We have a large number of server 2019 core servers where the C:\Windows\Servicing\LCU folder is >6GB in size. I've done some research and found that this can be cleared with the Update Cleanup portion of the Disk Cleanup Manager, but of course that's not an option on server core. Has anyone found a good way to deal with sudden bloat in these folders?

Open a case to Microsoft for further professional help is a more effective way.

2021-03-03T15:58:54.093+00:00 Yeah, already tried that. You get the ability to cleanup the recycle bin, and that's it. Going to try with a /D today to see if I can save a registry configuration but not super hopeful.

Hi,
LCU stands for Last Cumulative Update. It seems it's just a backup folder in case you may want to uninstall latest CU.
Some users manually deleted the folders, looks like no noticeable side-effects so far.You could refer to the following link for reference:

2021-03-02T22:25:58.783+00:00 No, I Googled too, and found that. I've tried doing a gci -recurse | remove-item -recurse, but it only partially cleans it - it fails as "unable to find" a bunch of the files, and I'm still seeing 2GB left in it. And of course, most people suggest disk cleanup, but as I've said previously, that's not an option on Server Core. So thanks, but that's not a ton of help.
