Hi, I have 2 issues I need help with.

Firstly - They say curiosity killed the cat well it has killed my "open
with" option in the right click context menu. I have managed to restore the
option but it has no function.

No matter what file type i click it is there but not options. On some files
there is a sub menu link to it but again this has no function. If i double
click a file with an unknown association then I get the open with window
allowing me to open the file with a list of programs, however the "Always
open with this program" check box is greyed out.

Secondly - I have also lost the "Run as administrator" option. I know this
can be done by entering the properties of the program but it has been a very
useful option in these early days of me using vista.

Can anyone help me restore the functionallity of the "Context menu"

Many thanks.
