Worried about available space for big updates

[Phazoner]

I recently uninstalled some stuff from my C drive (little SSD) and I got 30GBs free, so it had 40GB total free space. During a week more or less I noticed the space was shrinking to 10GB total free space, but then it made the Fall Creators Update and I got back my 30GBs so it just was a W10 update.

I'm needing that 40GB for new stuff and I'm worried about future updates. What if a new update doesn't fit in the main drive? Will it just be downloaded in one of the HDDs? Can I set it to download updates in the HDD by default?

Thanks

If you're filling your boot drive and not keeping your heavy and apps and programs on an a secondary disk, then the answer is to upgrade the SSD.

There will be no miracles when it comes to storage.

My main SSD is 128GB sized, only installed W10, Libreoffice, Gimp, Unity, Steam and stuff like that. Downloaded data, games, etc are aimed to the HDD but it seems weird to me that I just have to buy another SSD because Windows just wants to download update data in the boot disk and apparently doesn't let us to download it in the data drives...

A 120GB drive is TooSmall. We see that here every day. You have to be rabid about what you put on that drive.
And no, you can't make Updates go to your HDD.

Move some stuff off the 120GB, or get a larger drive.
