Your chatbot got a secret roommate
Claude Desktop spins up a VM without no way of stopping it
Claude users say the app secretly fires up a giant memory-hogging machine and won’t let go
TLDR: A Windows user says Claude Desktop starts a hidden mini-computer in the background every time it opens, burning memory even for basic chat. Commenters are roasting it as bloated and sneaky, though a few argue it may be a speed boost done in the worst possible way.
Claude Desktop on Windows is getting dragged online after one user found that simply opening the app can quietly launch a hidden virtual machine that eats around 1.8 GB of memory—even if you just want a normal chat. On a mid-range laptop, that’s a big chunk of performance gone before you’ve typed a single word, and the community reaction is somewhere between furious, exhausted, and deeply amused. One commenter joked, “It’s becoming self-aware! Quick, lock down the nuclear codes!” which pretty much captures the mood: half bug report, half sci-fi panic meme.
The loudest complaints aren’t just about the memory hit. Users are also mad that Claude’s Cowork feature appears to behave like an uninvited houseguest, with one person saying it also drops a roughly 10 GB bundle on systems and offers no easy way to remove it. Another claimed the app gobbled up 12 GB on their machine, turning grumbling into full-on outrage. That sparked the big debate in the comments: is this a sloppy, user-hostile mess, or a clumsy attempt at making the app faster? One more technical reply argued this kind of background setup can be a legit speed trick—if it starts only when needed and shuts down after. That “if” is doing a lot of work.
The result is classic tech drama: some users are posting workarounds, some are threatening to quit, and others are just roasting the app for acting like it rented a whole apartment inside their laptop. Even the pile of 2,689 stale session files found by the original reporter has become part of the spectacle—less bug, more digital hoarder horror story.
Key Points
- •The bug report says Claude Desktop on Windows starts a Hyper-V VM consuming about 1.8 GB of RAM on every launch, even for chat-only use.
- •The issue was reproduced on Windows 11 Pro with VirtualMachinePlatform enabled after Cowork or agent mode had been used at least once.
- •The report says Claude Desktop triggers `vmcompute`, which launches `vmwp.exe`, and the VM appears as `Vmmem` in Task Manager.
- •Diagnostics in the article say WSL, Docker, Hyper-V management tools, and Windows Sandbox were not installed or enabled, leaving VirtualMachinePlatform as the only active virtualization feature.
- •Deleting 2,689 stale session files and killing VM-related processes did not prevent the VM from respawning; disabling VirtualMachinePlatform was reported as the only reliable workaround.
