Shell is the Explorer.exe shell (core component of Windows GUI) As far as uploading the trace file..Those exceed 100MB so it is not feasable to upload it.
I know you are trying to avoid it, but reinstalling Windows is going to be your best bet. You are going to spend more time on slows load & trying to figure out what is going on, than it would take to install a clean version that you know is in perfect working order.
I would suggest you create at least 2 partitions. 1 for Windows, etc, and one to store drivers, backups of documents, favorites, mail files...etc in the event something ever goes wrong.
I have my system partitioned into 3 drives
C:-OS & Apps
D:-Games & Media
E:-Utilities, backups, drivers, crap I download for installation off the internet.
as you know, my boot times run around 19 seconds with Zone alarm & all my other aps running . As lolng as you can get something that boots under 30 seconds you are good to go.
