Can users of Mathematica on Windows 7 or Windows 8/8.1 upgrade their computers to Windows 10 – a process that began today? Does Mathematica work? Are all the settings, licenses, access to files and folders preserved? Is there anything one must be careful about?
I can confirm that upgrading to Windows 10 from either Windows 7 or Windows 8.1 (you can't upgrade from Windows 8 directly, you first have to upgrade to 8.1) leaves all your settings and licenses intact and that includes your Mathematica (9, 10.0, 10.1, 10.2) installation, I didn't have version 8 installed but I would guess it should work too. I have also noticed that Mathematica performs better on Windows 10 than in previous Windows versions. Windows 10 will preserve your files and folders, just select that option when upgrading. I've tried this on up to four PCs (including a laptop and an AIO), installation was smooth and every program works fine so far.
One thing to note is that with Windows 10, you should make sure your graphics drivers (I only have NVIDIA) are updated to the WHQL-certified versions, I know for sure this will affect Mathematica, if it's not updated. The drivers should/will be updated during your upgrade so this should not be a problem.
I upgraded three machines from Windows 7 to Windows 10, two of which were work machines containing installations of Mathematica 10.x (and earlier). So far I have encountered zero issues related to Mathematica with this Windows upgrade. From a personal perspective, upgrading to Windows 10 was very simple.
Also the QA team for Mathematica did a full test of Mathematica 10.2 on Windows 10 (and a prerelease version of it). There was one issue found related to STL and PLY import, but that was fixed before the 10.2 release.
Windows 10 was added to the list of supported platforms:
If you encounter any issues related specifically to Mathematica and Windows 10 (and not with the Windows 10 upgrade process itself), please do contact [email protected]. If you (accidentally or intentionally) do a clean installation of Windows 10, you will need to reinstall Mathematica and you will need to reactivate it.
