Excuses, excuses, excuses... recently I was deleting files from my computer, progress bar jumped to 99 percent and estimated 5 minutes, it was longest 5 minute in my live I think it took about 3 hours to get from 99% to 100%. I do not think it is acceptable behavior. It should not take so long to delete files and it should not be so match inaccurate in estimations. Wondering how come Windows become number one OS in the world with this and many other issues.
