i m describing the trick again...
1- Goto Run (in start menu)
2- type "regedit" & ok
3- in the left pan just click on the "+" sign to expand the list
goto this path by expanding the list one bye one
4- now at this point look in the right side pan
there is a entry named.. "Checked value"
double click on it
5- now change this "Checked value" to 1
i think this will be enough.....it works 100%...
the people who cant open regedit...i will soon post simple registry that can be patched directly...to get rid of this problem
