About Windows 7 Pro OA

 Windows 7 was released to manufacturing on July 22, 2009, and became available for the public on October 22, 2009 (source).

Windows 7 is an operating system for your PC, made by Microsoft.

OA means OEM Activation – Original Equipment Manufacturer. It is already activated in BIOS when you buy a PC or laptop, so you don't need to enter the key and activate it yourself.

Pro here means the edition version. The most common editions are Home, Pro, or Ultimate edition.

Difference between Windows 7 Home, Pro, and Ultimate

  • Windows 7 Home Premium: aero enhancements, multitouch, home network groups, and media apps for playing movies and burning DVDs. Also, it supports only 16GB of physical memory.
  • Windows 7 Professional: everything in the Home edition plus enhanced networking features like domain joins, advanced backup, location-aware printing, and offline folders, as well as Mobility Center and Presentation Mode. Supports up to 192GB of physical memory.
  • Windows 7 Ultimate: everything Home and Pro have, plus all possible features Windows 7 may have. The full list is here.

From my experience, 99% of users don't need features in the Ultimate edition. It will just take disk space and resources.

How To Install Windows 7

You have your bootable USB with windows 7 installation files. Good job!

Now you need to set the bootable flash drive as a first boot priority in the bios settings. It could be done directly in BIOS, or you can call for a separate menu with just boot priority setting:

Keep the USB inserted and restart your computer. During loading, you should see “Press F11 change boot settings”. It could be F8 or any other key. So, press that button and make sure you set the bootable flash drive as a first boot priority.

Now restart your computer again, Windows 7 installation should begin, and you just follow installation steps, mostly clicking “Next”.
