Update PHP CLI version (2 replies)

I have updated my wamp server to the latest 3.3.5 64b version and have installed and switched to the latest PHP 8.3.9 version.
Now I want also remove the php8.1.28 used for CLI.
I have added the php 8.3.9 to the windows path, so WAMP should use the php 8.3.9 CLI.

My questions:
- How do I check which PHP CLI version is used?
- How do I remove the old php 8.1.28? Do I simple delete the php 8.1.28 folder?

Thanks,
Filip
