How do I restore windows 7 default drivers & registry? (Without a reinstall... )

I have windows 7 enterprise 64 bit.  About a week ago it started to act odd.  USB devices that used to work fine stopped working.

Plugging any device into a usb port leads to drivers not loaded / found.

These are all common devices that have no manufacturer drivers and used to work.

What I didn't realize at the time was that if I unplugged a USB device that was working and plugged it back in it would no longer work!!!

I have found 2 ancient (CrappY) USB devices that do work.  key board & nearly worn out Trackball.

I am suspecting that perfect registry optimizer has over time ruined my registry.  It would often lock up and I would just kill it :(

Is there any method to "reset" Win 7 to replace the drivers and registries to "factory" setting without a full re-image?

Like a dummy I have no working restore point and hate the idea of rebuilding the whole thing.....

If you have no working restore points I would suggest doing a Last known good configuration from boot up.

If you booted successfully after the registry damage, the Last Known Good is not going to help.

You may try the Perfect Registry Optimizer's "Restore" feature.

If a protected windows file is damaged, you could find out by running
SFC /VERIFYONLY
(in an elevated command prompt)
SFC /SCANNOW
to repair.

Otherwise it's a reinstall.
There is no way to recreate "default registry" beside the Restore feature in your software.

Was there a reason to run the Registry Optimiser?

Reason to run it.... hmmmm.

I have been known to install and uninstall a lot of things so the registry does get a bit messy.

However, I see no good reason (in hindsight) to have it run at each boot.....

I did use the restore feature back to the first time it had been run.   no luck there....

I will see about the SFC stuff and get back to you, THANKS!
SFC finds nothing out of order....

Reinstall looms in the near future.....

OK, so I do not see Windows 7 Enterprise listed on the links for the direct download ISO that the sevenfourms article points to.

The DVD"s my "Enterprise" has may not play as nicely as the article shows.

I am not having any problems with USB storage.  only because I have not got any....

As of now, in safe mode only a PS/2 kbd works and a few old USB mice.
If I plug anything in it does not find a driver.

I will try the above method on USB stuff.
Well, I thought I should update everyone.

None of the suggestions worked for me.  I even downloaded new chipset drivers and then unistalled the chipset from Device Manager and had it delete the old drivers.

After the reboot process and installing all new chipset drivers it still didn't work with the most rudimentary of USB devices....

I ended up doing a fresh Win 7 Enterprise install.  That fixed it.  I may never know what killed it but I am not reinstalling any of the tools that "optimize" registries or drivers.....
I think the "upgrade solution may have worked if I wasn't on Enterprise OS already"
a fresh install is the only guaranteed solution
