Laptop with 7 home 64 installed want to upgrade to 10.
Read in Tomshardware that I could down load install 10 and when key is asked for just enter the Win7 key and MS would accept it.
Is that true?
Also read here on Cnet that if it has been tagged for upgrade entering old 7 key will work.
This laptop was going to be updated with the free but glitched and wouldn't upgrade. Now the link in update area says too late can't do it.
Also in Tomshardware was advised to buy cheap key. Will that be trustworthy?
