There are real sizes being listed on removal, expand the Components on the Apply page as they are being removed, or see in the log.
There are few issues with predicting or showing sizes:
- sometimes a connected component might remove bits of another, if they are both getting removed, so to get precisely the size of a single component, best is to run only its removal.
- Windows Updates bits are tied to each component and depending what cumulative update does that month, or you have integrated more than one, the size will increase.
- different Windows versions, I am only tracking the latest when adding new sizes, not gonna spend time on all of them as it's just informative to know which ones are the biggest.
- Predicting size before removals would take processing time and no real benefit as far as I can see.
Thanks.
