I'm getting a message that my hard drive is too full and I need to remove some programs before I can do a defrag. My Windows folder on the C: drive is 7.2 GB in size. There are over 200 folders in the Windows folder that are named some variation of $NtUninstallKB941569$.
These folders each contain a folder called spuninst, and some .dll, .sys, .ax, or .exe files. What are these $NtUninstallKB941569$ folders, and can I safely delete them?
