It is also quite normal for the Windows folder to grow over time as updates and programs get installed onto the system. The fact is that there really is no safe way to clean out stuff from the Windows folder beyond what Disk Cleanup can do. There used to be a program by Microsoft called miszap.exe that could clean out orphaned files from here, but there were issues and it is no longer supported. The recommendation of running Disk Cleanup in the other answer are worth a try, but I suspect winsxs is the main cause of your large Windows folder.Īnother folder that can grow big is the Windows\Installer folder, a protected system folder that contains repair and uninstall information for the programs and updates you've installed. The cause is winsxs, and the details are described in this blog-post.įor comparison my Windows folder is 29GB, a bit bigger than yours. This is normal behavior of Vista/7 and there isn't really much you can do about it. The Windows folder may start out in the 6-8GB range bbut it will grow larger over time.
