Stellar service!
I accidentally bought the wrong windows key and was so worried this meant I would have to reinstall all my data after doing an upgrade.
I emailed Justin to see if he could help me. He replied within a few minutes, giving a me a video tutorial to look at. I watched that and it wasn't workable for me so I emailed him back telling him that. Within 5 minutes I had anther video tutorial to watch and this one worked - no issues. My computer updated, no data lost, and all working fine.
I can't recommend Tight Tech and Justin highly enough - stellar service and yes you can buy their OEM keys with full faith that they work, and their service is second to none if you have any issues.
Extremely highly recommended.
