	tl;dr: Claude Desktop on Windows spawns a ~1.8 GB Hyper-V VM (Vmmem) on every launch once Cowork/agent mode has been used, even for chat-only sessions, consuming over 11% of RAM on a 16 GB system. The bug reporter also found 2,689 stale Cowork session files that never get cleaned up, and the only workaround is disabling VirtualMachinePlatform or killing vmwp/vmcompute after each launch. The request: only spin up VM infrastructure on demand when Cowork is actually invoked.
	HN Discussion: ↑Anthropic lacks engineering craft and ships poor quality desktop software ↑Cowork VM should be opt-in rather than forced on all users ↑Users are losing control over their own machines to opaque system processes •Workarounds exist like disabling Virtual Machine Platform to skip VM creation ~Broader race between AI companies and OS vendors explains rushed, sloppy integrations
