After bloggers publish attack codes that exploit a failure in UAC (User Account Control), Microsoft announced that it will correct "failure" in future Windows 7 versions.

In the new version of the system, the UAC shows fewer user doubt windows than in Vista, since it uses a security certificate to ensure that the system's own programs are changing settings within Windows 7.

According to Rafael Rivera and Long Zheng, crackers can use codes ready to remotely bypass Windows 7 and disable UAC, leaving it free for any system change without the user noticing.

“No, Microsoft did not reverse UAC behavior on Windows 7 so it would work as in Vista", explained the spokesman.

Until this problem is fixed, some bloggers recommend that Windows 7 beta users set the "Always Notify" option as default.
