powershell - New-SelfSignedCertificate will not run on Windows 7

Question

On a Windows 7 Professional system, it seems not possible to run New-SelfSignedCertificate. I could on a Windows 10 system.

Yes, the shell was started with "Run As Administrator."

PS C:> new-selfsignedcertificate
new-selfsignedcertificate : The term 'new-selfsignedcertificate' is not recognized as the name of a cmdlet,

Answer 1

As stated in the comments above, this isn't available in Windows 7.

However, if you're looking for something with a similar API and capability, then I have used & can recommend this from Microsoft Script Centre:
