The Windows 10 operating system, like any other similar platform, receives regular updates. These updates are meant to resolve reported bugs and software related issues in order to improve the overall user experience. Of course, depending on each update and its importance, among different bug-fixes, these patches are including new features, system apps, and even new capabilities or security enhancements.
The update process is simple. You can get a notification based on which you can choose to apply a certain patch or not, or the new files are installed automatically in the background while you are still doing your work. Usually, this process is completed only after a reboot is performed.
But, as a general rule, after a Windows patch is installed on your computer, the patch file and other related packages will be cached inside a dedicated folder. These files that are stored by default are used when you decide to uninstall a certain patch or when you choose to restore system file that was previously removed from your Windows 10 computer.
While it’s not really recommended to delete essential installer directories, the cache folder that stores the installer patch files can be safely removed from your Windows 10 system. In this way, you can free up some space from your hard drive (especially if the space is already limited). Over time these patches might become quite numerous.
The installer patch files on Windows 10 are located under:
This is a system folder so it is hidden by default – you cannot access it unless you first enable this feature from Control Panel.
Before deleting these files, I recommend you back up the installer patch folder in order to avoid further unpleasant situations – you can just place a copy of this folder on a USB stick or on an external hard drive.
Moreover, keep in mind that it’s safe to delete only the baseline cache
Don’t remove anything that’s located under
If you make changes within that directory you might experience problems if you need to reinstall/repair the Windows 10 system.
How can I delete installer patch files on Windows 10?
1. Manually delete Windows Installer Patch files
- First, power on your Windows 10 computer.
- Log in using an administrator account – otherwise, you won’t be able to delete the installer patch files.
- From the main Windows, screen click on the Search field, located near the Windows Start icon (the same place from where you access Cortana).
- In the search field type cmd and press Enter.
- Now a command prompt window should be displayed on your computer.

So, those were the steps that must be followed if you want to delete installer patch files on Windows 10.
