Big thanks for help improving windows>=8 support (unfortunately still
overlooked).
I want do a fast test to see is your changes solve the bugs (and/or
occasional hangs) I have found trying spice-guest-tools 0.100 and
qxlwddm-0.12.zip on windows 10 guests. For tests your improvements I can
simply install spice-guest-tools.exe inside
flexvdi-guest-tools-2.2.3.exe and qxlwddm-0.13-flexvdi.zip?

Thanks for any reply and sorry for my bad english.
