Is there another OS besides Windows?

Linux and Mac OS.

Linux is an OS so it is therefore an answer.

And you should have said all of that in the first place if that's what you wanted.

Sorry I bothered.

Yes microsoft windows has built in back doors used by law enforcement and government agencies.
Freelance hackers for hire also exploit those same back doors which are easy enough to use.

But here is where that bad news gets worse because Mac OS and Linux also have back doors
put there so that law enforcement and government agencies can spy on you and disable your system.

Most likely you have been red flagged by the FBI and or Homeland Security and the NSA.
Which is why they are doing a take down on your computer system.
Switching to a different operating system won't help because they will do the same to Linux.
I should know because I have had extensive experience in this area.

The government will try to "Brick" your computer in the hopes that you will just throw it away
then the government goes rummaging through your trash to extract the hard drive out of the
computer so that they can more extensively go over the data and use it as hard evidence against you.

There are ways to defeat what Homeland Security and the NSA are doing to your computer
but you would have to gain a knowledge of how to repair and diagnose seemingly broken
motherboards and power supplies. To say that the malware is memory resident is the
only hint I am allowed to give you because telling you how to defeat government
actions against your computer system would be very frickin illegal.

Although it might be counter intuitive you might want to turn off secure boot
since the government will only weaponize it against you to lock you out of your own computer system.

Why is this so important if I may ask? Wait are you secretly Jason Bourne?   

Linux Mint is the distro that is closest to Windows 10, I think. Others are PopOS and Manjaro.

Then there's the boomer distro Chicago95 that looks like Windows 95.

You can still use Windows 7 or, better yet, Server 2008 R2 if you pay a fee for ESU. And there's 0patch: 0patch.com/



There is the Hackintosh. Although as Apple is ditching Intel and transitioning to their own CPU architecture (and kind of going back to the old days of PowerPC), its days are numbered.
