Tom! This is something I'm very passionate about, that's relevant to this. I feel very strongly that no progress bar should ever display that something is 100% complete. I feel like that's redundant. If it's 100% complete, the window should close, or move on to the next state. It's the operating system version of a thank you email. For some reason whenever I make this argument, people don't seem to agree. For some reason, I think your brain works enough like mine that you will.,(reply>), @eDoc2020 from a front end perspective, even if it's 99.9%, we should use integer floors and show 99%, because it IS NOT 100% done. Again, when the process is complete, telling me it's 100% done is redundant in terms of a progress bar.,(reply>), I have mixed feelings about it, and it really comes down to rounding. Do you round to the nearest percent or do you always round down? Either way Windows Update is bad where it spends a fairly large amount of time at 100%.
