  • If it is an OEM system builder installation then download Belarc Adviser and it will tell you what your key is. However, if this is an OEM SLP activation then the key you need to use to perform a clean installation is on a COA sticker on the bottom, back or side of your computer or possibly in the battery compartment of some laptops.
