Upgrading To Windows 10 , Easy Method?

Hello,

Basically i have a whole fleet of computers that need to be upgraded at my office

There is like a total of about 45 that have windows 7 and 8

Is there an easier method to upgrading them than this video below?


Downloaded and installing from the micro tool takes time... the whole process takes 2.5 hrs per computer provided no errors happen..

Some people state you can put your windows 7 and 8 keys on the windows 10 installation but this has never worked for me.

The Microsoft tool ( media creation?) upgrade directly from Microsoft website does work as it already tried it on a couple of computers.

I would like to cut down the time to just using a windows 10 cd or usb drive
Is there a faster, legit easier way to upgrade ( that does not require me to pay for windows 10)?

 

You want to legally upgrade 45 company computers to Windows 10 for free?
No.

 

Why not install Windows from network boot using the Windows Installer?
This will save you time across multiple devices, but as Eldon says, you will need to pay.

 

How can i retrieve windows 8 and 10 keys on desktops without having to install an operating system or running a software on a pre existing OS.

I am fully aware i can run something like magicjellybean keyfinder but this is obviously a software that requires an OS, i want to extract the keys directly from the bios without installing any OS ( perhaps running them from a usb stick etc.)
