PowerShell modules: installation and command reference

Read Windows event and diagnostic data with Get-WinEvent and related cmdlets while filtering at the provider instead of after retrieval.

Use core management cmdlets for services, processes, files and computers, and verify object types before filtering or formatting output.

Discover and install modules with Find-PSResource and Install-PSResource, checking repository trust, version constraints and command-name changes.

Inspect execution policy, signatures and secure strings with security cmdlets while treating execution policy as a safety feature, not a boundary.

Record console sessions with transcripts and interact with the host using Read-Host, Start-Transcript, and Stop-Transcript.

Transform, measure, sort and export objects with Utility cmdlets while keeping formatting commands at the end of the pipeline.

Connect with Connect-AzAccount, inspect subscriptions with Get-AzSubscription and set the intended tenant and subscription context before Azure changes.

Inspect Azure VMs with Get-AzVM, read power state explicitly and manage disks or scale sets without confusing configuration with live status.

Find vaults with Get-AzKeyVault, retrieve secrets deliberately and distinguish control-plane access from permission to read secret values.

Inspect Azure virtual networks, subnets, NSGs and public IPs with Az.Network while keeping resource group, region and object IDs explicit.

Inventory Azure resources with Get-AzResource and Get-AzResourceGroup, then scope changes carefully by subscription, resource group, type and tag.

Work with Azure storage accounts and data services, keeping management-plane resources separate from blob, file, queue and table operations.

Connect with Connect-ExchangeOnline and query mailboxes with Get-EXOMailbox while requesting only the properties your report actually needs.

Connect to Microsoft Graph with explicit scopes, inspect the active context and query only the users, groups or devices your automation needs.

Connect to the SharePoint Online admin service, inventory sites with Get-SPOSite and verify tenant permissions before changing site settings.

Connect to Microsoft Teams, inspect teams and policies, and account for role permissions and eventual consistency before judging a change unsuccessful.

Query users, groups and computers with Get-ADUser and Get-ADGroup, then avoid broad searches by choosing a search base and requested properties.

Inspect DHCP scopes, leases, reservations and options with Get-DhcpServerv4Scope before changing address pools or client configuration.

Query DNS zones and records with Get-DnsServerZone and Get-DnsServerResourceRecord before changing forwarders, aging or scavenging.

Find Group Policy objects with Get-GPO and export evidence with Get-GPOReport before changing links, inheritance or enforcement.

Inspect VMs with Get-VM, review checkpoints and virtual switches, and distinguish configured state from replication and runtime health.

Inspect Windows Firewall profiles and rules with Get-NetFirewallProfile and Get-NetFirewallRule before changing direction, scope or enforcement.

Diagnose addresses, routes and TCP connections with Get-NetIPAddress, Get-NetRoute and Get-NetTCPConnection using the correct interface context.

Inspect physical disks, partitions, volumes and Storage Spaces with Get-Disk and Get-Volume before any destructive initialization or formatting step.

Write repeatable PowerShell tests with Describe, It and Should, then isolate dependencies with mocks that target the command actually called.

Configure command history, prediction, completion and key handlers with PSReadLine while checking host support and avoiding shared-history surprises.

Run Invoke-ScriptAnalyzer with explicit rules and settings, separate style findings from correctness issues and suppress rules only with a reason.

Inspect task definitions, triggers and principals with Get-ScheduledTask, then verify execution history instead of assuming registration means success.
