If you run out of free space on your PC, it can affect your PC's performance: resulting in failure to complete important Windows system updates, inability to install new programs, slow PC performance, stuttering, and many other issues. Here's how to free up disk space so you can keep your PC up to date and running smoothly. For PC non-professionals, it can also be easily performed.

Free up disk space with Disk Cleanup

Usually computer disks are divided into C drive, D drive, and E drive. C drive is used to store installed programs and user information. D drive and E drive are used to store data such as photos or videos. Clean up the D drive and E drive, just delete the unnecessary data. So how to clean up the C drive used to store the Windows system? As we all know, the files in the C drive cannot be deleted at will to avoid system crash. Here you can use Disk Cleanup to clean up the disk, which is an officially recommended program without any side effects.

Step 1. Run the Disk Cleanup utility

Press Win+S to open the search window, then type Disk Cleanup, and then select it from the results.

Step 2. Choose the target drive

Please click the drop-down arrow and select the drive you want to clean up. Then click the OK button to scan the drive.

Step 3. Select items

After the scan is completed, please select the check boxes next to the file types you want to delete.

By default, Downloaded Program Files, Temporary Internet Files, and Thumbnails are selected. If you do not want to delete these files, clear the corresponding checkboxes.

If you want to further free up more space, select Clean up system files. Then select the type of system file you want to delete. Since system files can be large, Disk Cleanup will take some time to calculate the amount of space that can be freed.

After selecting the file types to delete, select OK, and then select Delete files in the confirmation window to start the cleanup.

Microsoft has also issued a note: If you upgrade to Windows 11 less than 11 days ago, your previous version of Windows will be listed as a system file that you can delete. If you need to free up drive space, you can delete it, but keep in mind that you'll delete the Windows.old folder, which contains files that give you the option to go back to a previous version of Windows. If you remove a previous version of Windows, you cannot undo it. (You will not be able to go back to the previous version of Windows.)
