Background task for Hewlett-Packards DLA software ( D rive L etter A ssignment). HPs DLA gets installed when you installed the software that comes with their CD/DVD Writers. HPs DLA is packet writing software which enables you to store data onto CDs directly from within Windows applications, without using the actual CD Writing software (much like Roxios DirectCD.
Recommendation :
Many users have reported shutdown problems caused by TFSWCTRL "not responding". In all cases, since they were never using the DLA software and were instead using the CD Writing software to create their CDs, they simply de-installed HPs DLA and that solved all their problems with TFSWCTRL.
