Most issues pertaining to Windows 8, 8.1 etc end up being user fault or system specific. While I am not arguing that there may be a delay in opening charms etc (as I wouldn't know, I disabled it all) it would help people in here if you would complete your system specs via your profile in User CP. P.S. Notice the lack of profanities in my post.
