Glad to see it's getting resolved Herb. If you'd like a utility tool that keeps your system clean, I recommend Advanced System Care (the newest version I think is 5.4). It's very simple to use and I've used this for quite a few years on my DAW as well as other computers at home(it's also Free). 

The only issue I've had with this is that the Registry Cleaner that comes with this is a bit "too efficient" as it cleaned out my registry for X1. I just disabled that option before letting ASC scan & clean out the rest of the PC and it has worked out very well.

Some of the things it does:

"Diagnose System includes optimizing and repairing the system configuration, preventing spyware, defragmenting the disk and a security analyzer, which scans the computer to find hijacked settings."

PORN.

Not that I think you have any Herb.

Just wanted to say that I've "heard" PORN can consume lots and lots and lots of disk (I hope I spelled that right) space.

Get one of these: 

I had to do a restore to get it stable. So far... the restore is working fine.   I've been back up and running on this for almost an hour now..... having to reinstall a few things but so far it looks good. 

probably got something corrupted somehow.... 

Thanks for the advice and Mesh... I'm trying that ASC to see how that helps.

whatever I did.... I now have 60gb of unused C drive space....and everything appears to be working correctly.....

Bapu... nope... not even a possibility .... nice to know you're thinking of me though....
