That's not really 100% possible.
I'd do a clean install of XP from the CD, let it run through all Windows updates (takes some time!), install a free antivirus and either install MS Office (using the original CD and the original license code, that Belarc can find for you) or - if you don't have that CD anymore - OpenOffice.
Without knowing what CD's you lost it's impossible to recommend replacements. But may I remark that it is bad systems management if you have no CD, but are still using those programs on other PC's in your small business. If you don't use them at all anymore, why care about them?
Good Afternoon! We recently took a computer out of our network in our small business. I would like to give the computer to an employee but before I do that, I want to make sure everything is wiped off of it. I don't want to lose the additional programs we've installed, like Office, but I don't want logins or settings or files to go home with the employee. Also, this computer is rather old and we no longer have the CDs for the programs. Is this possible to do with these restrictions? And if so, what do I need to do? Big THANK YOU in advance!
