The Disk Cleanup utility is one of the utility tools built into the Windows platform. The Disk Cleanup utility helps remove files (i.e. junk files) that are no longer in use. It helps to free up disk space and speed up the computer. You should do this from time to time to delete unnecessary files that are not in use.

Some of the types of files that are deleted during Disk Cleanup are:

  • Downloaded program files, temporary Internet files, error report files, temporary files and thumbnails, etc.

You need to follow the below steps to run the Disk Cleanup utility in Windows 10:

Step 1:

In the Windows search bar, located in the lower left corner of the screen, type "disk cleanup". Click "Free up disk space by deleting unnecessary files" as shown in the following screenshot:

Note: For a more relevant search experience, the second option in the search is preferred over the first option.

Step 2:

Click the drop-down list to choose the hard drive on which to run “Disk Cleanup” and click “OK”. For example, say (C 🙂

Disk Cleanup will start scanning the selected hard drive and calculate how much space it can free from it. You can click "Cancel" to cancel the instruction (not recommended).

Note: It may take a few minutes depending on the number of unnecessary files on your computer.

Step 3:

Now you can choose the file categories you want to delete. You can check the boxes provided to delete a certain set of files. After selecting the type of file to delete, click "OK".

Step 4:

A confirmation window will appear on your screen. Click "Delete File" to continue.

The Disk Cleanup utility will delete the files and the window will close automatically.

Note: Clicking "Cancel" will cancel this task, so it is not recommended.
