How to fix corrupt or unavailable user profiles

Now this isn’t a problem I encounter to often, but sometimes when you have
several accounts on the one machine, trouble can occur with the various different profiles and they may become corrupt. It could be as a result of
somebody deleting an important file, a virus or malware infection or a system
crash, not to mention the mysterious “it was perfectly fine when I used it”
answer that you can get from little brothers and sisters.
Anyway enough of the blame game, how can you actually fix a corrupt
profile? Well thankfully you don’t have to go digging through the registry
and trying to restore from back ups etc… there’s a handy little program
floating around called Reprofiler, and they might just save the day for you.
If you’re experiencing errors such as Windows no longer recognizing the
profile that belongs to a certain user (it creates a new empty profile when
you log on and continues to use it instead of your old one) or if you simply
can’t log on at all then you need to give this a go.
You need to log onto another user account and run Reprofiler. Simply select
a user account and you will be able to see the user name, domain, SID and
profile path. It will then notify you as to whether or not it’s logged on or not
and gives you the option to log it off before you perform any actions on it.
Then you will be able to use detach to disconnect a profile from a data folder
or assign to re-attach. If you’re getting a message when you log in that
Windows was unable to load your profile due to some form of error,
ReProfiler’s assign button could very well provide an automated fix for you,
with very little input on your behalf.
