Hi guys I'm having the same problem, I have followed the steps given:
When I get to Then find
Start the Run Command Prompt
Type in "regedit" without the parrenthesis then click ok
Go to HKEY_LOCAL_MACHINE
Then SYSTEM
Then CURRENT CONTROL SET
Then CONTROL
Then CLASS
Then find {4D36E965-E325-11CE-BFC1-08002BE10318}
The whole thing looks like this:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
Then delete the upper and lower filters....
RESTART YOUR COMPUTER THEN THERE YA GO!!!! HOPE THIS HELPS
When I get to Then find
There are no Upper or Lower filters{4D36E965-E325-11CE-BFC1-08002BE10318}
