Norton Anti Virus - but no viruses were found,..it couldn't find them if they jumped up and bit it in the neck ..
taskmanager is actually one of the first things to disable ..look for diskeeper lite ( freeware for doze it uses backoffice manager but way faster as the onboard 'doze "defrag" lies to you about what it did )..ie : most times it didn't defrag at all ..just moved the head on your HD some to fool you ..and showed you some cute GUI stuff
then look for "clean up" ..temp file , GID remover etc ..all the stuff that 'doze opens and forgets to bin when it shuts ..
then look for a real back up prog there are many ..use incremental "if diff" back ups to usb key ( not to another part of the HD or even a different HD ..too long to explain here ..just that's wrong!)..
then kill windoze automated **** ups ..( updates ) ...dou you really want to be a beta tester for redmonds latest patch :)..
oh ..and watch your spooler ..they can get antsy and lock up all kinds of stuff ..
clear your clip board each time you exit an app ..
so what do you need taskmanager for ..?
