Here are some suggestions that are rather broad and not specific. The specific recommendations get to be much too detailed and difficult to reproduce by others and I would surely make an error divide tried to tell you how to edit something directly in the registry.
Here are the general rules that I use for making changes to my systems. These are rather broad brute force methods that tend to be more reliable but appeared to be rather awkward and clumsy.
The first order is to make up frequent backups and checkpoints in the system. Just having the opportunity to go back a day can really make a big difference.
The second-order is to have more than one user account. There does not seem to be any penalty for having several user accounts on one installation of Windows. The user account seems to take up very little space on the hard drive. In most cases your application will put different settings into each user account as need be. So having several user accounts is one way to protect yourself while making experiments on application settings.
My third order of business is the use of additional partitions. This may seem to be an overkill, but it is often help me solve the problem. Windows will allow you to have installations of Windows 10 and Windows 7 and other combinations, even to installations of the same Windows 10 build. I have actually done that and it is one way to try out something different without destroying your main installation. So I have another installation of Windows 10 on the same hard drive and I can go there and try something out to see what it does.
Yes, those three ideas seem to be severe overkill. Granted, it does seem to be that way. But from my own experience years ago I have found that backup and backup and alternative methodology can make a big difference in your success rate. Don't be afraid to make your computer work hard. Your computer is well-suited to doing hard work.
Okay, that's the end of my lecture.
Last line of dictation.
