Acrordr update hogging memory

I am having a terrible time with memory on my computer. It keeps announcing it's short on memory. I have an older HP Stream tablet running Windows 10, not able to be undated to Windows 11, and no way to increase the storage on the device. I move gigs of data to flash drives and delete programs I wasn't using, manage to get a few gigs clear, and then the problem re-emerges after a few weeks. I went through the storage, tallying up the sizes of all the visible folders in C plus the other areas where it will give me sizes, and found almost 10 gigs unaccounted for. I used something called TreeSize which identified the major problem as Acrobat, specifically AcroRdrDCx64...and-so-on, 15 files and an archive totalling 8 gigs. AcroRdrDCx...etc shows up on a file search in the ProgramData/Acrobat/Arm folder; I presume that's a hidden folder since it doesn't show up in my Windows file folder index. My question is this: is my computer failing to delete old updates after they're installed? If so, how do I fix this to both get rid of the existing excess and stop it from happening again? If not, how do I keep these updates from grabbing up all the available memory? I only have Adobe Reader, and I don't think that one is supposed to be taking 20% of my hard drive, so clearly my computer is doing something wrong.
