Hello Kada,
Keep in mind that once the Software Update is installed, and the IsInstalled=TRUE is processed by the SMP to the database; the client is pulled from the Patch Intersect Filter for that update and is no longer targeted by the Software Update Policy. This is why the InstallLog.csv file was created.
When you check the InstallLog.csv file on the client; do you see that KB2862330 is installed with the v2 in the name?
It may be that the update was revised, the settings on the PMImport do not have the 'Enable distribution of newly added Software Updates' enabled, and therefore the Software Update Policy is not deploying the revised update v2.
Confirm the affected clients are targeted by the Software Update Policy for MS13-081 and that the Advanced Tab displays the Software Update Advertisement is enabled for KB2862330v2.
If the v2 update is present with the Exit Code 0 or 3010 (client rebooted); you may want to troubleshoot why the client's Patch Inventory is failing to be delivered / processed by the SMP as outlined on KM: HOWTO60750
If the update was trying to retarget then I would suspect a rules issue would be at play here, but where the Software Updates Tab is blank; it appears to be a problem with missing events data (Step 6 in the above mentioned KM article) or Patch Inventories failing to be processed.
Hope this helps,
Joshua
