Disk Cleanup is a free computer maintenance utility designed to free up disk space on a Windows computer’s hard drive. The tool searches and analyzes the files and folders stored on your hard drive and then removes the unnecessary ones. Having empty space on your hard drive is important if you want to keep your PC running smoothly.

If you’ve used Disk Cleanup, you may have noticed that sometimes the tool displays 20x more hard drive space than the manufacturer’s capacity. Actually, this is an old bug affecting many Windows OS versions.

Microsoft has already acknowledged that Windows 10 version 1607 is affected by this issue, as well, and says that the bug was fixed with Windows 10 build 15002. In other words, for the time being, Disk Cleanup displays the correct HD free space only on Insiders’ computers.

The good news is that this bug is going to be fixed with the Windows 10 Creators Update. This was recently confirmed by one of Microsoft’s engineers on Reddit. Some users joked when they heard the news, asking what took Microsoft so long to fix this old bug:

wooo. I’m curious how a 20 year old bug that seemed like it was never going to get fixed, suddenly became fixable, or if it was just worked around for Disk Cleanup‘s specific common case?
