windows XP not showing anything in the device manager?

[Jasonholt]

My wife's HP with windows XP is not showing anything in the device manager. It doesn't even show the computer name.

I am also having trouble getting my wireless connection to work.

That may cause WIndows update you recently installed.
Uninstall it, if you have problem after and restart.
And
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
