0 user registry handles leaked ?

OK Ive gotten a little bit further with this not stopped it but found what i hope to be cause except not sure if i can delete the file without losing stuff.


Ok so what i did was i set up another user account as it wasn't happening on a new one and kept copying folder by folder of my other user from the APPDATA folder till it happened it was a bit long and tedious but in the end it turned out to be



appdata/local/microsoft/windows/usrclass.dat


The other usrclass files in this folder didn't make a difference only this one seemed to bring it back on other user and when swapped back with it went away again.


So i guess question is could i delete this on the one that is going wrong and have no adverse effects? what does it actually do?



I have read a little saying it keeps user preferences etc in but not sure what or even if i can repair it as there's obviously something in it that is causing the error.

Hi Bugsy,

Once you have created that new User profile, bug free - just remove the offending one

User Account - Delete


You have now reicieved Sherlock Holmes's hat

Yeah i know i can do that but i didnt want to lose how i had customized etc on other profile will mean i need to set up everything again in terms of personalisations would the usrclass.dat recreate if i deleted it?


Is there anyway to look into the usrclass.dat file.

The best way to find out is to rename that .dat file to something like usrclassold.dat and reboot. You might want to set a system recovery restore point before doing so in case there's a boot problem. On the other hand, if you ran into a boot problem, you could go into safe mode and change the folder name back to the original.

Thanks for all your help everyone hopefully will be the fix below but wont know till tested for a while.


I have renamed old one too usrclass.old via another account i created and then logged back in to which it recreated the file and i dont have the error anymore the question will be if i see any changes to which the file would of stored info such as personalisations etc. Not noticed anything major as yet as ive even got all file associations same which i thought may be one of things that may of reset.

Will let you all know how i get on over coming days/weeks and if there isn't anything then its finally solved well in terms of fixing it but what caused it i will never know at present.

Great! Fingers crossed that everything will be okay.

Right to update you all as its been over a week its not returned so i have solved this problem. I havent noticed anything in terms of personalisations that have changed but may vary for others.

So for those having similar problem here is what i did so that i could continue to use same user account without doing a new one.

1. Create another local user account i named one Temp
2. Log on to the new account you just created
3. Go to c:/users/your username that has error/appdata/local/microsoft/windows/
4. Rename usrclass.dat to usrclass.old
5. Reboot and log on as the user you had error with.
6. Check event log for the error if gone and everything ok with account delete temp user you created.


Note: You may get the odd new error in event log i think this is due to creating new usrclass.dat but they will be one offs and not on each boot.

Also this may cause some lost in personalisations for the user account for some however in my case i didn't notice any changes other than the error had gone. But i must warn you as we all have different setups make sure you don't just delete the file rename it to .old as backup just in case.

Thanks to all those helping on here was a tedious job to try and find but got there in the end and hopefully will help others who have this problem as its a very rare occurrence to have the 0 handles leak.
