Unregister Windows Service pg_ctl error

When I try to unregister the windows service I get an error like:

C:\Program Files\PostgreSQL\8.1\bin>pg_ctl.exe unregister -N
"pgsql-8.1"
pg_ctl: could not open service manager

This is on Windows XP and the logged user is postgres

You need administrative privileges to unregister a service. Can't run it
as user postgres.

I did the same under "Administrator" but then I get an access violation
error like:

Unhandled exception at 0x77c478c0 in pg_ctl.exe: 0xC0000005: Access
violation reading location 0x00000000.

What am I dong wrong?

That's the bug I sent in a patch for just now,that Peter has applied.

The workaround until the next release is out is to specify the data
directory when you do unregister. E.g.
pg_ctl -D ../data unregister

You shouldn't need that, but due to the bug you get a crash if you
don't...

Thank you :)
