Windows 7: Does a reinstall of win 7 set registry to factory settings?

I want to remove all my registry errors and was wondering if I reinstall windows completely does that resest all of the registry?

Hi and welcome to Seven Forums.

Yes you'll have a new Registry.
First you should back up your Data that you want to keep.

How are you getting registry errors?

It depends how you are re-installing.

You mention factory settings so I assume it's a factory-built computer?

If you carry out a retore to factory state the system registry will revert to the factory-installed database.

If you carry out a clean install your registry will revert to that of a Windows 7 re-install, which will be different to a factory-restore registry.

Rather than a re-install, you might want to consider a repair install, which will leave your personal files and applications intact.

Whichever road you take, do make sure you've backed up anything important first.

Human error.
I was attempting to set up a c: boot drive (ssd) with a HDD 2ndary
I either typed or deleted a registry entry by mistake.
