WOW! there's some great stuff in your blog.
I now have indexing turned off, don't notice any improvement though.
Am now cosidering a format and clean install, some of my problems are not mentioned by anyone else so may be peculiar to my setup.
One more thing if I may :This will ENABLE the 20% bandwidth that the system reserves for itself.
Click Start and type and enter "gpedit.msc"
This opens the group policy editor.
Or in my case says "no items match your search"
All the other tips I tried worked why not this one?
Thanks for being so generous with you knowledge.
