I just found this tip online for removing the "junk" from your hard drive after Vista Service Pack 1 was installed. I ran it on my Vista Home Basic laptop, it took 1-2 min and saved another ~0.8gb (after I have run ccleaner many times).
The tip was found at http://www.labnol.org/software/tutorials/f...unk-files/2641/ and required the running of the file vsp1cln.exe (i.e. Vista SP1 Clean dot exe)
N.B. I don't have Vista SP2 installed on my laptop. When I tried this on my desktop which is running Vista Home Premium with SP2 the file was not present. and I was unable to clean these files.
I just wondered whether Piriform could add this to a future version of CCleaner?
Now, let me have a look to see if there is a similar clean up for SP2.
