Read http://reviews.cnet.com/5208-7813-0.html?forumID=32&threadID=119247&messageID=1353529 and use the tool there to discover what you've stowed on the hard disk without knowing.
And this is the tip of the iceburg.
As to Office 2003, if you are like most, you'll get more cash by selling that seperately. If you were to leave it on the machine, the person may think you sold it to them and will create headaches when they demand the license transfer. That office alone may be worth hundreds.
-> I suggest a disk wipe and using the restore CDs that came with the machine. Don't install any software that you won't be giving them the CDs and Licenses to.
I have replaced my 5 year old Sony FX 170 running Windows ME with a new, faster notebook running XP. I want to sell the Sony, probably on eBay, but first want to erase or clean off all data and programs that I would not want to fall into the wrong hands. I know to erase the files in My Documents, but what else? I would like to leave as many of the programs I have installed, such as Office 2003 and Quicken, as possible as it would probably make it easier to sell, but I don't want to leave anything that could cause me trouble. Is there a guide for this process somewhere? Is there a program that will do it or make it simpler? Thanks for any help or suggestions.
