Hi,

I am using Lenovo IdealCentre Q190 with preloaded Windows 8.1 in it. Now i planning to upgrade to Windows 10. Can i do fresh install windows 10 using its OEM windows 8.1 key?

I tried with the W7 key and worked.

Are u using retail or preloaded oem key?

OEM key on the laptop.

So this method still work ya in 2021? because i read microsoft forum, some say used to work last time but not now anymore.

Direct upgrade from the existing Windows 8.1.

when did you try this bro?

Its not available anymore. As free upgrade only till 2016

afaik fresh install cannot.. upgrade can

How to upgrade? I thought the upgrade service already ended

Try it. It is still possible. I just did it for a Win7 PC.

Download iso windows10 install , alot legit windows10 key on web if u know how to find

U can choose to download the upgrade assistant and upgrade via online, or download the ISO file

Cannot, i am using for business.

December 2020.

Coming from legit Win7 Pro MSDNAA key from my uni days
This MSDNAA key didnt work to install Win10 Pro.

I used a generic Win10Pro key on the internet. It did a trial version (to select Win10 pro).
Generic keys (aka: "default keys") for Windows 10 from Microsoft will allow you to install a specific Windows 10 edition you want, but will not activate it.

Then once windows can boot as normal I used back my legit Win7 Pro MSDNAA key and it worked to activate,

Haven try it out yet. As per my system doesnt show windows 10 upgrade option for my windows upgrade.

Create installation media using the official tool also cannot?
I see win8 is listed there.

Will need a separate thumbdrive.
see Using the tool to create installation media (USB flash drive, DVD, or ISO file) to install Windows 10 on a different PC (click to show more or less information)

Officially the "free upgrade in-situ" option may not be available since offer expired but doing it the long way still legit and works.

Cannot, but after do installation media, and do reinstall windows 10 using usb, do i still need entrry my key?

Meaning if windows 7 home >>>> windows 10 home, u using ur oem key back ya?
must have same version only can use right?>

There are ways to extract the OEM Windows 8.1 key. Get it and write it down.

Another suggestion is to swap out the old HDD/SSD with a new one and do a clean install so that if anything goes wrong you can just revert to the previous OS by swapping in the old HDD.

If you don't have another HDD/SSD to swap, do a system image backup of the installation to an external storage that you can restore from in case you screw up.

Anything that can go wrong, usually does go wrong since we don't know what specific issues or restrictions your mini desktop has.

I have 2 laptops. Both bought used and came with W7Pro and W8. I formatted both with the W10Pro installation USB stick. After done, both showed up Activation required. I merely keyed in the keys from underneath the laptop and bang, both activated. Need internet access for this to work.

1. Before do anything, please follow AbbyCom steps and email the product key for win8 to yourself for safekeeping.
Backup all files first in case you need to wipe clean the drive.

2. Using the USB media tool from microsoft make the boot thumbdrive.
3. Install win10 from USB thumbdrive using generic key. - https://winaero.com/generic-key-to-install-windows-10-rtm/
4. This generic key is just to select u wan win10 pro or home or moon
5. Finish installation process. Once win10 can boot and work normally (can load desktop) use your win8 key in step 1 that you saved, to ACTIVATE win10.

Those r legit leak company license with hundred and thousand times use count .

P.S, if my windows is Windows 8.1 Single Language with Bing, What version of windows 10 i will get?

on microsoft site

Windows 10 (Home) Single Language.

7 was nice.

10 even better.

I am using Home by the way.

I just dusted off an old PC with, ahem, "original" Win7Pro today, and it upgraded to Win10Pro after going to Microsoft's upgrade webpage, all without any issue.

Win10Pro is now activated "with a digital license". Looks like MS still is allowing free upgrades, even though there are no more free upgrades officially.
