CCleaner

That's strange. I've never had that problem and I've been using it for years. I've used others in the past that messed up my AutoCAD products but CCleaner has never done that. Plus, it will make a backup of the registry entries it deletes if you tell it to, then you can just put them back if it screws up something.

Ditto. CCLeaner rocks.

If you allow your users to log in as local administrators you have a far bigger security risk. If you don't they can't update java anyway, so the reminders are a nuisance and a constant source of support calls.
Better to turn off auto-update and manage updates though group policy, scripts, third party applications or whatever works best for you.

I am glad you have placed Revo Uninstaller in the list! It is a program I use almost every single time I work on client's PCs. The normal Windows "remove programs" feature is almost useless. Not completely, but almost. R.U. is tremendous at digging out crap that doesn't need to be on a system. That, coupled with a lot of command line removals, helps me to get my clients happy with their systems once again.

My choice of tools is Sysinternals Autoruns to stop crapware from running on boot up and CCleaner to safety clear out temp files such as the ones AutoCAD products leave behind.

So you managed to Google "crapware" and "removal", took a few screen shots and called it a publication. No testing involved, no good or bad, no advice.
Looks pretty crap to me.
