You can use its serial number to work out when it was manufactured.

For the serial number, normally the 4th, 5th, and 6th characters to reference when the product was built. The first character is the year date (Y) and the next two (WW), the week in that year it was made.

                CCSYWWZZZZ

For example Y = 8, WW = 03 which indicates your machine was built on week 03 year 2018 or from Jan. 15, 2018 to Jan. 21, 2018

If you are interested in doing an in-place upgrade from W10 to W11 24H2 on the PC as is, watch this video, which is the easiest way to do it in my opinion, and I have used several different ways to do this during the last 3 years.

How to Install Windows 11 on Unsupported PC in 2025 (New Easiest Method, No CMD)

Download the W24H2 ISO file and use that (3rd option).

Download Windows 11

You can download the free 7-Zip file utility from the link below. The top line is for 64 bit.

You'll have to repeat this procedure if and when Microsoft rolls out the new W11 builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

They have been releasing new W11 builds each October so far.

Other than that, your PC will continue to get the monthly cumulative and other updates.

That's only a minor inconvenience to have continued OS support beyond October of 2025.

If things don't work right on W11, you have 10 days to easily go back to W10 as long as you don't delete the W1 upgrade files or the Windows.old folder.
