Open UltraISO in Win7 cannot modify virtual drive configuration Resolution

This question once puzzled me for a long time, but also did not find the solution in the on-line search, the Netizen provides the solution all is installs other virtual optical drive software, like daemon and so on. Undeniable daemon in the virtual optical drive field than UltraISO to be more powerful, a lot of virtual optical drive to enter the game must be used daemon to run, but the advantages of UltraISO is also very obvious, simple and easy to burn, you can write to the image to the U disk, Made into a system installation or PE disk, so UltraISO for me is also a necessary software.

Back to the question mentioned in the title:

A sudden flash of light today, probably Win7. UAC (user Account Control) caused UltraISO insufficient permissions to set the number of virtual CD drives. My UAC is set to the default state, and the use of the default settings for UAC in this state creates a great illusion:

For example, some icons in the lower right corner of the "shield" installation files, double hit meeting pop-up UAC control window, prompted whether to continue. This creates the feeling that the file requires a higher privilege to trigger UAC. The UAC dialog box pops up when some software runs, not just the installation files.

The problem is that the UltraISO runtime does not eject the UAC dialog box, which gives me the illusion that UltraISO is working. Not really, UltraISO did not get the right, so, "Run as Administrator," The problem is solved!

Summarize:

Windows7 is not recommended to turn UAC off, except for computer security experts. For software that is safe and reliable, the installation or runtime can and is necessary to run with administrator privileges. For software that cannot be determined, we can install or open directly, if the software contains trojans or viruses, open without administrator rights, most of the computer can not cause harm.
