Hi Scythe,
I successfully removed all the HP rubbish on my computer. Thanks for your assistance.
For the TWEAKUI thing I am trying to work up the courage to use Revo Uninstaller, the MS clean-up application or RegCleaner.
Because I'm an old-school DOS man, I get very nervous when it comes to editing the registry
Extremely loathe to run an MS tool as well. Most of the things they serve up are rubbish!
I will come back to you when I finally work out what to do :O
Thanks!
