Windows 7 Install File

Posted on  by admin

Chances are you'll need to install Windows 7 from a USB device if you have a tablet, a small laptop, or a netbook device, few of which include optical drives as standard hardware.

As of January 2020, Microsoft no longer supports Windows 7. We recommend you upgrade from Windows 7 to Windows 10 to continue receiving security updates and technical support.

You must migrate the Windows 7 setup files onto a flash drive (or any USB-based storage) and then boot from that flash drive to get the Windows 7 installation process started. However, simply copying the files from your Windows 7 DVD to a flash drive won't work.

You have to specially prepare the USB device and then properly copy the Windows 7 install files to it before it'll work as you expect. You're in a similar, but slightly easier to solve, situation if you've purchased a Windows 7 ISO file directly from Microsoft and need that on a flash drive.
