A week ago, I have just purchased a PC ex my office. The PC is Dell Optiplex 9020 using Intel i5 gen 4 processor. The PC I purchased is PC that was assigned to me in the last 5-6 years. So I know that the PC is still good and have no problem at all.

When purchased, I got everything for the PC, including monitor but excluding any OS inside it. The hard disk was wiped out, as instructed by my company to the vendor. So I bought it without an OS with very reasonable price.

To my knowledge, every PC from respective brand including Dell have Windows original in it when it was first purchased. The product key of the Windows OS is attached to its motherboard. So by purchasing the second hand PC, the Windows OS should be able to be extracted again.

But in my case, it is not that easy to extract the original OS since I did not get the CD installer of Windows when I purchased it.

So my first opinion if I want to use Windows OS, I must purchase it or I use Linux OS for free instead.

That is exactly what I did.

First time I turn on the PC, I installed it with Linux Ubuntu 20.4 to the PC. It runs successfully and very fast. I like it. No problem at all. I can use the OS. The drivers for every attached peripherals are there. No need to search the drivers. You can use it like you use Windows.
