SCCM 2012 Hotfix - Per-computer variables for imported computers are not read in System Center 2012 R2 Configuration Manager

Symptoms:

Per-computer task sequence variables that are defined for imported computers are filtered out of client policies. This prevents the variables from being read during task sequence execution. This problem does not affect per-computer variables that are defined for existing clients.
