Restore Point doesn't fix

[nipadweller]

Can you hear me now? NO ! No audio devices Code 39
9 items in yellow in DevMgr plus HP2350 scanner when turned on.
Windows XP Serv Pk3
Earlier Restore Points even from months ago do not change these settings? Why is that? How do I fix this?

Try to rename the key in regedit and let windows redirect automatically see if it helps:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}
