Windows 10: Laptop with Windows 8 license and Win10 update: Reinstall Win10?

I have a slightly older laptop that came with Windows 8.1 and has the license key for it "built in". I updated it for free when Windows 10 came out. Now I would like to format it and reinstall it because I want to sell it. The question is, can I just put Windows 10 on it now, or do I have to use Windows 8 first and then update it again?

Win10: windows update stuck at never ending loop ?

When in win10:

• Update&security -> Windows update -> Finding update... .... .... ....

Planning to download the latest Win10.ISO (vers.1803) and manually update:
- Then wait that my ordered new SSD arrives and clone the old HDD to it.

 

Win10: windows update stuck at never ending loop ?

Hello
Win10: Windows update is stuck at never ending loop ? ( Last Win10 updates in 2017 ). Can't update the laptop. Genuine Win10 on a HP 2015 17.3" laptop that originally had Win8. ( CPU:AMD A9, GPU:Radeon R5 ).

If I download this below file does it manually install the latest updates of Win10 (=2018 April Update) without losing any files currently on the machine ? ( Mainly paid Office 2013 )
MediaCreationTool1803.exe
Download Windows 10

 

Windows 8 failure configuring updates and reverting

I agree 8 is awful! It's not for me though... I replaced a broken screen in a Win 8 laptop that was given to me and I am going to give it for free to someone that can't afford one so they can do homework at home. Yes I took it from 8 to 8.1 back on 10/09/2014. This is what I posted there...

"Great post! I found a similar one. I would like to point out that you may want to edit your OP...

1. Step 1 should read to disable AUTOMATIC updates, not disable manual updates.

2. KB2871398 should really read KB2871389

I would like to say that KB2917499 may also be needed as it was in my case. I also had to run the Windows Update Troubleshooter after installing those 2 updates. After these steps I was able to begin my 8.1 download from the Microsoft store. I don't know if it made a difference or not, but I also went into the Bios and disabled "Secure Boot."

It was a helpful post. Thanks!
