Currently, some of my accessories programs are gone, including Calculator. However, if I try to use Add/Remove Windows Components, it adds the accessories, but removes access to Internet Explorer and Windows Media Player. If I reallow access to IE and Media Player, it uninstalls some of the Accessories. Even if Accessories or IE and Media Player aren't checked, they will still be uninstalled or reinstalled. What could be the problem?
