wrong windows version. check your windows version (it's either pro, home, home single language, x86 or x64) and download the correct iso.

if you have upgraded before (run setup.exe in windows), just skip places asking you for key.

what do you mean ? I haven't upgrade my pc before...I straight using windows 8.1 after buying it ..

Run setup.exe found on the ISO from inside Windows 8.1 first to upgrade, this will activate Windows 10 and tie it to your machine.

Reset/repair/clean install ONLY AFTER upgrading ....

Nope my windows7 laptop I over a year not touch it when I open for first time I directly boot to botable usb with windows 10 inside that I download from other laptop.. I finished install and successfully but when I try activate I get the error...

How to run windows 8.1 iso? I btw, I dont hv the windows 8.1 installation filed too....

mount the downloaded iso to ur hdd and run the setup.exe file

You mean win10 installation files??

yeah the windows 10 installation files u downloaded in iso form, u extract it to ur desktop or whatever. Then run the setup and upgrade

How to activate it? Or it will activate itself automatically??

it will activate automatically they said, after u finish installing windows 10. Im still upgrading mine lol

Use the W10 Media Creation Tool, download the ISO, either create a USB flash drive or mount it to your desktop, run setup.exe from inside Windows 7 or 8.1, let it upgrade and activate (best to be connected to the Internet via network cable), then only can you reset/repair/clean install W10 (not necessary, but this is what I did and the system is running flawlessly).

On a system with a SSD drive, the entire upgrade and clean re-install should take about 20-30 mins using the ISO method.

Any problems, feel free to PM me ...

the upgrade path has been highlighted many times in this thread. i have no clue why people are still getting it all wrong lol

1. you need to upgrade the activated os first. connect the computer with activated os to the internet, download the iso with the correct windows version for the activated os with media creation tool. extract the iso contents in a folder or just create a bootable usb out of the iso. run the setup.exe in the folder or bootable usb in normal windows environment (not booting it from usb) to do upgrade (the computer must be connected to the internet during the upgrade);
2. once you have completed the upgrade, connect to internet again to make sure the new w10 is activated. that's all for the upgrade.
3. if you wanna do clean install, do step 1 and 2 above first, then boot the computer with the bootable usb instead of windows. you can wipe the os drive clean, and then proceed. when asked for key, skip it and proceed. after clean install, connect the computer with new w10 to the internet and it will be activated automatically. no key is required.

note that for the free upgrade offer, you only need to run step 1 and 2 once (the upgrade), then you can do clean installs as many times as you like, without w10 key, for the lifetime of the device.

i think your windows version is single language x64 bit.

wrong. read my reply above.

You mean Win 10 don't need key license ? just activate it only will do ?

Yes. This is made possible because the W10 activation is tied to your existing hardware configuration (which is kept by Microsoft), so you can clean install on the same device (with minor upgrades) as many times as you like.

Is the upgrade process long if I do it from a bootabe usb ? how long will it take ?

all I see people here got lot problem install because cant wait for windows 10 to give notice it time to able to upgrade. all want rushing for it

not long, i install to SSD take less than 1hour including 3/4times restart

It works! Thanks a lot!

Now Asus GPU Tweak can't be use... lol

Changing language to English (US) works!

Its the installation process IMO. A lot of stupid error's. By far the most complicated windows to install/upgrade. If only they could send it the way they did using windows 8.1 through the app store would be so much better.
