Win 10 is only version so far that deletes your previous licence if you upgraded to it. If you record your current win 8 licence key somewhere safe and then install win 7, you can always reinstall win 8 on PC again using the win 8 key. They don't over write anything.
If you ever put Win 10 on PC, you don't have to worry about its licence as the details for it are held on Microsoft servers. If you install win 10 on a PC, Win 10 will look on an activation server and see if the details of PC are recorded there. If you had win 10 on PC already, it will find it and activate PC for you.
Does it have win 7 drivers? Best look before jumping. Does it have multiple USB 2 slots? win 7 doesn't know what USB 3 is without drivers, so need to have USB 2 slots for kb/mouse and installer. What I would do is format the hdd before installing win 7 (mainly as its likely to be formatted as GPT and Win 7 needs MBR) and create a partition on drive that has all the drivers you need to install win 7 on PC. USB drivers really help make this easier, as do lan drivers.
Wait Windows 10 deletes my previous license? :O
I am in Windows 10 right now, but my laptop was preloaded with Windows 8..
I remember that i upgraded my Windows 8.1 to Windows 10 (just to try it out), and then a few days later went back to Windows 8.1 since i didn't like Windows 10 that much...
Then a few months later my PC somehow upgraded and installed Windows 10 again, after that i didn't care if i had Windows 10, because i didn't want to start to reinstall the drivers etc all over again...
Can't i return to Windows 8 by using the
"windows 8 media creation tool" like i did when i went back from Windows 10 to Windows 8? And from there record my license key and after that install Windows 7?
Hmm i believe it have Win 7 drivers, my laptop is ASUS X550C and according to this site: https://www.asus.com/Notebooks/X550CC/HelpDesk_Download/
It have Windows 7 drivers
