Most of us who have dealt with upgrades in the past know how cumbersome they can be, so it's always been best to do a clean install. Backup your data and settings and you'll be fine... it's best for both performance and clutter to do a clean install.

A surprisingly large number of people seem to be struggling to do a clean install, so I thought I would post up how I did it. I decided to keep this separate from the main Win 10 thread as it will get buried down a couple of pages in a matter of minutes and this seems to be something quite a few people are keen on.

For me, it has been a while since I last had an officially paid-for version of windows. But, there is no way in heck I am paying 150-200 quid for a full retail version of Windows 10. I was burned by Vista Ultimate and never compensated by Microsoft, not even with a free upgrade to 7. So I've been running an "extended trial" ever since.

Following Microsofts reasonable offer of free upgrade to 10 from 7/8/8.1... it is still very easy to get cheap and legitimate oem and retail keys for those operating systems. There is a reputable place selling retail keys for under 23 pounds and oem for under 14. For professional, I didn't check the prices for home.

Given the relatively low cost and the benefit of retail over oem, along with the upgrade honouring the difference between the two, I went ahead and purchased a Windows 8.1 Professional Retail license.

This first install is slightly longer than your original install as you have to either upgrade first or install from scratch first and then install 10 from scratch following this. But from this point on, you can continue to install Windows 10 from scratch without having to follow the upgrade process.

Procedure followed:

- If you have a fully licensed version of Windows 7 / 8 / 8.1 then you can start from here and follow the standard microsoft upgrade procedure to version 10.

- If you are currently running an illegitimate version of windows, then you will need to begin by installing a properly licensed version of Windows 7 / 8 / 8.1 to begin. I would highly recommend installing all drivers completely in order for the system id to be recognised properly for the upgrade.

- Complete the upgrade procedure to Windows 10, home or pro depending on your version.

- Once this has been completed, make sure that all drivers are installed and functioning properly.

- Activate windows & this will already be linked to the microsoft account you logged into or created during the windows 10 setup procedure.

- Use Magical Jellybean Keyfinder to find your new product key. There may be other software but this is the one I am familiar with. This makes it very easy to find your new Windows 10 product key, then write it down or copy and paste and email it to yourself or similar. This new key will be different from your 7/8/8.1 key. (please be warned, the latest release of this tool tries to install some crapware with it, so be sure to deselect the extra tool it tries to install... although if you miss this, it is not big deal as you are about to re-install the operating system from scratch anyway).

- Once you have this key secure, you can begin the normal install-from-scratch procedure via usb or dvd.

- When you reach the page asking you to enter your product key, enter the new key you have been given after your Windows 10 upgrade.

(this last step appears to be the place most people are getting stuck - the 7/8/8.1 key will not work and quite a few people are having problem with activating windows if they skip this entry and try to activate the trial version, even if it is linked to the same microsoft account they used in their upgrade)

- During the first setup, login with the same microsoft account you used during the upgrade

- Install all drivers

- Reboot PC

- Activate windows

(following this last reboot, windows had activated itself anyway).

- Enjoy clean install of Windows 10 :)



There may be extra steps included here that you don't require... it may be simpler... only quite a few people have been having problems and this procedure worked flawlessly for me the first time around.
 
But windows 10 upgrades dont use keys.. The microsoft website even says so.

The upgrades don't... that is correct.

The upgrade continues based on you 7/8/8.1 key.

A fresh/clean install (not an upgrade) requires a key for installation/activation.

The upgrade process "changes" your 7/8/8.1 key to a 10 key... it all happens in the background, but you are issued a new key & it helps with the installation if you extract this before the clean install (not the upgrade).

I have read of a few people who have been able to install it as a trial and then activate it... but quite a few are having problems doing it that way.

This way works... there is a teeny bit more effort involved, but the whole process is smoother, especially for those having trouble.
 
Excellent post, this is really good to know. Hopefully the extracted key will allow new installs of the retail version on new hardware without upgrading again.

Thank you and exactly... it did for me, hence the post.

I am running a clean retail fresh Windows 10 install now. Installed 10 directly onto a freshly formatted SSD, no 7/8/8.1 first :)
 
I did a fresh install of windows 10 on my tablet earlier ( after upgrading ) and never needed a key either... windows activated fine

I'm sure the Microsoft Account bit is optional. I have carried out upgrade and clean install with local account and it still works and activates fine.

I don't use a Microsoft account as don't have a need for 1 so use a local account for W10

when doing a clean install it asks twice for a key but you can skip this, I did on my clean install and then as soon as I was on the desktop it activated with no issues :)

Good news :)

As I mentioned... I have read of it working well for quite a few... but also people having trouble doing it by this method.

Hopefully my tips help those who are struggling with it :)
 
Possibly longer method but also a safe way is to clean install your previous version of windows 7/8/8.1 then upgrade to 10. Fresh install no probs.

That's not the point... that's still installing one OS on top of the other... that's an upgrade, it is not a clean install.

Or once upgraded, go to settings, update and recovery, reset and keep nothing.

Much easier than all that faff.

That's not a clean install... and you can set that before the upgrade too.

All that does is move all the bits to a different folder... go to you c: drive and you will see a folder windows.old

It also holds other bits clogging up the system like every other upgrade of any OS.

Clean install = speedier performance.

Thanks for taking the time to post this, very helpful!

:)
 
It doesn't format.

You need to install from a separate disk for a "clean" install.

Perhaps a little less relevant on an SSD with trim/garbage collection.

Does that option delete the windows.old folder or keep it and restore it as per upgrade?
 
Thx for guide, can i ask why the need to install and update all drivers if your going to format and reinstall anyway ? cheers

With the clean install pointer in the OP you refer to having all the drivers installed and working before you do the fresh install, is there a reason for this, I'm about to format the HDD and do a fresh install but I'm assuming MS will fond all my drivers automatically ..

Thanks

Yeh i would like to know this also, as whats the use of having all drivers installed, if your about to format drive and put clean install on, as all drivers will obviously be deleted.

The new activation is linked to your hardware... neither Win 8.1 or 10 found all the drivers for my hardware.

If windows doesn't recognise all the hardware, then it's possible when you do the next re-install with all hardware recognised, that it might reject it as a different PC.

That's why I did that... only took an extra 5-10 minutes or so for me as I already had all the drivers to hand...

Your mileage may vary... if you succeed without doing that, great... this guide was designed for people who are having trouble with the clean install process & this is a step I would be sure to include for anyone having problems.
 
I didn't even think to check stupidly! However tonight I have followed the guide in the OP. So in my case, with a clean install which did not want to activate, I did a clean install of 8.1 and confirmed it was activated. I upgraded to W10 via USB media and again confirmed it was activated. Took a copy of the key which I put in when doing a clean install of W10 and it activated straight away. Happy days!

Good news :)
