Slooow login with CTM

I did a clean Win7 x64 install this past weekend. Spent many hours installing updated drivers and software.
I decided to give CTM a test run.
It (this version release) installed correctly [I say].
After two days, it did it’s thing at (cold) bootup, and I seemed pleased it was functioning as expected.
Soon after, (the past two days), logins have become very slow, both relog-in and boot login.
I uninstalled CTM (it did this correctly, albeit slowly). I was able to start windows and log in (obviously, as I am here).
My login time has reduced back to normal.

On a second note, CTM has taken 50GB of space from a drive I told it not to protect. 500G drive, formatted NTFS has 465G space. 250G used by myself, leaves 200G available. Currently states I only have 144G space available, data volume has not grown, still at 250G.
Upon uninstall, it did not return my drive space to me.
(How do I retrieve my drive space back without losing my data?)
