Windows 7: Need help modifying Control Set to Last Known Good Configuration

Windows 7 Ultimate 64 bit
Need help modifying Control Set to Last Known Good Configuration

I'm running Windows 7 64bit Ultimate and experiencing registry issues. I am only able to boot to Last Known Good Configuration ...otherwise experience BSOD. The blue screen boot issue has been going on for a while but I now need to be able to reboot so am seeking help (hoping to avoid an installation repair or complete reinstall of Windows).

I was planning to follow the instructions from Microsoft support for restoring a previous control set: Restoring Previous ControlSet After Using LastKnownGood ...however, it my registry looks a bit different and I'd prefer to check with someone who understands more than I do before I proceed.

Instructions from Microsoft :
1. Go to HKEY_LOCAL_MACHINE/SYSTEM/Select, which will display the following parameters (your data field may vary depending on the ControlSet being used):


However... my registry files look different:


Considering the difference in my control set, I'm a bit confused regarding how to follow the rest of the instructions to fit the control set on my system.

Here are the remaining instructions from micorosoft:

2. Look in ControlSet001 through ControlSet003 to find the ControlSet that should be restored.
Change the data in the following Registry key:

Current:REG_DWORD:0x3 and Default:REG_DWORD:0

to the appropriate ControlSet. For Example:

Change the LastKnownGood:REG_DWORD:0x2 to the previous Current data. For example:


3. Exit Regedt32 and reboot the server.

I know it should be pretty straight forward to modify these instructions for my system, but I get nervous when it comes to modifying registry files. Can anyone help with providing explicit directions for me?

Hello and welcome :) .
The instructions you posted are intended for very old server releases of Windows so they are not applicable
to Windows 7 I presume.


  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Advanced Server
  • Microsoft Windows 2000 Professional Edition
  • Microsoft Windows NT Workstation 3.5
  • Microsoft Windows NT Workstation 3.51
  • Microsoft Windows NT Workstation 4.0 Developer Edition
  • Microsoft Windows NT Server 3.5
  • Microsoft Windows NT Server 3.51
  • Microsoft Windows NT Server 4.0 Standard Edition
Why won't you follow the Blue Screen of Death (BSOD) Posting Instructions and we'll go from there :) .
BTW have you tried system restore?

Two days ago in the evening, my computer that always used network 2 made a network 3 that included the neighbor's computer and there was extreme lag. Even after they're gone, there's still some lag, and whether network 2 or 3 is active varies per start up. The way the network looks keeps...
