Thx for the update MrG. Used the program and then tracked what was cleaned in registry on WinXP SP3. It does not appear that the MUICache Bags or MRU Bags are fully cleaned & removed. I had over 300 "bags" and half had valid *readable* text data. Not a bug, but I think a needed minor fix. Great program. made my donation under another name a few months ago. Take care.
