I believe that it stands for windows on window (wow) and runs when you have 16 bit applications running on the server. Maybe someone else can tell you how to stop it.

WOW does stand for Windows on Windows and is the 16-bit Windows subsystem that runs inside of a Virtual DOS Machine (VDM). It is true that you have a 16-bit Windows application starting up and these applications run incredibly slow on NT - especially if you have an optimized 32-bit processor such as a Pentium Pro or Pentium II.

To stop it, you need to find out what 16-bit application is running, and where it is starting from. If it is not in the obvious Startup folder, look in the registry under the following key

HKEY_LOCALMACHINE -> Software -> Microsoft -> Windows -> Run

Remove the offending application either by removing the shortcut from the startup folder or by deleting the subkey from the registry, whichever is appropriate.

CAUTION: If you are not familiar with editting the registry on NT, please ask for more help before proceeding! One wrong move in there and whoops, you'll be installing NT again.

Hello mbreuker !

Could you please answer the question, so that I'm able to forward the points
to you.

Somehow GetRight didn't work well any more. After reinstallation it is fine now.
