Microsoft provides a tool to check out your machines to see if they are Win. 11 ready (I do not have a link handy but it's easy to find) and none of mine are for the reasons @roamer_1 has alluded to. You should also know that not all current processors make the grade.
Just my own personal opinion, but it appears to me that Win. 11 is more of a tool to sell new machines than a big OS upgrade.
Yes
@Bigun , your machinery is very likely UEFI and TPM2
capable... It/they are a setting in BIOS... So yeah you probably can set the machine up to take Win11. What you need to understand to make an informed decision is what will happen in order to make your machine UEFI/TPM compliant, and that is:
You will need to save everything off the machine, Jst like you would for a HDD replacement or other major data-loss surgery. I would suggest simply buying a new HDD and leave your old one alone in case of some SNAFU.
When your data is guaranteed safe, change your BIOS to UEFI and (Likely) within UEFI, enable TPM2
After reboot you will be ready to install windows from a UEFI capable thumb, which must be prepared before the fact. I have not been successful installing Win 10 into UEFI using a standard bootable windows media. I DL the ISO, set up a UEFI bootable using Rufus (
https://rufus.ie/en/) creating a UEFI/GPT/NTFS bootable and importing the Win10 ISO into it.
Then boot to the thumb and install normally.
IOW, It is a complicated thing to do and ma really be an onramp to horror highway. It is still largely experimental to me, still messin with it... And maybe I am overly cautious... But so far, it ain't been fun.
