I found a WINSXS folder in my winxp home Windows folder. It has lots of subfolders though they are not very big. Everything I've found so far ties winsxs to Vista, but this isn't Vista. The latest folder has 3 .dll's is from 3 days ago, and before that there are about 30 from 5 scattered dates in 2009. They all have various numbers of .dll's in them. What is this for? Should I/can I delete all this stuff? If I delete too much of it, will the system recreate the essential parts? Can I at least delete it from the clone I want to make for the new computer?
