If you Google How to get the best out of Windows 10 there are a lot of websites that offer great advice on Tips and Tweaks. The best choices are always near the top of the searches as those are the most viewed. They offer great advice and tutorials on how to make certain changes such as switching off services that you don't need. It's really hard to go into personal detail as everyone's computer needs are different. Basically what you were using before the upgrade should still work the same. If it doesn't then the software vendor needs to make an upgrade to the app to be compatible. If you find one that's not compatible just right click the app and go to Properties. From there you can change the compatibility mode to either Windows 7 or Windows 8.
