SOLVED Temp Files A La Grande

[Bif]

So after upgrade to threshold 2 I've noticed that in my storage the Temp File is huge at 16.5 GB and the "Other" (whatever that is) is also large.I'm a regular user of Ccleaner but would like to get some advice on whether I should run it to clean some of these files up? or just leave things alone as they might be (Windows.Old 10) files and deleting would be detrimental if I wanted to revert back to previous build.AND what the heck is this "Other" file that is taking up so much real estate?

deleting would be detrimental if I wanted to revert back to previous build

I don't know if I have anything positive to contribute to your query, but.....
Before I deleted anything that I had questions about, I would create a disk image and then I would mount it and inspect its' contents to assure that I had a strong and viable fallback position.
OF course I would have already done that also, prior to any upgrade / update and would never find myself relying on any native feature to return my machine to a previous state.
I enjoy being able to relatively fearlessly do whatever I want to my machine, knowing that I have a disk image to fall back on, just in case.
AND I don't mean the native Windows System Image utility. I mean.......

Great advice as usual,will look into this as suggested.What I find strange is that I searched for the %temp% folder and there are only a few items in there with a size of a mere 7.35mb...
so I'm thinking these are hidden system files or the like and I may just leave them be, as I have plenty of space left on the hard drive.
I thought computers were suppose to make life easier!!
