If you're troubleshooting a desktop system on a network where roaming profiles are being used, you may want to temporarily disable roaming profiles on the machine and use a locally cached profile instead. That way when you reboot the machine or log off and on, you won't end up having the roaming profile overwrite any diagnostic changes you've been making to the machine while troubleshooting.
To change from using roaming profiles to a locally cached profile, open System in Control Panel, switch to the Advanced tab, click Settings under User Profiles, click the Change Type button, and click Local Profile.
