Change registry key from another PC

[bartNL]

Hi,

Soo.. I just disabled the RPC service.(call me stupid, i know. i didn't do some research before doing this) But now my pc doesn't boot properly anymore.
I.e. it shows a black screen when the login screen should appear.
I guess i have to revert the made changes by tweaking the registry from another pc.
I believe the responsible key is saved in system.dat, located in %windir%\system32\config\.

I almost know the procedure which has to be followed to achieve this, my question is:
do i just have to load the system.dat file, or do i have to add/change other components as well?
(e.g. backup versions from the file) And when i'm done, do i just have to replace the original system.dat by the reverted system.dat, or is there a special procedure for doing this? I'd rather not mess things up any further.
Thanks and greetings.

Silly question but, have you tried safemode?

I think i can't access safe mode, at least not with much effort. Accessing bios, safe modes etc is a pain in the *ss in win8 machines.. At least in my case. But i suppose you would suggest booting in safe mode and then editing the registry, it's not a bad idea. But considering the nature of the cause of windows not booting properly, i fear the safe mode won't work either.
Thanks for your help.

Safe Mode might not work, but you ought to try it. It may be your only chance to fix the problem.

Okay, so i fixed it, I thought it'd post it, maybe other ppl with same problem can benefit from this. Luckily it was indeed as simple as i thought. I have two laptops so i had to hook the ssd from the broken one via a SATA>USB cable to the working one. Loaded the registry-tree and reverted the value responsibe for rpc back from 4(disabled) to 2(automatic). Shove the ssd back into it's original place and booted up the machine. Everythings working again..
