Hi hany,

You can refer to this case and find the answer by BurrWalnut, it seems that he tested Office 2007 with Windows 10 Technical Preview in his environment and it works fine.

And the MVP S.Sengupta also said Office 2007 is compatible with Windows 10.

If you need more information about Windows 10. I suggest you could consult your issue in Windows 10 forum.
