From the info of the video : NOTE this is NOT my advice.. I don't recommend
registry cleaners
6 year old laptop:
Hi-Grade Notino
Windows XP Professional
Intel Celeron 1.3Ghz 512mb Ram
Cost £1199 6 Years ago
Boot Up Time 36.88 Seconds
6 Month Old Laptop
Dell XPS M1530
Intel Core 2 Duo 2.5Ghz
4GB Ram
Windows Vista Home Premium
£866 6 Months ago
Boot Up Time 64 Seconds.
Im not quite sure what this proves, il be honest the Vista laptop had a few
programs and games installed, and the XP laptop was virtually free of stuff.
But i think this shows how demanding vista is, and all the programs you
install affect the speed of the laptop. Ive wiped the XP laptop over 10times
at one point it had lots of programs installed and it took nearly 4 minutes
to boot up! So my advice is, keep your laptop clean of crap, download
cleaners to speed it up (cccleaner, regcure...) and once a while, if your
confident wipe it clean and start again (remember drivers!! )
UPDATE:
I Have recently dual booted xp and vista on the dell, with succesfull
results! Xp turns on in less that 40 seconds which shows how demanding vista
is!
