Hello
I have had the same issues after Fall Creators Update and I have tried all the tricks and updates which have been instructed up until so far in this thread.
My PC: HP EliteBook 8770 w
Windows 10 Pro 64-bit
Intel Core i7-3840QM CPU @ 2.80GHz
RAM: 8 GB
SSD: Kingston SUV400S372240G
Today I found a new trick. I launched HP Performance Tuneup from the HP Support Assistant. This seems to help a lot. Please note that HP Performance Tuneup is only a few days old new wizard in HP Support Assistant.
My Nitro 11.0.6.326 is now running almost as fast as before Fall Creators Update. Tab switching, stamps and printing are working swiftly.
