Ccleaner allows you to backup the registry before you clean it with Ccleaner.

I don't believe that's correct (or maybe i misunderstand what you meant) Registry data includes
> Information about the Ethernet LAN driver plus
> Information about all the Ethernet connection properties

e.g. there's quite a bit of data specific to Ethernet connection properties stored within HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters alone

Oh. And as i see you and tipstir just posted re: the registry, i'll add..

For myself, the only registry cleaner i trust is CCleaner (as tipster mentioned)
> I've never had a problem with it in all the years i've been using it for registry cleanup
> And, of course, it's still wise to do a registry backup first

the point is, it's UNNECESSARY

to qualify that statement, the ROUTER has no specific settings PER brand name nor anything other than the config data
seen by IPCONFIG /ALL

Thanx
I was just thinking since my pc takes sooo long to boot and to shut down, beside uninstalling the unneeded programs, sometimes , I understand some will be left in the registry and need to delete those items. Hey, I may be a little off here, I better not mess with registry period. Thank you

You can defrag the registry also. Still to spin up the OS faster, I usually delete the current profile which after time gets really large.

Thank you. I know how to defrag the pc but how do u defrag the registry?
how do u delete profile, what is the profile.
