HP is bad about putting a lot of extra software on their machines, and they have this security suite of utilities that I always uninstall when I am configuring a new PC. Once I got all that old stuff off, I installed things like Office 2007, Adobe Acrobat Reader, Symantec Antivirus, Windows Defender, and so on. Afterward, the hard drive was very heavily fragmented so I defragged it.
Performance on this machine is impressive. Opening and closing Office 2007 applications just takes a few seconds. At my work, we install the same basic software package on most every PC, and I noticed things like Java and Acrobat Reader, which usually take a minute to load, went very quickly on this notebook. All the while I was loading it up and running the defragmenter, this computer was exceptionally quiet, and I didn’t notice any large amount of heat coming from the top of the machine or through the keyboard.
