"I'll go and make a coffee whilst I wait for the file to open'' It took 2 years before W7 worked satisfactory. How many years till W10 works properly? Do I have to go thru this all over again. Howabout you develop a product that actually works properly before releasing it? Up to 30 seconds for a file to open for editing. That's extremely fustrating when I've got hundreds of files to edit. Audio preview box is empty, and none of your solutions have worked. Slow start-up. Failures to wake up from sleep. What's next? And I'm afraid to go back to W7, in case it messes up my computer even more.
