ReProfiler is a tool for manipulating userprofiles on Windows 2000, Server 2003, XP, Vista ,Server 2008 and Windows 7.

Reprofiler offers a quick and easy way to see which profile is associated with which user. ReProfiler is a straightforward portable application that makes it easier to fix the user profile association. Select the User Account and the Profile Folder and hit Assign to fix the issue. Every user in the Windows operating system has a user folder associated with the account name that stores computer settings and data. It can happen that the link between the user account and the user folder gets lost. Some reasons for this are hardware failures, migrating to a new computer system, username changes, joining the computer to a domain or file system permission issues.

A common problem encountered with all recent Windows versions is the unexplained loss of access to a user's data and settings. It can happen that Windows fails to recognize the user profile and folder that is linked to the user account. This has the result that a new user profile is created on the next log in which will from then on be used instead of the old one.
This can happen for a number of reasons:
* A disk error
* Joining the computer to a domain
* Disjoining the computer from a domain
* Transfer of data to a new computer
* Filesystem-permissions issues.
* A change of username.

Reprofiler lists all user accounts and profile folders upon startup. The top window lists the user accounts with information about the host, user, SID and assigned folder while the lower window lists the profile folders with links to the data folder and assigned user(s).

Reprofiler offers a quick and easy way to see which profile is associated with which user. If a problem is evident, it then provides an intuitive and straightforward means of correcting the profile ownership.

Usage:
There will be a short delay on startup as the system is scanned for useraccounts and profiles. The main window should then appear,as shown.
The upper pane shows a list of users. If the computer is a domain-member these will be subdivided into two groups, local users and domain users. For a standalone computer, there will be just the local group.
For each user, the 'Assigned Folder' indicates where, on disk, that user's profile is being stored. Typically this will be a folder within 'C:\Documents and Settings' for XP, or 'C:\Users' for Vista/7.
Scrolling to the right will reveal that user's SID, should that information be needed. (If you're not sure what a SID is, don't worry.)
The lower pane lists the subfolders found inside to profile-root folder, which as we've mentioned is typically 'C:\Documents and Settings' for XP, or 'C:\Users' for Vista/7. It then shows the users which have been assigned to each profile, in the form 'logon_domain\username' (For a standalone computer the logon_domain will be the name of the computer itself)
