Following the second link provided by @mkennedy's comment I found an FAQ: Is Windows 10 certified with Esri's ArcGIS products? which says:
For those running ArcGIS 10.3.1 and upgrading to Windows 10, when launching ArcGIS for Desktop, ArcGIS Administrator, or ArcGIS License Manager, the following error message may be received:

That FAQ includes a procedure for repairing the license.
