If you're ever forced to use Windows, just install nushell. The speedup is wild, and along with it comes many nice quality of life features.

Nushell is good on the Unixes as well, but the defaults there are less annoying. I regularly revert to bash because there's just some thing I've memorized in bash, and bash doesn't make me want to scream.

Note that this is just my perspective on it as an interactive shell. I've never used it for scripting.

Windows already has a very good shell called PowerShell.

There is one company who decides what PowerShell is, and they are not known for stability in many areas.

Just as easily as Aero switched to Metro, syntax in PowerShell will do what they want, despite impacts to your legacy scripting.

The POSIX shell, on the other hand, is a POSIX standard controlled by the Austin group. The classic adaptation is the Debian Dash shell, which is both tiny and fast, and changes are very, very slow.

Dash can be linked with libedit and used as an interactive shell. Everyone should do so, before learning non-standard extensions in Korn, Bash, Zsh, et al.

Shells are a matter of taste to a great extent. These are different envelopes of features, stability, and portability.
