A couple of things to do. First you need to download LatencyMon to check you setup work and to see if you have actually improved anything as you make adjustments. Next download CClean (free version is fine) and use it, particularly the Registry cleaner part of it. Then go to the Sweetwater website and follow their set up guide for your DAW. Pay attention to their advice on the USB hubs.
Finally, here is what I have done to make Win10 a better OS for my DAW. Uninstall Windows Explorer, leave only the EDGE browser. And NOTE: removing the Explorer browser from your Programs list doesn’t mean that the Explorer browser might still be listed somewhere else in the OS. Google ‘removing Explorer’, and if you see that CClean keeps showing it in it’s browser cleanup area that you need to do more work. Now take a look at Windows Security - I think this is the biggest culprit for issues. Click on this icon in the lower left hand of your taskbar and pull up the whole Windows Security panel. You have said that you are not online? Actually, I think this approach causes more issues with Win10 than you might think. IMO, it’s better to have you PC capable of going on line and then using the ‘Airplane Mode’ in the Notifications Pop UP Window when you use your PC for recording. I think I am seeing that Microsoft has put in some serious security fail safes that are not possible to avoid permanently. In other words - the OS is constantly searching for security issues whether you are on line or not.
Back to the Windows Security panel. Do you see these 7 icons: ‘Virus and threat’, ‘Account protection’, ‘Firewall and network’, ‘App and browser control’, ‘Device security’, ‘Device performance & health’, and ‘Family option’? On the first 5 icons, you need to see a GREEN CHECKMARK on each one. If you don’t, then like I suggested, the OS will keep searching for a cause and suggesting a solution. This is the process that wrecks your DAW experience and bogs down the OS. OK, so click on each of these icons. As each window opens, you will see a list of items click on each item and then decide what you want Windows to do in each case. You need to look at every single line.
Alright, I’ll circle back. Good luck, I find that Win10 is a good DAW OS with a little work.
