I recently switched over to MS for AV protection. I just noticed that there are several exclusions, most are in Windows/system32 folder. Does MS automatically add those files to the list of exclusions? Should I remove them from the list?

Thanks for your help!

Normally, there are no such automatical exclusions.
There are a few types of Defender's exclusions that can be managed from Windows Security Center >> Virus & threat protection :
  1. Allowed threats
    Allowed threats that have been previously quarantined
  2. Manage settings >> Exclusions
    4 types are available: File, Folder, File type, Process
What are your exclusions and which executables are excluded?

You have used illegal software activation tools that added these entries to Defender exclusions. Please note, that MalwareTips does not support people who use such tools.

Edit.
Sometimes people are forced to use such tools, but generally it is unethical and risky. The attackers can exploit the vulnerabilities in activation drivers to take control over the computer (even if the activation tool was not malicious).

Not possible. I only just started using Defender in the last week and it was disabled before. I have installed no software of any kind.

So another person did it. The illegal activator installed on your computer is for Microsoft products. You can have pirated Windows OS or MS Office.

I agree with @Andy Ful on this one. You have an activator on your system. It is typical for those to add exclusions to Defender as well as sometimes also being used to serve malware (because why not). If your OS was preinstalled when you bought the computer, it is possible that the person who sold it to you, installed the activator so they can get a better price.

Imho, you should get a proper Windows license and re-install the OS. The person who did this may have installed other stuff as well. Your system is not safe in its current state.
