# Installing Windows Server roles and features from PowerShell without stacking pending reboots

Get-WindowsFeature and Install-WindowsFeature -IncludeManagementTools cover discovery and install, -Source points at Features-on-Demand media when the local component store lacks the files, and the returned object tells the caller whether a restart is still owed.

## Goal
Install a server role or feature — including its management tools — from a remote PowerShell session, and know afterward whether a reboot is still pending.

## Prerequisites
Administrator rights on the target; the `ServerManager` module (built into Windows Server 2019/2022/2025); network or local access to feature source files if they were stripped from the image.

## Steps
1. Discover exact names first: `Get-WindowsFeature -ComputerName SRV1 | Where-Object InstallState -ne 'Installed'` — `Get-WindowsFeature` lists every role/feature with its `Name` and `InstallState`.
2. Install with management tools included: `Install-WindowsFeature -Name Web-Server, Web-Mgmt-Console -IncludeManagementTools -ComputerName SRV1`. `-IncludeManagementTools` installs the associated admin tools, not just the runtime.
3. If the feature files are missing from the local image — common on a minimal or Features-on-Demand-trimmed install — supply a source: `-Source \\server\share\sxs`. The documentation for `-Source` states it "specifies the path to feature files if the files are not available in the local feature store of the target computer or VHD."
4. Only pass `-Restart` when an unattended reboot is acceptable right now: `Install-WindowsFeature -Name ... -IncludeManagementTools -Restart`. Otherwise capture the result and act on it deliberately.
5. Inspect the result object rather than assuming success: `$r = Install-WindowsFeature -Name Web-Server; $r.Success; $r.ExitCode; $r.RestartNeeded`.

## Expected result
`$r.Success -eq $true`, `Get-WindowsFeature -Name Web-Server` reports `Installed`, and `$r.RestartNeeded` tells the caller whether to schedule `Restart-Computer -Force` before the feature is fully active.

## Limits and test basis
`Install-WindowsFeature` needs a working component store or an explicit `-Source`; without either, installation fails with a source-not-found error rather than silently succeeding. To undo, `Uninstall-WindowsFeature -Name Web-Server -IncludeManagementTools` removes the same set — run it with `-WhatIf` first to confirm scope, since it also removes dependent sub-features unless retained elsewhere. Because the cmdlets do not prompt by themselves, no `-Confirm:$false` is needed for non-interactive use; the only interactive risk is an unplanned reboot from `-Restart`, which is why step 4 makes it opt-in.
