Corrupt Windows XP Profile

Event Viewer Errors:

Windows cannot load the locally stored profile. Possible causes of this error include insufficient security rights or a corrupt local profile. If this problem persists, contact your network administrator.

Source: Userenv
Event ID: 1511

Windows cannot find the local profile and is logging you on with a temporary profile. Changes you make to this profile will be lost when you log off.

Login - create new profile and copy over profile data - from old data - DO NOT copy corrupt profile into new profile.

Sometimes small problems can be fixed by using this tool - to fix corruptions:

Download and use the "User Profile Hive Cleanup Service"- this will install itself as a service and monitors the profile - if it finds that the data in memory is not in sync with the profile it will flush the data in memory to disc - preventing "lost" data when you reboot or logoff - this is the only workaround to the problem in XP.
