How do I change users?

How do I change how users log on and off windows XP Laptop?

• Randomly one day when I started up my laptop, instead of the usual welcome screen the school/professional version popped up and I don't know why. When I try to change the way users log on and off in the control panel a message saying "Client Services for NetWare has disabled the Welcome screen and Faster User Switching. To restore these features, you must uninstall Client Services for NetWare." when I deleted the Client Services for NetWare, the same message still popped up. It doesn't let me do anything. How do I switch it back to the way it was before?? Thank You for any help

• Answer:

  Go to your network connection, right click it and select properties, then select client for netware and remove it. Also any other netware related services. You or somebody else on the machine must have installed this, it NEVER installs except when required by the user. It serves NO useful purpose on a Windows machine, it only has any use when connecting to a Netware server.
