Windows 7: Need Help Please

Windows 7 Professional
Need Help Please

I have Windows 7 Professional on a Dell Alienware laptop. Everything is up to date.

Recently I purchased Fallout 3 from Steam. The game had been patched but with that patch meant it was unable to run with 4 cores and what id did was cause the game to freeze. So I went online and found help they had me change in the Fallout.ini the line 'bUseThreadedAI=0' to 'bUseThreadedAI=1' and add a line under it 'iNumHWThreads=2' This limited the game to 2 cores and prevented the engine bug from causing the game to freeze.

Fallout worked like a charm.

Then I went back to wanting to play other games, all of which I found were lagging.

What I did was change something in my computer registry that limits my laptop to two cores while still trying to run with 4 threads. I went and changed the .ini file back to no avail.

How do I change this back?

I called everyone from Microsoft to Alienware to Bethesda and found no help!

Use System Restore to go back to a date before you made the change.

Is it possible to do it without using system restore?

What is the problem with System Restore?

Win7 needs no tweaking as it will always come back to bite you just like it has.

Have you backed up a Win7 System Image, which is built into Win7?

You can try running SFC /SCANNOW Command - System File Checker

The last resort before reinstall is Repair Install

Well its not a problem and more, I have a lot of games and stuff I've downloaded and would prefer to use system restore as a last option.

No, I've never used System Image. What will running sfc-scannow-command do?

Figure out which Restore point is just after when you made the changes, then let it scan for affected programs so you know what will have to be reinstalled. Then make your decision whether to restore.

System File Checker checks the integrity of system files against clean copies and repairs/replaces if necessary.

Repair Install holds everything in place while reinstalling the OS under it. Most harmful tweaks will not carry over.

Be sure to run the command prompt which is located in the accessories area for all programs as Administrator. Or it will not work. Left click and select run as administrator.

While an SFC Scan is not going to hurt

If the problem is indeed in the registry and you do not remember the changes you made, then the only resort is,,,,

a.) System Restore

b.) Nuke and Reload
