," and find "Windows Update" in the list), but you should turn it back on as soon as your when ready need is finished.
Why Windows restarts during updates
Windows restarts during an update because the operating system itself is being changed, and those changes cannot take effect while Windows is running. Think of it like replacing the engine of a car — you have to turn the engine off first. The restart is not a sign that something went wrong; it is a normal part of the installation process.
If you see a notification that says "Your computer will restart in 15 minutes," you can click "Restart now" to begin the restart when ready, or you can wait for the automatic restart. Either way, the update will complete during the restart. If you have unsaved work, save it before the restart begins.
What to do if an update keeps trying to install
Sometimes Windows will repeatedly try to install an update even after you have paused it or restarted your computer. This usually happens with large updates or security patches that Windows considers important. If this is interrupting your work, you have a few options.
First, check whether the update is actually paused by returning to Settings > Update & Security and confirming the pause is active. If the pause has expired, pause it again. Second, you can schedule the restart for a time when you are not using your computer — Windows will ask you to choose a time, and it will restart then instead of interrupting you randomly. Third, if the update is causing real problems, you can uninstall it after it installs, though you may need to pause it multiple times before you get the chance.
Frequently Asked Questions
Can I cancel an update that has already restarted my computer?
No. Once Windows has restarted and the update is installed, cancellation is not possible. Your only option is to uninstall the update afterward through Settings > Update & Security > View update history if the update causes problems.
Will pausing an update delay important security fixes?
Yes, pausing delays security updates for the duration of the pause — usually up to 35 days. Security updates are important for protecting your computer, so you should resume them as soon as your when ready need is finished. Pausing for a few weeks is generally safe, but leaving updates paused for months increases your security risk.
What if my computer restarts in the middle of my work?
Save your work frequently, and pause updates before you start a long project. If a restart happens unexpectedly, Windows will usually reopen your programs after the restart, though unsaved changes will be lost. To prevent surprise restarts, pause updates or schedule the restart for a specific time through the notification that appears.
Does restarting my computer stop the update permanently?
Restarting stops the current installation, but Windows Update will usually resume the installation the next time you shut down or restart. To prevent it from resuming, pause the update in Settings after you restart.
Can I delete the Windows Update files to stop an update?
You should not manually delete Windows Update files, as this can damage your system or leave it in an unstable state. Use the pause and restart methods described above instead, or uninstall the update after it completes if it causes problems.
