Cleaning the Disk C

My computer has only 1.8 G today, I found that directory C:\Users\Baikal\Downloads\WinSxS too large, there are many old system files editions here, so I download a small software[1] to clean it. 

I didn't backup my data and files of it , bless for me it won't have some error.

It becomes bigger no longer red.

All right, there is nothing wrong!
