Claude Desktop spins up a VM without no way of stopping it
TL;DR
Claude Desktop, a Windows application, unexpectedly launches a Hyper-V virtual machine consuming 1.8 GB of RAM on every start, even for chat-only use. This issue arises from the app triggering the Hyper-V Host Compute Service, which creates a virtual machine process.
✦ Why It Matters
Understanding this bug can help engineers optimize resource usage in applications that rely on virtualization.
Key Takeaways
- Report the bug to the developers for faster resolution.
- Monitor memory usage to identify performance issues.
- Consider disabling VirtualMachinePlatform if not using Cowork.
- Regularly clean up stale session files to optimize performance.
How It Works
The Claude Desktop app triggers the Hyper-V Host Compute Service via an RPC interface event, which spawns a vmwp.exe process hosting a full virtual machine. This process is initiated automatically at boot, leading to unnecessary resource consumption.
