How old is my computer?

I have been given the task of determining the inventory of computers for my company - one question is how old is each computer.

Is there someway to determine the approx age of the computer or maybe when it first had windows installed?

When it first had windows installed - look at the creation date of the Windows folder - WINDOWS for XP, WINNT for 2000/NT.

If you have Dell systems and possibly other major brands, you can often look up the system information including the ship date by just referencing the serial number.

This is an interesting task. If these are name brand computers (Dell, Compaq, etc...) There may be a sticker on them with a date. One other thing you could look at would be the hardware itself. Sometimes certain parts will have dates on them. I would look at integrated parts first unless it is a Dell in which case you can go to the Dell Web site and type in the service tag number and it will say when it was purchased.

If this is a custom build from a local shop, sometimes they will place a sticker inside the case so if the machine comes back for warrenty work they will know if it is qualified for free service.
Almost every major manufacturer maintains a database with system serial numbers, and data on that system.  For example, with a Dell service tag at, you can look up warranty info, original system configuration, ship date, invoicing, and all kinds of other stuff.

There should be a sticker with the serial number/service tag on the computer somewhere.

FYI, normally you access the database at
