In the previous parts, we created a code signing certificate and used it to add a digital signature to a PowerShell script file. Yet what good can a digital signature do that was added to a PowerShell script file?
Use Get-AuthenticodeSignature to reveal the secrets found in the digital signature. Just…
In our previous tip we explained how you can use New-SelfSignedCert to create a self-signed code signing certificate. Today, we’ll use a self-signed or corporate code signing certificate to actually start and digitally sign a Powershell script.
For this, take any PowerShell script file you want…
Adding a digital signature to a PowerShell script is no black magic anymore these days, and while you ideally need an official “trusted” code signing certificate from your corporate IT or trusted authority, even this is not mandatory anymore these days.

This tool can remove a variety of data garbage and at times removes many gigabytes of space. What makes it interesting for PowerShell is its support for automation.
To automate hard drive cleanup, first you need to launch…
If you’d like to programmatically unpair a paired Bluetooth device, then there is no built-in cmdlet available. Still PowerShell can do the trick, and it often can even unpair Bluetooth devices that won’t remove via the UI or keeps coming back.
What you need first to remove a Bluetooth device…

PS> explorer.exe ms-settings-connectabledevices:devicediscovery
It immediately pops up a dialog showing all Bluetooth devices. Just add a function to PowerShell so you don’t have…
Identifying Bluetooth devices that your computer has connected to is as easy as a one-liner:
PS> Get-PnpDevice -Class Bluetooth
Status Class FriendlyName InstanceId
