Will it allow native like bash script support on Windows? I use windows as my main OS and use cmder for CLI things but really miss proper bash script support.

Other than bash itself, does it mean it can be used to make whole set of GNU tools cross platform?

Absolutely. cosmos-3.0.1.zip contains bash, GNU coreutils, Emacs, and a whole lot more. All of which run great on the Windows console. On our github release page, there's also a cosmocc zip of a GNU/Linux style GCC compiler. Cosmo provides a refreshing way to build Windows software, because we use the System V ABI (i.e. long is actually 64-bit) when we build Windows software. So there's a much more consistent cross platform development experience.

Tried running bash by renaming it to bash.exe using both CMD and Powershell and both return "Access denied.

Even though Windows 10 already has Terminal and I was getting

     [error 2147942405 (0x80070005) when launching `C:\bin\bash -l']

I downloaded Terminal Preview which still throws the same error. Is Terminal or Terminal Preview the only way to run bash? There might be a way to configure cmder to use bash in a similar way you suggested for Terminal. Don't know how yet.

Try whitelisting the folder with Windows Defender. Sometimes when I get EACCES style errors on Windows mysteriously, it's because I need to recalibrate the security on the folder. Here's an example of something I ran once which fixed it.

    PS C:\WINDOWS\system32> $ACL = Get-ACL -Path C:\Users\jtunn
    PS C:\WINDOWS\system32> $ACL | Set-ACL -Path C:\bin

I also just uploaded cosmos-3.0.1.zip to Microsoft Security Intelligence to make sure they get whitelisted with their cloud security.

I linked bash to bash.exe and was able to start it however everything from /bin was failing with:

  The application was unable to start correctly (0xc0000142).

Turns out it doesn't work when I start bash by double click bash.exe but it works if I start it from cmd.exe.

Yes and yes.
