A default function of the Windows 11/10 operating system is Windows update that allows the constant optimization of the system configurations. However, during the download of each update, data and errors generated in the process are usually stored on the computer's local disk. This is why users should clear Windows update cache, which helps to fix errors that occur during an update and delete data to free up large root space. In this way, we explain step by step 4 simple and safe ways that allow you to clear Windows update cache.

Where Is the Windows Update Cache Folder?

Once the Windows operating system is automatically updated, a folder is created on the local disk of the computer that contains all the data and errors generated during the installation of Windows Update. To locate it you just have to go to the local disk (C:), access the Windows folder where you will see another folder called SoftwareDistribution and within it, you will find four files that contain the cache data of the last system update.

Why Should You Clear Windows Update Cache?

We give you four important reasons why we recommend you should delete Windows Update cache:

  • The first is that it optimizes system speed and frees up needed local disk space.

  • Windows update cache is nothing more than temporary data that the OS uses during the update, but later has no use for the user.

  • Keeping Windows update cache can slow down your computer.

  • If they are not deleted, failures may occur in the system operation.

Is It Safe to Clear Windows Update Cache?

The answer is yes. If you do not decide to use this option because you fear that by deleting the cache data, you may lose valuable or necessary information for the computer to work properly, we assure you that this will not happen. The files that are saved on your computer after Windows update have a temporary utility, and are created specifically for the update phase. After that, they have no value since they are obsolete.

Contrary to what you might think, if you do not delete these data, the speed of your PC can be affected, since the local disk is overloaded with unnecessary information. Also, if you don't clear Windows update cache, your computer is prone to crashes or errors, because you may be keeping corrupted files, or because the system has been slowed down.
