In either case, Win10 22H2 or Win11 23H2, the update to Win11 24H2 is a full version change. No Enablement Package jump. Susan is still somewhat hesitant about the move to 24H2, but is beginning to look in that direction. You should update your hardware drivers before you start – particularly the video driver and any firmware updates – to avoid a BSOD. Also, you should make a full disk backup of the computer before upgrading, in case things go pear shaped and you have to go back.
You still have 4 months before EOL.
If the computer originally came with Win11, and you installed/downgraded to Win10, you shouldn’t have a problem reinstalling Win11 24H2, providing it meets the hardware requirements.
There are several ways to move from Win10 to Win11:
+ If the computer does NOT meet the hardware requirements for Win11 24H2, you will need to use Rufus in order to bypass the requirements to do the upgrade. At minimum, I believe you will need to have TPM2, SSE 4.2/POPCNT.
+ If the computer Does meet the requirements for Win11 24H2, you can use Group Policy TRV (Pro Edition only) or InControl to initiate the offer to download. Then use Windows Update, WUMgr, WUA Mgr, etc to manage the upgrade.
+ OR You can download the Win11 ISO from Microsoft download center, mount it on the running OS, and and do an over-the-top upgrade keeping your data and apps.
