registry file is still in use by other applications or services

Sister's system has many problems.  A few samplings after tons of troubleshooting already.

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.  

 1 user registry handles leaked from \Registry\User\S-1-5-21-484763869-1500820517-839522115-1004:
Process 720 (\Device\HarddiskVolume1\Windows\System32\winlogon.exe) has opened key \REGISTRY\USER\S-1-5-21-484763869-1500820517-839522115-1004

Another sampling is this:  Name resolution for the name timed out after none of the configured DNS servers responded. . .  at&t is our ISP

The content source <iehistory://{S-1-5-21-484763869-1500820517-839522115-1004}/> cannot be accessed.

Context:  Application, SystemIndex Catalog

      (HRESULT : 0x80004005) (0x80004005)

Name resolution for the name timed out after none of the configured DNS servers responded.

Someone indicated ipv6 may be problem, so changed back to ipv4.  Lost here.

This is not a new problem, and sure would like help.  Many related items such as this in Event Viewer, as well as others.

1 user registry handles leaked from ... means that the program winlogon.exe has opened a key and did not close it.

For XP there was a Microsoft tool (User Profile Hive Cleanup Service) that forced programs to close the opened keys. It's not available for Windows 7 and you'll probably find on Microsoft boards that "This behavior is by design" of the culprit program, not a bug.

As for Name resolution for the name..., it simply means that your internet connection was down at the time.

PS: starting with Windows 8.1, leaked registry handles are not warnings any more, but informations.

UPHClean which checks for leaked connections to the registry and cleans them up,
yes I used this on many XP systems and it worked to resolve slow log off brcause of some programs not releasing.
From Microsoft
What's User Profile Hive Cleanup Service
A. Frequently, a driver or application leaks registry handles, which means the driver or application opens the registry but doesn't close it. The open registry isn't a problem until you log off, when the profile of the logged-on user tries to unload the user's registry but fails because it's still in use. << read on please.

That is NOT an official Microsoft tool. It's just some junk someone coded to milk some money from the unsuspected.

Do NOT download malware on your PC just because you found it using a Google Search!

@Merete: please try (and buy) the software yourself before recommending it to innocent users. Thank you.

Once a PC has become infested with either adware or malware, the antivirus software installed will almost never detect it.  With adware (which has become prevalent) it doesn't dare call it a virus as they would lose the battle in court!
Run these, in this order:

None of them do anything until after they have scanned and they are all standalone removal tools directed at different kinds of software.
Afterwards, check the Event Viewer -> Windows Logs -> System for failed service startups that would then be residual damage caused by the bad guys.

Thanks a lot.  This is apparently an ongoing widespread issue on all 4 systems, theirs and ours.  I will return to this system tomorrow and report back, having run one other "fix" and the adwcleaner already, but not these specific 3 in that order.

Please see this other Q for the same system....  perhaps this will help
Asta CuTechnical consultant & graphic designAuthor Commented:
Sincere apologies, that was for my sister's computer.  

Sorry, Merete, the link did not work.

I am closing this and returning with a new question working only on errors, not warnings.  Thank you very much.
No worries Asta Cu

Forgot to ask how the above tools differ from others like malwarebytes?
Davis McCarnOwnerCommented:
The programs I listed are standalone detection and removal tools for different types of malware and/or adware.
Malwarebytes has; IMHO, been effectively countered by many of the newer attacks on PC's.
