I have the same problem as in the topic in the thread:
The file in my case are:
C:\Windows\Registration\javaxml.dll being used by the winlogon.exe
C:\System32\req.dat beinf used by the explorer.exe and winlogon.exe
When I start in safe mode, my explorer dies within 2 mins, so I have to rely on command line; but I can start processes if I am quick.
I somehow managed to delete the the req.dat but now what happens is that just after the shutdown process, the computer shows me a blue memory error screen and then I have shut the power off manually.
If you would require more specifics please, just tell me.
Thanks a lot.
