I messed up and let the hard drive of our Teams Rooms PC get completely full. It was down to just half a gig left earlier, but now it's 100% full, and I'm unable to connect remotely or access any command prompts. I used TreeSize to check what was taking up space, and it seems like most of it is consumed by WinSxS and the Teams Rooms software. I tried running the command dism /online /cleanup-image /analyzecomponentstore, but it didn't identify any files for deletion, and the cleanup command gave me an error. I've deleted as much as I could, turned off hyperfil.sys, and tried using Cleanmgr, but nothing seems to work. With an important meeting tomorrow, I'm worried the Teams Rooms software won't function due to the lack of space. Has anyone experienced a similar issue or have any suggestions?

In a situation like this, the simplest fix is to clone the disk to a larger drive and swap it out. It's pretty standard sysadmin work, and it can save you a lot of hassle with a full disk.
Make sure to disable system restore and delete all restore points. Also, using built-in disk cleanup and running BleachBit with appropriate options could help clear out some space.
Try accessing the admin share remotely and deleting any temp files that might be taking up space. That could free up just enough room to get you back in business.
Wow, how small is this hard drive? It’s concerning that WinSxS is taking up so much space. Have you checked if major Windows upgrades might have reset your WinSxS size? It could be a factor.
Is this only a Teams Rooms computer? If so, consider just reimaging the PC. You can monitor the drive’s usage afterward to figure out what caused it to fill up.
Yeah, I’ve noticed major updates for Windows 10 seem to affect WinSxS, but I’m not sure about Windows 11. It could be part of your issue too.
My go-to in these cases is to pull the drive and connect it to a dock, then use tools like TreeSize or WinDirStat to see what’s really filling it up. If it’s simply a lack of space, cloning it to a larger drive is a good route to go as well.
But honestly, if you’re pulling the drive, why would you choose TreeSize over something like WizTree? 😂
Yeah, using a dock makes sense, but why not just analyze from a remote connection?

I just figured I’d start with TreeSize since it’s familiar, but I'll look into WizTree for faster results!
