I purchased a Asus notebook, with built in Windows. Windows was expiring, and I did not have a disk, nor, would Windows allow me to use the key code.
After getting no help from the place of purchase, Microsoft, I was directed to Yogi, and their tech dept. was a enormous help. Yogi found problems, I didn't know I had. The price was reasonable, the help, invaluable.
Thank you Yogi!
