but have a look at this;
In particular the Registry edit option.
It may be that you have to reboot after uninstalling CSNW before the change is accepted.
I wanted to uninstall client services for netware so I would be able to use the welcome screen. I went to uninstall it and the computer completely froze up. So I restarted and went to try again, but it wasn't listed on the properties window, so I thought that it was uninstalled. But then when I went to change the welcome screen it said that it still couldn't because client services for netware was uninstalled. So I went and re-installed client services for netware so I could uninstall it again, but every time I try to uninstall it the computer completely freezes up. Help?
