I have it disabled at startup. Really wasn't sure how to just turn it off. The slow boot issue with v2.0 seems to be resolved. When I enabled Disc Protection (and after it made the partition) it booted quite normally. I turned DP off and it took quite a while to boot, however, I believe it was just removing the partition as it stated it was going to do. If I want to try some software install that requires a boot I'll enable it. With Sandboxie I really don't see the need for it or Returnil Pro (which I installed the other day for free), although admittedly, I ran sandboxed inside Returnil and couldn't even tell, they were so compatible, just kind of overkill using both.
