předpokládal jsem u xp stejnou činnost, nic tomu nebrání
pokud se bavis o tomto - http://en.wikipedia.org/wiki/Mandatory_Integrity_C ontrol
tak plati toto tvzeni z wiki:
In the context of the Microsoft Windows range of operating systems, Mandatory Integrity Control (MIC) or Integrity levels (or Protected Mode in the context of Internet Explorer)[1] is a core security feature, introduced in Windows Vista and Windows Server 2008, that adds Integrity Levels (IL) to processes running in a login session. (See also Security features new to Windows Vista.) This mechanism is able to selectively restrict the access permissions of certain programs or software components in contexts that are considered to be potentially less trustworthy, compared with other contexts running under the same user account that are more trusted. Windows Vista defines four integrity levels: Low (SID: S-1-16-4096), Medium (SID: S-1-16-8192), High (SID: S-1-16-12288), and System (SID: S-1-16-16384).
...
One of the most common applications for integrity controls in Windows is with Internet Explorer 7 and Internet Explorer 8, which can run in "Protected Mode" on Windows Vista and later operating systems. In this configuration, the iexplore.exe process runs with a Low integrity level to limit its access to the underlying system, and thereby prevent some classes of security vulnerabilities; since Internet Explorer in this case runs as a Low-IL process, it cannot modify system level objects—file and registry operations are instead virtualized.

Problem je, ze to bezi na Win XP, takze je to nepouzitelne.
