A MessageBox typically won't show from a Service - it's running with a
different account and probably wasn't installed to Interact with Desktop.
Your Service thread might just be crashing too if those keys/data items are
missing - I think the process still stays running so it looks like a hang.

Chakkaradeep,

What is the account that the service is running under? Is it possible
that the account doesn't have rights to the registry? If you set the
service up to run under an admin account, does it work?

Your service runs in a secured non interactive non visible
desktop/winstation. Whenever you execute MessageBox.Show the MessageBox is
not visible and no-one can press the OK button and your service appears to
hang.
Remove the MessageBox.Show and try again.

What exactly is not working, any error code exceptions? ( you don't seem to
need try/catch blocks)
Is the registry path correct?

Time to attach a debugger and step through your code I'm affraid, if you
can't supply us more info.
