Support NeoGAF

[Ghost]

My device manager looks like this:

Totally empty, showing hidden devices also reveals nothing.

It causes a few problems, I get no notification anytime i plug any USB device in (although they seem to work), i cant uninstall anything and I was just trying to install a PCI TV card only to find I cant because it doesnt recognise the hardware as installed.

Im using Service pack 2.

I googled and i googled and found nothing so now i turn to GAF for assistance.

Did you try restarting the plug & play service?

Ahh, done it...something must have overwritten the systems registry permissions


Heres the solution incase someone else has this problem in the future:

1. Go to "Start", "Run", and enter "regedt32"
2. Maximize the "HKEY_LOCAL_MACHINE" window.
3. Scroll down to "SYSTEM\CurrentControlSet\Enum"
4. With "Enum" selected click the "Security", "Permissions" menu.

Note: At this point you will probably notice there are no permissions on this key.

5. Click "Add".
6. Add the group "Everyone" and the user "SYSTEM".
7. Select "Everyone" and check "Read" ONLY!
8. Select "SYSTEM" and check "Full Control".
9. Click the "Advanced" button at the bottom of the window.
10. On the Advanced window check "Reset permissions on all child objects..."
11. Click "OK"
12. On the warning window click "Yes"
13. Close REGEDT32
