After I upgraded to win10 from win8.1, I downloaded the update for Intel using ASUS software, and the brightness control came back.
After that, I downloaded another update I think is something called NVIDIA VGA if I'm not mistaken, windows stucked at loading screen ever since, my guess is the new driver is not compatible with win10, or because I did not do a clean up before updating the drivers.

Now trying to fresh install win10, may I ask if I do fresh installation after cleaning up the OS partition, do I still need to do this driver clean up before I update my drivers?

I think right now the download speed is quite slow from Microsoft, it's only around half the speed I'm getting compared to when I downloaded during midnight 2 days ago.
I got careless though, just created a bootable USB drive without making a backup of the ISO file, and my Win10 failed to load up after I updated my graphic card driver. I then realized I created the bootable drive for BIOS format instead of UEFI which my laptop is using.
Now I have to re-download the ISO file again.

I found a useful guide, which said you can use non-Windows OS, or use your mobile phone to access the link below:
https://www.microsoft.com/en-us/software-download/windows10

And instead of redirecting you to the link to download media creation tool, you can actually select Windows 10 version and 32, 64bit version ISO file to download directly from Microsoft server. In that case, you can use download manager to download, instead of through the Media Creation Tool.

Saw this in the Microsoft website link:
Windows 10 editions below are valid for both Windows 10 Home and Windows 10 Pro.

So you can just choose the 1st option.

Just fresh installed my ASUS N550JK laptop with Windows 10, the windows update installed most of the drivers required automatically.
When I went looking at ASUS support page, I saw some drivers available for download for Windows 10.

I see stuffs like BSMI certification, CB certification, BIOS EC firmware, and also BIOS Flash Utility. To be honest those things sounds alien to me, I'm wondering if installing those drivers are necessary?

It is still possible to get a download link from Microsoft server using the method mentioned in my post above.

And I realize using this way to download, the download speed is faster than using the media creation tool.

From what I understand is the free upgrade offer only lasts for 1 year, starting from the date Windows 10 is released to the public, which is 29/7/2015. Therefore you can only get the free upgrade offer until 29/7/2016.

And after you upgraded your computer to Windows 10, it will be valid for lifetime, as long as your computer still working. Pretty much like how previous windows versions work, you get it activated, and it lasts until your computer 'kong'.

Correct me if I'm wrong.

If I'm not mistaken, since previous versions like Windows 7 and 8, the license key is stored in motherboard.
I did a fresh install, by reformatting my partition used for OS, and the windows 10 activated itself after installation.

You will need to contact Microsoft to get it activated if the hardware changes is deemed to be over the limit they set.
I think replacing storage drive only is fine, unless you're talking about replacing motherboard, graphic card all in 1 shot.

Correct me if I'm wrong.

I got the driver update automatically through the Windows Update.
I think they're slowly releasing the updates now, today I just got another driver update which installed the PCI Controller driver.

Happened to me as well. I updated the NVIDIA VGA driver through ASUS software that came pre-installed when it was running Win8.1. Screen went blackout after installed the driver. Reboot, forever stuck at 'white circle of death', it just won't boot to Windows successfully. Attempt to repair failed as well.

I had to reformat my OS drive and fresh install Win10 to get everything running again.

AFAIK it will come automatically, there's pretty much nothing you can do.

But you can always upgrade 'manually' using ISO file downloaded from Microsoft.
I recommend you check around the Internet though, to see if your laptop model is ready for upgrade to Win10, since usually people face a lot of driver compatibility issue after upgrading.

I manually searched for the touchpad driver for my laptop model on the manufacturer website, and it solved the problem.

Thought of sharing this here, and see what you guys think about this.
I upgraded my laptop to Windows 10 and fresh installed it in early August.
Things were going well, until last Tuesday, when my laptop screen decided to give up.

I last used it in the morning, and it was functioning well. I put the laptop in 'sleep' mode. And when I switched it on in the afternoon, the screen just won't show anything at all. I tried reinstalling display drivers also won't help. Had to plug it to an external monitor using the HDMI output to backup my laptop.

Sent it to authorized service centre, and got it fixed. I went to collect it today, found out they replaced the motherboard , and reformatted my laptop, it's running a fresh install of Windows 8.1, just like when I just bought it.

When I was signing the service form the receptionist gave me, I saw a remark on the form writing: "Win10 not stable, ask customer better dun upgrade". The receptionist didn't mention anything regarding this, but I saw it while I was signing on the form nonetheless.

So, now I'm wondering, is it really possible that Win10 screwed up my laptop's motherboard?

Using ASUS N550JK, the model isn't mentioned in the links you shared, but 1 thing in common is that my laptop also using NVIDIA GPU.

Yeah, I'm aware that my laptop is supported according to ASUS, I actually downloaded some drivers from their support website. That's why I'm wondering if I should trust the tech staff or not.
Maybe I should just stick to Windows 8.1 for now as it's quite stable, upgrade to Windows 10 only when the end of 1 year free activation period is near.

Well yeah, I upgraded to Windows 10 just because I wanted to try out new stuffs. I feel that my laptop runs a bit smoother on Windows 10 than on Windows 8.1. But it's okay, I can live with it. I'm currently studying overseas, so my laptop is the only computer I have with me right now, can't afford any risk of breaking it.

I thought Windows 10 is Microsoft's last release of OS?
