With PowerShell you can kill a process with the Stop-Process cmdlet. While the Get-Process cmdlet let’s you get a listing of processes from a remote machine, sadly Stop-Process doesn’t allow you to connect to a remote machine. Most possibilities in PowerShell are just .NET and WMI monikers. So as soon as PowerShell doesn’t allow me […]

Here’s a PowerShell script that allows you to monitor processes on the local or a remote PC. It’s based on the Get-Process cmdlet. It loops every secon, compares changes in the process list and displays them nicely on the screen. It shows a green line when a new process runs and a yellow line when […]

Recently, I was wondering how much code I would need to do basic hardware and software inventory on several remote systems. After experimenting a little bit I came up with the following line of code: Get-Content pcs.txt | foreach { Write-Host $_ -f Green; $pc=$_; Get-Content wmi.txt | foreach { Get-WmiObject $_ -ComputerName $pc } […]

When you’re using the PowerShell module for Hyper-V from James O’Neill (a.k.a. jamesone) then you’ll find out that many cmdlets don’t accept string collections as variable. Here’s an example: Import-Module c:\psmodules\HyperV\HyperV.psd1 $Hosts = “HV01,HV02,HV03,HV04” Stop-VM -VM VM03 -Server $HostsString -Force Throws this error: Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) At c:\psmodules\HyperV\VM.ps1:73 […]

With PowerShell we can run a BPA-scan, store it as a baseline and compare it with our current situation. Here is a PowerShell script to establish the […]

For example: Microsoft SCCM allows you to boot a remote computer (wake it up from power off) to install Windows Updates. If you don’t have SCCM, there are hundreds of alternative software […]

PowerShell provides some commands to manipulate services, but that doesn’t work on remote computers! The script you can find below demonstrates that stopping a service on a remote computer using Stop-Service is not working. First I verify that the MSDTC service is running on the local machine and a remote machine: server2. If I want […]

It’s possible to compress a folder or file since Windows NT. It’s a feature of the NTFS-filesystem. Normally we would do that on the properties of the folder or file in the Windows Explorer, but you can do this with PowerShell too! Just use this command: Invoke-WmiMethod -Path “Win32_Directory.Name=’C:\Test'” -Name compress And to Uncompress the […]

The other day I stumbled upon a nice PowerShell command to use the speech API found on modern Windows Operating Systems. With this script PowerShell can talk to you! Great for situations where you want to hear about the progress of your script. Or maybe to tell you there’s an alert instead of showing the […]

Not too long ago I migrated my e-mail, calendar and contacts to the cloud. The migration was very smooth except for one thing. For some unknown reason a reminder was added to all my all-day appointments. I use these appointments for birthdays and that sort of events. I never use a reminder on my all-day […]

One of my clients asked me how to check for expired certificates. This simple script opens the certificate store through the PS-drive CERT: and lists all certificates that are soon to expire. You can change the threshold to any value in the first line. Here’s the script: $threshold = 30 #Number of days to look […]
