Hi all!
I am having problems while copying data from one drive to another, to and from external usb drive (or even 2 gb flash drive) and even over the network (wifi or lan both) .. the windows gets very very slow .. 100% cpu usage .. the process svchost uses it all .. if i try to open windows explorer .. it takes atleast a minute to open .. unable to watch any video file as the video gets frozen only the audio comes .. what should i do??

You stated that you did an upgrade from Vista, correct? (not a custom install)

@Mitchell: i correct myself .. i had done a clean install .. formatted the C drive .. installed windows .. installed all the required drivers from the hp upgrade cd that came with the windows7 dvd .. and also updated them from the hp site itself ..
i have just noticed that the problem mainly occurs when someone is copying files from my sharing (this problem never occured in vista) .. cpu usage immediately shoots up to 99-100% ..

after some snooping around and trying to fix the problem .. i found the problem related to registry problems and hdd fragmentations .. both my laptop hdds are 95% full .. after defragging them .. and cleaning/repairing the registry the performance is much much better now .. and the cpu usage stays normal .. usually below 50% even while heavy usage like gaming etc
but .. if i unplug the power .. while its running on battery .. even if i am not doing "anythign" .. the cpu usage shoots up to 100% within 15 seconds of unplugging the power .. and takes around 10 minutes to settle down .. even then it sometimes shoots up if i run a program .. what could be causing this problem??

Power Settings, they'll throtle your CPU while on battery to save power.
