Running 24H2 on Lenovo IdeaPad 120S RAM 2GB Storage 32GB

The computer was shipped with OS Windows 10 Home, RAM 2GB Storage 32GB. my IdeaPad has gotten update every year, from Windows 10, to Windows 11 22H2, 23H2, 24H2.
its RAM 2GB (un-upgradeable DDR4, soldered on motherboard) is limited from any Windows updates, freezing up forever.
its storage 32GB (eMMC, real 29.1 GB, un-upgradeable) is unable to do in-place upgrade/install. installer error message, requests 10 GB more room.

here is my way to run newer Windows OS on it.
this way applied to any PC with very limited hardware resource, couldn't perform Windows 10/11 in-place upgrade/install.

First of all, backup its files and driverbackup to an external SD card via its SD card reader. the entire OS partition will be wiped out when image restore. better let OS partition taking full disk 32 GB. you may allocate 1-2 GB for driverbackup than save them on USB drive (easy to use).
obtain a spare PC, set its hardware limited but enough perform in-place upgrade. my selection, RAM 4-8 GB, OS partition size 40-80 GB, NOT greater than RAM 8GB and OS 80GB, respectively.
clean-install Windows 11 on the spare PC. don't load any drivers. a true clean OS. my new OS size is about 15 GB under my hardware setup. its image size without boot sector will be 5.5-6.0 GB (compression ratio about 3), no matter 22H2/23H2/24H2, no significant change.
save this clean OS image (without boot sector) onto a USB drive (8GB should be ok), the driverbackup better be on same USB drive (easy to use). then restore the image on Lenovo IdeaPad 120S. over-write its OS partition only. in my install, its boot sector stays intact.
Lenovo IdeaPad 120S boot/start, it may request auto-repairing. once Windows is up, load its drivers (from early backup on USB drive or SD card).

That's it.
after new OS installed. there is over 14 GB free space on my Lenovo IdeaPad 120S. default browser is EDGE. it can take some compact software (office2010, tax return, zoom , , ,). still run fine. But Mozilla Thunderbird or Discord is no go. very slow or freezing-up.
my IdeaPad works as a home entertainment center, online TV/video, taking advantage of its HD graphics, port of HDMI/USB3.0, SD card reader. plus light document work.

I have an HP Stream 7 tablet with Intel Atom Z series (64-bit CPU but HP has locked UEFI firmware to 32-bit only), 1GB RAM and 32GB eMMC. It currently runs Windows 10 32-bit 22H2, pity I cannot test it with Windows 11 due to the locked UEFI firmware. All my applications, games and data are stored on a 256GB SDXC card. Every time I want to install a new Windows version, I must do a clean installation as you suggested because free space at best is 4GB, not enough for a proper upgrade. However, I never had to install Windows elsewhere, I make sure I enable CompactOS and disk compression and install locally. I have thought of cloning the internal storage on a USB flash drive in case I want to upgrade Windows and then clone back, but 22H2 is the last Windows 10 version, no I didn't have to. I would open the USB in a virtual machine, let it load Windows, upgrade, cleanup and clone back.

I didn't try upgrade from Windows10 x86 to Windows 11 x64. sounds impossible.

However, there is a better way to run Windows 10 x86 (my Windows XP x86 only, its upgrade did this way).
i.e. install Windows 10 slimdown. W10SD (you can google it)

my log of Windows install shows, W10SD install needs 25 GB. when W10SD install done, OS partition 5 GB. free space 20GB. (could shrink OS partition to 10-15 GB at this time when done). It's running very smooth.

W10SD runs right like XP. an OS light, compact and smooth. but W10SD supports GPT SSD modern networking , , ,

Wish Windows 11 slimdown emerged.

I want to avoid light versions of Windows because they miss features and might have incompatibilities. I prefer to use the regular version and disable visual effects (animations, fades, transparency), disable startup applications and manually disable features (so I know hot to get them back) to make it lighter myself. That said, you can remove unused system apps with Revo Uninstaller to save disk space.
