OK now you click start on your task bar

a. Click on Start --> Run --> and type in 'regedt32' followed by the enter key
b. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or clicking the "+" next to it.)
c. Expand the "SYSTEM" Key
d. Expand the "CurrentControlSet" Key
e. Expand the "Control" Key
f. Expand the "Class" Key
g. Look for a key containing the following string of letter and numbers:
h. Highlight this key by left clicking once on it
i. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these delete them by right clicking on them and choosing "delete"
j. Exit the registry by clicking on the "X" in the top right hand corner of the screen.

then restart your computer

I successfully located 'UpperFilters' but it would not let me delete the value. As for 'LowerFilters', that was not in the folder specified. please help, i would appreciate it very much
