It sure is good that there are forums where one can go and get answers buddy, but Bill Gaites shouldn't make 'em in the first place.
shouldn't make what? security features that people have been asking for since windows 98?
This is what pisses me off. The main "problem" with windows for years has been security, and people are always complaining that it's so easy for it to get infected. The reason for this was because by default everybody is an administrator, and also that the limited user account functionality of pre-vista operating systems was lacking (most programs refused to install or work). So Microsoft, for some silly reason, decided to enhance the security of the system the
exact same way that linux does, which is to make administrative tasks require elevation. This is UAC. It's no different with Linux (well, on the surface) which requires you to use sudo or for the desktop environment to display the graphical sudo prompt as necessary.
Security is not free. It's not something that MS can add transparently and nobody will notice it except for fewer "infections".
chkdsk requires admin permission to open the disk and analyze it. In this instance, it doesn't make sense to some people. But consider if it was another tool that was opening the disk to implant a Boot sector virus. They both open the disk for exclusive sector-based access. They both require elevation.
In either case, I usually open cmd.exe with admin rights easily, start, type cmd.exe in the search bar, then press the application key (which shows the right click shortcut) and select run as admin. easy as pie. It doesn't work on the command prompt item though, since that doesn't have a run as admin item for whatever reason.
