How to use the Windows 10 clean up tool

Last updated: November 12, 2026 8:00:00 AM

Free up space on your device by removing unneeded system files. Follow these simple steps to run the built-in storage utility.

To use the built-in Windows disk cleaning utility, open the Start menu, type the name of the tool, and select it from the search results to scan your system drive. Over time, computers running Microsoft operating systems accumulate a massive collection of unnecessary files. These digital leftovers come from web browsing, software updates, temporary installations, and system error logs. Left unchecked, this clutter takes up valuable storage space and can eventually slow down day-to-day operations. Fortunately, every modern version of the operating system includes a dedicated utility designed specifically to locate and remove these redundant items safely.

Understanding how to navigate and operate this maintenance feature allows anyone to reclaim gigabytes of storage without installing third-party software or risking the deletion of important personal files. Here is how to complete the process safely and effectively.

Prepare the System Before Scanning

Before launching any utility that deletes data, it is wise to perform a few basic housekeeping steps to ensure the application can work as efficiently as possible. Close out of all active web browsers, word processors, and background applications. Browsers, in particular, hold onto cache files while running, which prevents the cleanup utility from clearing those specific temporary directories.

Next, empty the Recycle Bin manually if you have not done so recently. While the system maintenance utility can handle this task, doing it beforehand gives you a clear baseline of how much loose clutter is actually sitting on the hard drive. Take a moment to save any open work and close active windows. Ensuring a stable, quiet system state allows the upcoming disk scan to run smoothly from start to finish without interruption.

Open the primary search bar located on the taskbar and type the exact name of the utility, which is Disk Cleanup. As you type, the desktop application will appear at the top of the search results list. Click on the application icon to open it.

Upon launching, a small dialogue box will appear prompting you to choose which drive you want to examine. By default, the operating system drive—usually labeled as the C drive—is selected. Leave this default selection in place, as this is where the vast majority of temporary operating system files, update caches, and residual installation packages accumulate. Click the okay button to proceed. The application will then take a brief moment to calculate how much space can be freed up on that specific drive. The time this takes depends on how long it has been since the drive was last cleared and the overall speed of the computer's storage hardware.

If you are unsure what a specific category contains, click on its name to read the brief explanatory text provided in the description box below the list.
