Types of Windows 7 Consumer Keys

There are 4 types of retail consumer keys for Windows 7:

  1. Retail key: This key comes with a retail box or download copy of Windows 7, and can be used for a clean install or upgrade.
  2. Retail Upgrade key: This key comes with a reduced-price upgrade only version of Windows 7 & can be used for upgrade only.
  3. OEM COA Non-SLP key:  This is the regular OEM key without the special BIOS check. This type of key is provided with copies of Windows marked for purchase with a new PC only.
  4. OEM SLP key: This key is used for OEM computers that use BIOS-locked activation, used by large PC  manufacturers.

These keys are generally supported for use with retail or OEM installation media.
