Hi CheckMK Community,

as part of our Community work, we are publishing our PowerShell written Windows Update Check now as Open Source Plugin for everyone.
It is completely new written and you can set all kind of warn and crit levels for your Windows Updates.
We have this Check Running since 2023 on all kind of Windows Systems, now feel free to use it too.
We tried to remove our OEM Branding for the end Users as good as possible.

Have fun!

The file header currently states:

# Unauthorized copying of this file, via any medium is strictly prohibited
# Proprietary and confidential

do you want to change that to make this a proper release :slight_smile: ?

Buenas,
¿Cómo puedo descargar el archivo powershell? Imagino que sin ese powershell, aunque instale y habite el mkp, no funcionará.
Gracias.
