"i think my ashampoo winoptimizer suit does all the stuff u asked fer"

No way. If you try using JV PowerTools or a superior registry cleaner you will see that Ashampoo WinOptimizer Suite leaves stuff behind. Ashampoo is very 'safe', meaning by using the default settings you are only deleting what Ashamoo THINKS you should delete and forgets a ton of other rubbish.

"when unintsalling stuff...use ...Your Uninstaller....it deletes all da left overs that the windows uninstalller ignores"

This isn't true either. Again, using a superior registry cleaner will show you this.

'Your Uninstaller!' leaves stuff behind. If you want to get rid of things permanently and thoroughly try some of the registry cleaners I've already mentioned on page 1 of this thread. At least download JV16 PowerTools and try it, then do a deep scan in JV16's Registry Manager section and see what you think. Firstly run the Registry Cleaner though (while in JV16 go to 'Registry Tools', then choose the second icon), and see how many hundreds of useless things come up.

Trust me, I spent a long time working out which of these type of apps is best.
In fact all the ones I mentiones all catch things each other leaves behind, so you might think you have gotten rid of the junk but until you try about five different pieces of software you don't realize. None of them do the job absolutely 100%, so the answer is to run several.

Back to 'Your Uninstaller!' - as an example, say you installed GetRight, now uninstall it and choose to clean the left overs. After that if you were to check in the registry there would still be an entry for 'Headlight Software'. I haven't tried this but I'm using it as an example. You can almost guaranteed something is gonna be left behind.
