Windows 10: How can I re-install my free upgraded win 10?

Hi

About 2 years ago, I upgrade my genuine copy of Win 7 to Win 10 from Microsoft's site directly for free, but after some month I uninstall it because of some errors. Now I want to know how can I install Win 10 for free again on the same computer?
I have only my product key for win 7. Can you help me please?

:)

 

Upgrade from 8.1 to Win 10

Hi Roy,

Welcome to Microsoft Community.

• Is this laptop compatible with Windows 10?
• Are there drivers for Windows 10 for this laptop on HP website?

I would suggest you to temporarily disable/un-install any HP's software if you have installed.

Also, I would suggest you to start the upgrade by un-installing the updated drivers and installing basic windows drivers.

Follow the steps mentioned below:

• 
  Right on the start icon and click on device manager
  
• 
  Expand Network/Device adapters, Select the adapter, right click and click on un-install.
  
• 
  Restart the computer.
  
  Now start the upgrade from an ISO and see if that helps.
  
  Hope this helps.
  

 

Fresh Install of Win 10 without Serial Key?

Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

 

Win 10 clean install question

This is what I would do:

• Shrink the hard drive partition until it's small enough to fit on the SSD.
• Clone the Windows 8.1 setup to the SSD.
• Boot off the SSD and make sure that Windows 8.1 is happy (i.e., no complaints about activation).
• Upgrade to Windows 10 on the SSD.

This way, you know that Windows 8.1 has a valid setup on the SSD before doing anything else. Plus, the Windows 10 upgrade will be processed much faster on the SSD. Finally, you still have the hard drive setup to fall back to if anything goes wrong.
