I have been struggling getting some 3G USB modems and some other hardware to work and in the process I have managed to get a lot of unnecessary and just plain wrong drivers installed. This is causing my system and other hardware to work incorrectly. I would like to remove all the drivers on this system and have windows reinstall all the default drivers.

Can I do this with a Windows 7 repair install or how else can I get rid off all the current drivers.

I would recommend that you do a clean reinstall of Windows 7, that way you can wipe all of the old drivers, and Windows 7 will automatically reinstall the default drivers needed (for the most part).

Obviously, it is not possible to remove all of the drivers in an operating system, because it will break the OS permanently, thus a clean reinstall is pretty much the only way to go...

Thanks for the answer. I best way I think is doing an repair install. – Jake Apr 16 '11 at 8:50

You can use sysprep tool for that. Just run it from c:\windows\system32\sysprep\sysprep.exe, check Generalize and hit OK

While this answer could be correct, a much better answer would be if you could include how you would use sysprep to do that. – Scott Chamberlain Feb 9 '14 at 15:36

That would be good to put in your answer, not a comment. – Scott Chamberlain Feb 9 '14 at 16:22
@ScottChamberlain done – Poma Feb 10 '14 at 7:15
Shouldn't this only be run from a clean windows install? – Jack Dec 9 '14 at 23:19

Removing ALL drivers will damage windows and make your life horrible! Your are better off selectively removing the drivers.

Boot from Windows 7 DVD Select Repair and command prompt

Lists all drivers

Dism /Image:C:\test\offline /Get-Drivers 

feed the list one at a time into the remove command below. It is only necessary to mount once, not once per driver.

Dism /Mount-Image /ImageFile:C:\test\images\install.wim /Name:"Windows 7 HomeBasic" /MountDir:C:\test\offline

Remove a specific driver from the image. Multiple drivers can be removed on one command line. For example, type:

Dism /Image:C:\test\offline /Remove-Driver /Driver:OEM1.inf /Driver:OEM2.inf

Removing a boot-critical driver package can make the offline Windows image unbootable

Adding drivers also has a command

Dism /Image:C:\test\offline /Add-Driver /Driver:C:\drivers\mydriver.inf /ForceUnsigned

Dism /Image:C:\test\offline /Add-Driver /Driver:c:\drivers /Recurse
