Laptop new win 10 play?

Have a laptop that is about 6 years old and Win 8 was installed. When Win 10 came I installed the laptop from the Internet Win 10 Home. And at Win 8, it also started that the laptop did not load so fast, it was already slower. If I play Win 10 times completely new so it runs faster? Format the hard drive and win 10 on it. It is a normal hard drive with 2 partitions. Only Win 10 Home away and Win 10 Pro on it? Is that possible? Or only Win 10 Home? I hope someone can help, that would be great. I'm already saying thank you

As long as you do not need special network sharing, home is enough and if you have a home on it your key is also valid. To be sure, just connect to a mircosoft account.

Take windows mediacreation tool, finish CD DVD or USB stick and reinstall Windows 10. Then install your drivers for the laptop, found on the manufacturer's site.

And yes, if you just did the upgrade then it's usually not that smooth.

For Win 10 Home you have a license, for Win 10 Pro you have to buy a new one.

So you can only reinstall Win 10 Home, you do not even need to enter a license key.
