Here we go
Boot into MiniXP and download this file
to the desktop.
Double click the file to run it.
It will first make backups of several files, and if successful, will pause and instruct you to load Registry Editor PE.
If unsuccessful, it will exit and open a log that needs to be posted here.
It is not necessary to load any user hives.
Once Registry Editor PE is fully loaded and the registry editor opens, minimize it to the taskbar. Do NOT close the editor!
Press any key to allow the tool to continue running (it will ask you again if you're sure).
When complete, a log will open.
Post it's contents here.
Please do not attempt to start the computer normally until I've responded to the log.
Now, so that you know what we're doing;
The tool will configure your system to do a diagnostic startup.
In doing so, it's necessary to re-write the system.ini and win.ini files.
It is also necessary to disable most services and startup items.
The tool does this by creating the necessary registry keys to re-enable them later, and modifying the Start value of the associated registry values for those services.
As mentioned above, backups will first be made of all files and registry hives.
