I have SCCM2012 R2 CU3, I use to deploy windows 8.1 image on my Helix clients. For some reason SCCM2012 is not cleaning the _SMSTasksequence folder (it has other folders as Applybootsystem, contentcache, drivers, logs, osd, packages,sms and TSEnv) once the image deployment is complete, since the folder is big, the users come back to me after a week with a big red bar on C drive to free some space. What can be done to prevent this huge folder left behind after deployment. I just deployed a new image on X200 machine and on C drive _SMSTasksequence is cleaned by SCCM2012. I need help on why Helix clients get this folder left by sccm.
