how can I recover the registry?

My computer got the error, I don't know why but maybe it's because I ran a registry cleaner or the computer crash time ago.
Now when I start the computer there are some dialog says that there are some problems on the reg and asks to restore the default value, and it keeps showing that dialog everytime I start the computer.
I checked the event viewer, only seen the warning something like this:
"
Windows detected your registry file is still in use by other applications or services. The file will be unloaded now. The applications or services that hold your registry file may not function properly afterwards.
DETAIL -
1 user registry handles leaked from \Registry\User\S-1-5-21-1216382924-1572877739-2728514917-1013_Classes:

"
How can I solve this problems? It doesn't affect to the performance of the computer but gives some troubles.
Thank you very much.

Hi Independentvn,

You can do a System Restore using a restore point dated before this problem started to fix this problem. This tutorial will show you how to do a System Restore if needed.

Unfortunately, there is no any restore point being created before hand. Maybe I have to accept that trouble, it's not a big problems and reinstall everything waste me so much time.
Thanks for your reply.

Your welcome Independentvn,

I'm sorry to hear that. You might check with the registry cleaning program to see if it may have a undo option to restore the reg files it deletes.

Another option is to do a Repair install. However, with SP1 installed it can take a while to do since you will need to create a slipstream DVD to use first since the normal method will not work anymore with SP1 installed.

Repair Install For Vista

I guess this comes from Defender.
You may ignore the warnings or disable Defender. (check if you have still the error when defender is disabled)
I remember a Microsoft tool working with XP (uphclean) have a look if they have a new version working with Vista.

thanks everyone!
Sorry for my late reply, I've just so busied in this week.
I solved my problems.
Just active the Administrator account, backup other account's data, delete them all and created a new one.
The vista stores the user profiles in registry, and whenever a new account is created, it uses the same setting for non-administrator account. So if we don't delete it first, the problems still exist.
I learned a new little lesson.
Thank you

Independentvn,

Glad to hear that you got your problem sorted. Thank you for the feedback.
