Rollback Driver from Windows Command Prompt Using Repair Disc – How to

command linedevice managerdriversrepairwindows 7

I think I found the problem to my Windows 7 Reboot Loop when it goes to configure from a Windows Update (it stops at 32%). Even when I choose Safe Mode which says it is reverting the Windows Updates.

I'm not 100% sure but it could be my UPEK Fingerprint driver. There was a recent release of an update for it, and Windows Repair Disc did a scan and, though it couldn't fix the issue, the results stated that a driver error was not letting windows startup.

So, once I'm in the Windows (R) aka Windows Repair I have the option to load up Command Prompt. I can then access my Windows Drive which for some reason got assigned to D: instead of C: … my question is:

Normally if I want to remove a driver I go to Start>Control Panel>System, click on the device and remove it (the driver get's removed). What is the equivalency of this in the Command Prompt?

Driver Information is stored in the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services

You could use the reg command:

Example the VGA Driver information is in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\vga

But you will have to know the folder name of the driver. Once you find the folder you would have to change the REG_DWORD named "Start" to 4.

Start=4 is disabled Start=2 is Automatic Start=3 is Manual Start=0 is Boot Start=1 is System
