hi, this here is a support forum for the firefox browser and other mozilla products. i'm sorry that we cannot provide help for windows specific issues after an update to a new windows version. in this case it's better to consult microsoft's support at http://windows.microsoft.com/en-us/windows-10/ support instead. thank you for your understanding!

Hi

I do not think that this is a Firefox query, but I will try my best to help.

I have done the update myself from Windows 7 to Windows 10. The games that were previously installed are removed and replaced with other options.

I have not played them myself, but if you go to the Start button, All apps and scroll down the list, you should see Candy Crush Saga and Microsoft Solitaire Collection. I think that you can download others from the Store (the Windows carry bag icon).

I hope this helps.
