Windows 10: Fighting security problems since going to Windows 10 Pro

Sometimes when I go to install a program, EVEN run a progroam, I get access denied errors or similar.
A program I've had installed for a few weeks, and have run many times gave me an access error on a file 3 layers deep in the Program Data folder.
I was the first user on the system, and I'm in the Admin group. That program I just mentioned gave me same error when I trieds Run as Administrator.
I've changed some security settings and added myself to key folders. I'm sure I shouldn't do that, but it's the only way I can run some things.
Windows 10 seems pretty stupid about security. If I'm in Admin group, and Administrator or Administrator group has all permissions, why shouldn't I?
It's making me grumpy. *Mad

I'm attaching an example of Process explorer (sure most of you are familiar with it) running from Admin login and running from my login. On my login, this has concerned me for some time, it shows Access Denied and/or Error opening on several processes.
If there is an error opening a process that Windows thinks is necessary, I feel it's likely to cause problems. And for an error to occur out of the blue on a program I installed weeks ago...

If there was a way to clean the slate on all security settings and start fresh, that's what I would try.
There is one thing I'll mention. I heard somewhere that you should NEVER enable the built in Admin Account. Well that's fine and dandy, but it's been the only way I could function on many occassions. But if there is something to that, it has not had an impact on my laptop. It's not given me any security problems, at least not since the upgrade to the current build.

Help, Gurus. I'm getting really frustrated with security issues.

How to eliminate duplicate files in DriverStore on Windows 10 wasting gigabytes of space?

Thank you for the advice. I looked at DriverStore Explorer ... too scary! (What is RAPR?!) Since the Anniversary update, and those that followed, I've got too many things that don't work, and my attempts to find all the right drivers has been mostly unsuccessful.
I just don't have the energy to fight with Windows anymore. No matter how much customers complain, it is obvious that Microsoft is not going to fix any of the existing problems. If I want my computer to work again, it will be with Ubuntu or Windows 7 Pro.

 

Sound Problems since going to Windows 10

I have allmost the same problem. There was no problem with recording in windows 7. But after upgrading to windows 10:

I have tried all the methods, but nothing helps. First I thought it was my external soundcard so I changed to Fireface UFX, but the same problem. Playback is ok and I can test it in the device. I can see that sound card is functioning. I can see the recording
source in the windows device, but I cannot test it.
