Enough bull-shit here’s the short version 🙂
Speed up your 8 year old computer, by arranging your process priorities.
To Optimize PC Performance
1 – Create a new user account, move Desktop/my documents, and files you need then delete the old one
2 – Clean up %temp%, registry, and defrag our computer thoroughly with a Ultimate Defrag software.
To optimize internet.
1 – Use Chrome, disable all plugins
2 – Put chrome on high priority
1 – use Firefox, with priority above normal on plugin-container.exe and flash processes.
3* (in both cases) disable high process usage software
disable file sync (dropbox, skydrive, google, drive.. etc )
disable torrent applications
disable messengers (skype and live will still operate in livecomm.exe less process in win8)
