Enabling Windows Defender definitions in Windows 10 using a metered connection

When connected to a metered connection, Windows 10 won’t download updates.  This includes Windows Defender definitions.

Create a scheduled task to run the following command:

“c:\program files\windows defender\mpcmdrun.exe” –signatureupdate –mmpc

This is to run a signature update from the microsoft malware protection center (eg: Update from the internet).

The scheduled task can run as the user system, whether the user is logged in or not, and must be run with highest privileges.

If you want to test if your task is running correctly, you can run an elevated command prompt, issue the command mpcmdrun.exe -removedefinitions –all and then run the scheduled task.  This initial download may take some time as it will do a full download, not just a dynamic update.

mpcmdrun.exe /? gives the following command line options:

Powershell if file does not exist

Small gotcha that caught me recently, I needed to do a test-path but action if a file did NOT exist, and I had trouble getting it to work first go, so I’m writing this here:

## check file exists
if (!(Test-Path $FileToCheck))
     throw "$FileToCheck not found"

This will throw the exception if the file can not be found.

Batch converting video combining FFMpeg and Powershell

I had a bunch of MKV files that I needed to convert to mp4.  I don’t have any fancy video editing software, and found that a program called ffmpeg exists, which is a command line tool that will do this.  Once I verified that it would do what I wanted, I decided to write a powershell script that will do the work for me, which you can find here.

You will need to download and install ffmpeg and run the script.  I have defaulted ffmpeg to “c:\program files\ffmpeg\ffmpeg.exe” as this seems like the logical place for me.

If you have any comments, or ideas on how to improve, please let me know in the comments below.

Disable Office 2016 typing animation

To disable the office 2016 typing animation, navigate to:


Create a new Key called Graphics

In the Graphics key, create a new DWORD 32 bit value for DisableAnimations

Set a value of 1.  Log out and back in and the animations should no longer be active.
