Keep Computer Active and MS Teams Green – Complete

Want to keep your Microsoft Teams status green even when you’re away from your computer?

I built a free, lightweight PowerShell tool that simulates real mouse activity — no clicking, no installs, and no admin rights needed. You just click two points on your screen… And enter how long you want it to run… And it moves your mouse between those points to keep your system awake — and your Teams status active. It even runs quietly in your system tray, and you can exit anytime. No shady apps. No background spyware. Just clean and simple PowerShell code you can inspect or customize.
Download the executable free — and if this helps you, give it a like and consider subscribing.
