VMware PowerCLI Installation Guide 2026 | Online, Offline & First vCenter Connection

In this episode of the PowerCLI Mastery Series, we get our hands dirty
with a complete PowerCLI installation walkthrough on Windows — covering
both the online method using PowerShell Gallery and the offline method
for air-gapped or restricted environments where your target machine has
no internet access.

We also tackle one of the most common issues new PowerCLI users face —
invalid certificate warnings when connecting to vCenter — and finish the
episode by making our very first successful connection to a vCenter 8
server.

By the end of this episode, your machine will be fully set up and ready
to follow along with every script in this series.

always use properly signed SSL certificates on your vCenter server.

⚠️ Never hardcode credentials (username/password) in scripts you
plan to share or store in version control. We will cover secure
credential handling in a later episode.
