How You Can Delete Windows Update Files Completely

As a Windows user, you know that Windows updates are important for keeping your operating system secure and running smoothly. However, over time these updates can accumulate and take up a significant amount of storage space on your hard drive.

In this comprehensive guide, you’ll learn several methods for deleting unnecessary Windows update files safely and freeing up disk space.

Why You Should Delete Old Windows Update Files

Here are some key reasons for removing outdated Windows updates from your computer:

  • Frees up storage space: Windows updates, especially cumulative ones, can easily occupy 5-10 GBs over time. Deleting the update files you no longer need can reclaim a lot of disk real estate.
  • Improves performance: Having less clutter on your hard drive enables Windows to access files and load programs faster. Deleting junk update files can give you a nice performance boost.
  • Increases stability: Hanging onto useless updates for too long can sometimes destabilize your Windows installation and lead to crashes or slowdowns. Regular cleanup keeps things running smoothly.
  • Enhances security: If you don’t delete old updates, it creates more avenues for potential exploits. By removing unneeded files promptly, you minimize your attack surface area.

As you can see, periodically cleaning out obsolete Windows updates is beneficial for freeing up space, ensuring stability, and improving speed.

How to Find Windows Update Files on Your Hard Drive

Before removing Windows update files, you first need to locate where they are stored on your system. Here are the main folders that contain Windows updates:

  • C:\Windows\SoftwareDistribution\Download – Contains downloaded installation files for updates.
  • C:\Windows\WinSxS – Stores Windows system files and components, including from updates.
  • C:\Windows\Temp – Can include temporary updater files.
  • C:\Windows\WindowsUpdate.log – Logs details of installed updates.

In addition, the Windows.old folder holds your previous Windows installation, including old updates.

You can browse to these locations in File Explorer to view update files or purge unnecessary ones. Certain tools like Disk Cleanup will automatically find and delete many update files from these folders.

Method #1: Use Disk Cleanup

The easiest way to delete Windows update files is by using the built-in Disk Cleanup utility. Here’s how:

windows update cleanup
  1. Open Disk Cleanup by searching for it or going to Start > Accessories > System Tools > Disk Cleanup.
  2. Select the drive you want to clean up (usually C:) and click OK.
  3. Disk Cleanup will scan the drive and show you files that can be deleted.
  4. Check the box next to “Windows update cleanup” and click OK.
  5. Allow Disk Cleanup to delete all the checked update files and temporary data.

This will clear out most of the outdated Windows updates taking up space on your system. It deletes the update installer files from C:\Windows\SoftwareDistribution\Download.

software distribution

Key benefits:

  • Quick and easy way to delete Windows updates.
  • Removes installer files no longer needed after updates are installed.

Method #2: Manually Delete the SoftwareDistribution Folder

For more control over deleting Windows updates, you can manually remove the SoftwareDistribution folder where updates are stored before installation. Here’s how it’s done:

services utility tool
  1. Type services.msc into the Start menu to open the Services utility.
  2. Find the Windows Update service, right-click it and select Stop to stop the service.
  3. Open File Explorer and go to C:\Windows\SoftwareDistribution.
  4. Rename this folder to something like OldSoftwareDistribution.
  5. Go back to Services and restart the Windows Update service.
  6. A new empty SoftwareDistribution folder will be created.
  7. You can now delete the old renamed folder to remove the update files.

This deletes the core Windows Update data folder so all new updates will install to a fresh empty folder. It clears up more space than using Disk Cleanup.

Key benefits:

  • Removes the main update installer folder completely.
  • Forces Windows Update to recreate the folder from scratch.
  • Allows more control over the process.

Method #3: Use the Windows Update Assistant

  3. On the screen that appears, click “Search for updates” and let it install any available updates.
  4. Once done, click “Check for updates” again even if none are found.
  5. Select “Review optional updates” and uncheck any you want to delete.
  6. Click Next to remove the unchecked optional updates.

This will uninstall optional Windows updates you no longer want, freeing up space taken up by their files.

Key benefits:

  • Easy interface for managing Windows updates.
