For example, an application would look for a specific version of a DLL file, but find a newer version that was recently updated by another program.

If you used the Windows operating system back in the Windows 9.x days, you’re familiar with the term DLL Hell. Note: Before you attempt any of the steps shown in this article, I recommend that you restart your system to ensure that any pending Windows Update operations are complete and to ensure you are beginning with a clean slate.

This feature is designed to help you regain valuable hard disk space by removing system files that are no longer necessary to the functioning of the operating system–old installation files, Windows Update leftovers, and outdated device drivers, just to name a few. Windows 10 has a feature built into the Disk Cleanup tool called Clean Up System Files that not many people take full advantage of. For more info, visit our Terms of Use page.
