Super Duper Slow Shut Down.

Hi All, I've just got this new computer and got updates etc. Now it's super slow shutting down. Takes about approx 2 - 3 mins. I did what other's have taught to change registry etc. still no help. This is event log i got:
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 -
2 user registry handles leaked from \Registry\User\S-1-5-21-1207459158-710461736-3641573548-1161_Classes:

I did all that, didn't help.

Try uninstalling unused programs and deletes files on your Anti-Virus quarantine.
