The solution written in the HowToGeek web site: "http://www.howtogeek.com/122145/what-happened-to-solitaire-and-minesweeper-in-windows-8/" does work on a 64 bit machine, however you must copy and paste to the Program Files(x86) folder not the Program Files folder since the games were written for a 32 bit machine. I did what the article directs..."
To do so manually, you can use a hex editor to open each game’s .exe file and search for the following bytes:
7D 04 83 65 FC 00 33 C0 83 7D FC 01 0F 94 C0
Replace the first 7D in the sequence above with EB, and then save the file. You’ll need to do this manually for each game’s .exe file
and it works just as described.
