When the Operating System version requirements filter only contains the first two components of the Operating System version (Major.Minor), then ZENworks will only compare these two components.
In the example, when filtering ">5.0", the Operating System will have to be at least "5.1" (XP) in order for the requirement to evaluate as "true".
Windows 2003 is version "5.2" and therefore the filter will also evaluate as "true" when the filter specifies ">5.0".
When parts of the version information are omitted in the filter, then they will not be used for the evaluation, since the Operating System version consists of 4 separate numbers which are treated independently.
As a result, since the actual Operating System version of Windows 2000 SP4 is, for example:
Here the requirement ">5.0" will evaluate as false but ">5.0.0" will evaluate as true, since the actual Revision component is greater than "0" and the Build component is ignored.
