Tell you the real solution! The truth is that WINDOWS (a large game, such as Sword Spirit, takes up a lot of space) is helping you install many backup files. Please delete all the contents in this folder directly: C: \ Windows \ Software Distribution \ Download. Clean up every day, and you will find that you have to clean up a lot of G space at one time. There is one more thing c needs to be deleted: Windows.old

Windows.old.000

Windows.old.00 1 These can also be deleted. This thing is the original system backup file. If you don't need to restore to the original system, you can delete it ... and save a lot of space. Rest assured, there is absolutely no pollution!
