How To Cleanup Winsxs

What is eating up my hard disk space when I don’t download anything or installing any new programs? Well, a folder in Windows called Winsxs could be the source of the problem. The Winsxs folder stores multiple copies of drivers in order to make multiple programs run without any compatibility problems. My own Winsxs folder is 10GB and it’s the largest folder in Windows, and it grows over time. When I look inside the folder, it seems like many of the dll files are duplicates, but they are different versions of the same file. The reason for that is that different programs use different versions to be able to run properly.

Having a large Winsxs folder is usually no problem, but if you have a laptop or an old computer with a small hard disk, then it could become a serious problem. It seems like the Winsxs folder is an unnecessary part of Windows, that just use the storage space. But don’t ever try to delete files inside the Winsxs folder because it could stop programs to start or even break Windows. You can try to clean up the Winsxs folder by using tools inside Windows 7 and Vista.
