It's not in the known faults list, but the Microsoft update KB4013429 completely destroys Adobe Photoshop CS4 both 32-bit and 64-bit versions, reducing them to a crawl where mouse clicks take upwards of 30 seconds to respond where they would normally do so in less than a second.
1. How do you report these issues to Microsoft? It's extremely hard to find any way to give feedback or contact them
2. How do I block the update so it doesn't come back after uninstalling? I have tried the Microsoft 'Hide Updates troubleshooter package' https://support.microsoft.com/en-us/help/3073930/how-to-temporarily-prevent-a-driver-update-from-reinstalling-in-windows-10 which is designed for that purpose but it isn't stopping the ones I hide from reinstalling.
