to install powershell either download the zip/msi from github page or you can install thru
chocolatey. But I preferred going with msi file for now.
The claim is that you can run powershell core side-by-side, which is not a requirement for me- but wanted to move over to it for some time now.
Anyway, I installed this in
C:\PowerShell\6.0.1 directory & added it to
Path environment variable on the machine- so is accessible to all uesrs.
