can't right click desktop

i used a desktop right click option to hide my desktop icons
i did this over 5 months ago and now i want them back
but i can't right click my desktop now
and can't seem to find that option anywhere else in windows 7
and system restore is turned off don't want to lose any programs or games i've installed since then ie the 20 plus games since then
other than that my system is running pretty good
is there a way to restore all windows setting to defaults without losing programs

Look here in the registry
type regedit into the search box and hit enter
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
for a value in the right pane called "NoViewContextMenu"
If present change the value to "0"
reboot
Before editing the registry
Back it up
Create a restore point
Export the key for safe keeping

disregard i've fixed it
i used uniblue tweak program to do it
not right click
and forgot about the program

Ah, another tweaking program. Thanks for the followup and glad to hear that you were able to resolve your problem.
