How to reinstall Windows 10 if my computers used the free upgrade from 7 and 8?

Yes, still work, no need to call, just be sure to have internet access when you start to install 10, I work at pc shop and did this few days ago, used a key of 7 to put clean 10(wasn't used for upgrade).

 

How to reinstall Windows 10 if my computers used the free upgrade from 7 and 8?

Will windows 10 still accept the license keys from 7 and 8 now if I reinstall my computer?

Does Microsoft keep a list of users who upgraded to Win 10 using their 7 and 8 keys so that when users need to reinstall windows 10 the old keys would work?

Do I need to call in Microsoft to ask them to activate my Windows 10 when I give them my win 7 keys?

Both computers are laptops. The windows 7 machine had the serial printed on the back, and I needed to enter that when I upgraded to 10. The windows 8 machine had the serial built in inside its boot system so I didn't need to enter the key when I upgraded to 10, but I did manage to write down the keys using a fetcher program.

 

No More Clean-Installs for Vista Upgrades

When users were upgrading to Windows XP, the procedure was that users could simply insert their old Windows 98 or Windows 2000 CD at the appropriate time during a clean install without the need for the old OS to be installed at the time. However, Microsoft has decided to change this for Vista, and now requires a fully installed and activated version of your old OS already on the machine. This comes as an attempt to prevent illegal use of upgrade CDs, but could be inconvenient and time consuming when the time comes to reinstall. The new procedure for a reinstall is as follows:

• Install your old copy of Windows XP
• Activate it either online or over the phone
• Install Vista
