Hi Thomas,

Thanks for the input.

I just made sure to run two sets of two workstations. Two workstations with "Fall Creators Update" and two with the dreaded "Windows 10 April 2018 Update". Same machine. One is a VFP dev environment. One mimicks a corporate deployment workstation.

VFP dev environement works flawlessly. The issues are mostly on our sophisticated deployment. Yep a virtualized bundled exe with zero dependencies (all ocx and dll including com ones embedded). Works on all variations of XP, vista, W7, W8 and W10 upto this recent stuff!

At night I dream I could bundled my "legacy" (sic) VFP application into some certified MS application store stuff. Time to change dev environment:-)
