Windows 10: Definition of a "clean install"?

If I buy a refurbed PC with Windows 8.1 and immediately run the upgrade to Windows 10, before putting any software of mine on it, will that be what you'd call a "clean install" of Windows 10?

Then I transfer my stuff from the old Windows 10 upgraded PC to it?

:)

 

Windows Defender won't update (error 0x80070643)

I deactivated Windows Defender and now I was able to install The olhei updates. Hope they fix it soon

 

getting Error 0x80070643 but have NO other anti-virus software installed

It seems every one that Clean install Windows 10 since 26 October have this issue

cause of this issue is NIS definition, Windows Defender can not install NIS definition

NIS??

 

A clean install would be installing Windows from a USB Flash Drive, DVD, or from the computers own Recovery Partition (ie) set back to factory settings. Eliminating the previous owners personal files and software problems. Then, if you installed Windows 8.1, updating to Windows 10 then restoring your personal files.

 

First off, in that situation the install of Win10 is no longer available as free. It's possible that a refurbished PC [Desktop or Notebook] will likely have the same software on it as when it was new. A "clean install" means everything is wiped from the drive before installing the Operating System.
Secondly, you can move/copy your "stuff" to wherever but any Windows-based programs would have to be installed, create their icons, add to the Start menu, copy support files to the proper place and create their Registry entries so Windows knows how to run them.

 

This is a factory refurb, which I understand comes with the option to upgrade from 8.1 to 10. So it won't have any software on it to worry about, to begin with. So then I'm thinking of upgrading to 10. THEN it would be pretty much a clean install at that point, right? So I could then copy programs over from her old PC which has had the upgrade to 10 already? Is that how it can work?

Or what you appear to be saying is that I'd have to install the stuff on the new PC after upgrading to Windows 10, then just copy her data over.

 

This still works!

Windows 10 free upgrade is still available using Windows 7 and 8 keys

 

It may also work with a factory refurbed PC like this one, but even if it doesn't, it's no big deal.

 

A clean install would be to upgrade to Windows 10 in order to acquire the license, then download the Windows 10 install media, wipe the hard drive and install Windows 10 from scratch. Upgrading from one Windows version to another is never a clean install.

 

You do not wipe the hard drive before you clean install W10, with Windows open it is not possible.

Its a bit like trying to remove a chair whilst sitting on it.

The install media removes everything during a clean installation.

 

Of course you can do that during the installation process. I always remove all partitions or at least format them and start from scratch.
