Even in case you’ve been utilizing PowerShell for some time, you would possibly need to double-check your desktop in opposition to my suggestions.

Home windows PowerShell ships with Home windows 10 and Home windows 11, however the bits haven’t modified within the picture for years. When you have put in PowerShell 7, that too might require some updating. Sadly, there are a couple of gotchas, however I may help you out.

Replace Assist Content material

The very first thing you must do on any new set up is replace the assistance. PowerShell ships with minimal assist. You solely want to do that on computer systems the place you’re operating PowerShell interactively and writing scripts. That is usually your Home windows 10/11 desktop. As a result of among the assist content material is in administrator-level directories, you must use an elevated PowerShell session run as an administrator.

The command is easy sufficient.

Replace-Assist -force

You must anticipate to see a couple of errors. Not each module has legitimate hyperlinks for updateable assist. If you happen to see errors for plenty of modules, one thing in all probability went incorrect. Be sure to run this in an elevated PowerShell session.

Assist content material is up to date on a regular basis, however there is no such thing as a mechanism to tell you when to replace assist. I manually replace assist at any time when I notice I haven’t executed it shortly. Or you possibly can put one thing in your PowerShell profile script.

$immediately = Get-Date
$days = 1,11,22
if ($days -contains $immediately.day) {
    #replace assist
    Write-Host "Updating assist through a background job" -ForegroundColor yellow
    [void](Begin-Job {Replace-Assist -force})
}

This may replace assistance on the desired day of the month.

PowerShell Get

A part of the replace course of goes to incorporate modules. This may use instructions from the PowerShellGet module, which itself ought to be up to date. Run Get-Module to check your model.

If you happen to don’t see any newer variations, it is advisable to replace this module.

update powershellget error

Properly, technically, it is advisable to set up it. As a result of v1.0.0.1 was not put in with Set up-Module, you may’t improve it. You need to set up it.

Set up-Module PowerShellGet -Drive

When you’ve executed this, you should utilize Replace-Module sooner or later. At this level, I like to recommend restarting your PowerShell session to make sure you load the brand new model of instructions like Discover-Module and Set up-Module.

The PowerShell Gallery was reconfigured some time in the past to require up to date TLS settings. If you happen to get errors looking for or set up modules that point out connection failures or “can’t discover module,” you would possibly want to regulate your safety settings. I imagine Microsoft has up to date Home windows 10/11 to keep away from this drawback, however in case you want it, run this command from a PowerShell immediate.

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

In case your OS isn’t present, you must put this assertion in your PowerShell profile script.

PSReadline

You completely need the most recent model of PSReadline. This module offers command completion and prediction, amongst different worthwhile companies.

default PSReadline

If that is the one model you see, it is advisable to improve. This module additionally ships with Home windows, so you may’t improve it. You need to set up it.

Set up-Module PSReadline -force

As with PowerShellGet, from right here on out, you may replace it.

Pester

If you’re writing scripts and modules, you also needs to be writing Pester checks. The Pester module ships with Home windows.

Not an issue. By now, you realize you must use Set up-Module.

Sorry. There’s a long-standing bug with the safety catalog related to the Pester module. I do not know why this hasn’t been resolved. Regardless, right here’s how one can set up it.

Set up-Module Pester -force -skipPublisherCheck

Abstract

Most of those duties are one-time occasions. When you get a couple of out-of-the-box modules put in, you may hold them updated with Replace-Module. I do know you’ll have a greater PowerShell expertise in case you take the time to run by these duties.
