Upgrading Client VDA

To upgrade VDAs installed on machines running Windows 8.x or Window 7 to Windows 10, Citrix recommends reimaging Windows 7 and Windows 8.x machines to Windows 10 and then installing the supported VDA for Windows 10. If reimaging is not an option, uninstall the VDA before upgrading the operating system; otherwise, the VDA will be in an unsupported state.
