Windows Updates Leftover Files: filterpipelineprintproc.dll, msxpsdrv.cat, mxspsinc.ppd, xpssvcs.dll, etc.
Recently when running some Microsoft updates on my Windows XP laptop, including a .xNET framework update, I noticed a couple odd looking folders located in the top of the C: directory afterwards. The .NET framework had various issues during install including actual fails a couple times. I didn’t notice the odd looking folders until a week or so after running the upgrades or updates but at first I wasn’t exactly sure what to do with them.
After a bit of research it looks like the files were supposed to be cleaned up by the update process however they were not cleared out and deleted probably because of the fact that there were issues. Below is a list of some of the directories and files that were leftover after running the update process.
