Hi! I'm your Slashdot assistant! I see you have misused the word "advise".
"Advise" is a verb. You advise someone on some subject matter.
"Advice" is a noun. You give someone advice.
Except that it does work for some purposes in some cases, as long as you're not expecting it to be a literal "truth serum".
Anything that suppresses higher brain function will make someone more likely to self-incriminate. Anybody who has been to a party with alcohol knows this. It might also cause someone to make stuff up or engage in embarrassing behavior, but that's not the same as "truth serum doesn't work at all."
Or you could look at a 1-2 year reinstall cycle as a positive: it's an opportunity to test and optimize your backup strategy, since desktop users rarely do that. You do keep backups, right?
20GB is not enough.
A fairly clean Windows 7 Pro VM I have (basic Word/Excel/Outlook/PP office, firefox, chrome, acrobat reader) takes up over 20G, mainly because of winsxs.
I don't do much with that VM. IOW, it's not pristine, but it's a lot cleaner than most win7 systems.
Windirstat reports 22.9GB in C:\windows with 13GB of that in C:\windows\winsxs
Some of that might be ntfs's equivalent of symlinks, but properties on C: reports 24.1GB used, 4.5GB free (I need to resize the VM disk eventually). I don't believe the C: space usage is a lie, even if C:\windows is slightly overreported by windirstat.
People do not live in a vacuum. People who believe in imaginary friends and believe those imaginary friends have sent facts and instructions for how to live, usually want to make everyone else believe those facts and live according to those instructions.
