Hi Thanh Nguyen,

Stop letting background bloatware kill your new Lunar Lake's battery. WorkloadsSessionHost is not a core Windows system process. It is almost always tied to the pre-installed Dev Home app (or sometimes the Windows App for Cloud PCs). It has a known memory leak issue and will destroy your battery life by running useless background virtualization or sync tasks.

Since you are running a fresh install and only need Chrome and Teams, you absolutely do not need it. Here is the exact way to fix this and get your battery life back:

1. Identify and Nuke the App:

• Right-click one of those WorkloadsSessionHost processes in Task Manager and select Open file location.

It will likely point to a folder for Microsoft.Windows.DevHome or similar.

Open PowerShell as Administrator and run this command to remove it entirely: Get-AppxPackage *DevHome* | Remove-AppxPackage (If the file location pointed to a different app, you can simply uninstall that specific app from Settings > Apps).

2. Stop Background Startups:

Go to Settings > Apps > Startup.

Turn off EVERYTHING except Windows Security and your essential hardware drivers. You don't need apps pre-loading in the background if you want maximum battery efficiency.

Reboot your machine after removing it. Your Ultra 7 258v is designed to easily give you 10+ hours of battery life, not 1 hour. If this helps you reclaim your battery, please click "Accept Answer".

Hi Thanh Nguyen,

Just doing a quick follow-up to see if you managed to get your battery life back. Did nuking the Dev Home app and disabling the background startups stop WorkloadsSessionHost from eating your RAM?

If your Lunar Lake chip is still draining too fast or if you need any more help optimizing it, just drop a comment. Always happy to help!
