PC "angel". Let's send it to back to heaven
1. Open a command prompt.
2. Type: sc config pca start= disabled
(There is a space between "start=" and "disabled"- this is important!)
1. Open RegEdit
2. Navigate to HKLM\SYSTEM\CurrentControlSet\Services\PCA
3. Change the DWORD "Start" from 2 (automatic) to 4 (disabled)
Either of these should stop the service more or less immediately- this isn't normal behavior for a service, and I have to wonder if they're actually watching that part of the registry to see when someone disables it.
After this, you should be able to access files on your recovery partition. They most likely are marked with system and hidden attributes, which you can remove or just set Explorer to display.
For some extra fun, run "wordpad d:\protect.ed" and edit the warning message (it's in RTF), or open d:\desktop.ini and d:\folder.htt and have other fun.
Remember, this is your recovery software and partition- usual warnings apply. I'm not responsible for these instructions deleting your data, mangling your dog, eating the last slice of pizza, or any other heinous thing. ;)
