Windows 10 Hdmi-Vga adapter not working

Just upgraded to windows 10.  Having a HP-laptop a 20 inch was being used during my journey with windows 7.  Now it will not work at all.  Have uninstalled / installed, checked for updates  several times but nothing works.  Anyone have any ideas?

Your title is saying HDMI-VGA adapter not working, so what is it that the laptop is not working with the HDMI adapter or the system is not working need a little more clear info, as being a HP laptop you can do a hard reset by holding the power button down until it shuts down then remove the battery and AC power adapter, now hold the power button down for 10-15 secs release,  now plug the AC adapter with out the battery power up the system and see if it is working okay it may take a few min's to complete loading, if ok install the battery.

After working with AMD tech support regarding proper driver for Radeon HD 5000 and correct configuration, made driver and hardware changes recommended.  None of this helped.  Their last comment was it was a hardware problem with my computer and would require me carrying it to a repair shop.

Decided I had read enough posts regarding similar problems and that I did not have a hardware problem I reverted back to Windows 7.  In less that 15 minutes my system was working perfectly.  No more problems with flickering monitor.
