Somewhat the same problem
Hey,
I joined this forum just because I had a similar problem although not as sever as what happened to you, and could not come up with any other references on the problem. I have 7 beta on a hp pavilion laptop I don't remember what build but whatever then just recently when I clicked on my computer link it would take a increasingly long time to scan the contents and then would freeze I could close the window but if I then tried to open any type of explorer window it would just be a blank page, any other type of window was fine (help type windows, internet windows, text files, bla bla ). I tried to restart explorer by way of task manager end process start new task, but then any explorer window would come back with the remote process failed. When I looked at services my rcp service was stopped but all options to restart service was grayed out. when the computer first boots the service is running and the same problem occurs after about two links into a explorer window. It got so bad that it would take 15-20 minutes to boot. I tried both windows bit defender as well as avast anti-virus both scans came up clean. I had heard of a bug that affects the RCP. I also tried msconfig selective services and diagnostic boot no affect on either case. I did notice a weird hidden ini config file on my desktop I know there's usually one on there but had never noticed two as with the case now I don't remember exactly but some resource root text file. I finely had to do a week old restore point, it seems to have done the trick, that second desktop ini file is also gone. I installed panda anti-virus after the restore, it did fine one infected file in the recycle bin but it was just a random numbered file so I don't know what it was from. Anyway hope this can help and good luck.
