I recently noticed just how much left-over rubbish there is in my

I'm not aware of any problem with it; no slow-down detected.
I used regedit, exported it, checked file size and it's 273 MB.

How does this compare with other users? I'd like to know.

I ran a powershell script and it reported 153 MB. w7 ult x64, been
running alittle over a year, Office, Photoshop, Visual Studio, several
browsers. I've cleaned it with ccleaner maybe half a dozen times.
