I thought you'd tried Windows System Restore but on rereading your post it appears that you were talking about restoring your own backup.

If system restore doesn't help then read the following which could help you as it gets deeper into Windows configuration. But before starting have a complete backup you can easily restore. Make sure that you have a system restore point before any change. Also don't do anything that you cannot reverse easily. For example, instead of deleting files simply rename them so you can rename them back if you need to.

I asked questions as you didn't provide enough information for me to eliminate some options.

Uninstalling means physically removing the files from the disk by deleting them. I asked you to clarify this because it is different than disabling a feature. If Windows is only disabling the feature then turning it back on will continue to use the same files and you will have the same situation.

I would try this myself but I'm in the middle of configuring my systems and can't test on my Windows 7 system.

WMC comes with that edition so licensing shouldn't be the problem.

What is the brand and name of the scanner?
What is the device name in Device Manager? To display the scanner driver, you will probably need to select View | Show hidden devices.
What are the hardware ID(s), Driver Key and Inf name?
You will find them in Device Manager | select device name and right-click to view Properties | Details tab
Now set Property to Hardware ID, Driver Key and Inf name and copy each value.

Here's examples for a video camera:
  • Hardware IDs = USB\VID_046D&PID_08AF&REV_0100 and USB\VID_046D&PID_08AF
    These can be used to search for more information on the Web.
  • Driver key = {6bdd1fc6-810f-11d0-bec7-08002be2092f}\0000
    The first part of the key before the "\" can be used to find registry entries which can be deleted.
  • Inf name = oem87.inf
    This can be used to locate the .INF file on disk so it can be deleted if necessary. They are usually in the Windows\Inf folder.

Windows will reinstall drivers automatically if it finds any plug and play hardware when it restarts. Windows can also keeps device's installed even if the device is no longer connected. Background processes or services can also "recreate" the entries.

To check on services, go to Start menu | Run | type in "services.msc". Look down the list of services and see if any are running that have the brand name or model of the scanner, include "scan" or include "TWAIN" which is a scanner software interface. You could disable it or ask here if you're not sure.

FYI, while you are looking at services you can also see if "Media Center XXXXXX" and "Windows Media XXXXXX" services are running.

Whether you find any relevant services to disable or not, you should use Regedit in Safe Mode to remove device driver entries. Safe Mode won't load most drivers which makes it easier to delete their registry entries and files.

Safe Mode is selected by starting your computer then holding down F8 so Windows displays the recovery menu then select Safe Mode.

I suggested this as a last resort because it is a way of determining what the settings are when Windows media Center is correctly installed. If you can't work out what is wrong then seeing what does work can help to repair your setup.
