Size of a win 11 installation

You are missing the point. It was noted that the tablet is locked to 32-bit mode. Windows 11 is a 64-bit only OS. UEFI / MBR is irrelavant.

If UEFI doesn't work, you can install in MBR mode without any problem; the ISO in my signature works fine.

HP Stream 7 is an Intel Atom Z series 7" screen tablet with 1GB RAM and 32GB eMMC storage originally run Windows 8 32-bit, now it runs Windows 10 22H2 32-bit. I already use an SD XC card as secondary storage and have moved most of my data there but some things are still on C and cannot be moved. I have already Compact OS and compressed the whole C drive but again it is less than 200MB free, I had to manually limit the size of the swap file and disable hibernation to be able to have about 1GB free space. Every time Windows Update searches for updates it might fill the drive, so I disabled it. That's why I was amazed to see you have a less than 15GB Windows 11 installation. Apparently without any extras or updates or applications installed yet. If you add all these it should pass 20GB but still is very impressive. Imagine running Windows 11 with at least 10GB free, it would be much faster than it currently is. However HP has locked the UEFI firmware to boot in UEFI 32-bit mode only, even if the CPU is 64-bit and supports SSE4.2 to make us buy a more expensive model if we want 64-bit. I could have bypassed compatibility check and run Windows 11 25H2 now. CSM (aka Legacy BIOS mode) is not supported by the UEFI firmware, so my only choice is Windows 7 32-bit (with the hack to run in GPT UEFI mode) or Windows 8/10 32-bit. Most will say 1GB is not enough for Windows 11. Yes, I know, it is barely enough to run Windows 10 32-bit with all the updates installed, but I would do it for the experience, not for everyday use. Besides if it is already slow adding a few seconds more delay won't make noticeable difference.

PS: I have read about using 32-bit Grub or similar to run Linux 64-bit, but unfortunately this only applies to Linux. It doesn't work with Windows 64-bit. If anyone knows better, please post a guide.

PS: Yes, I know some of you would just wipe Windows and install Linux, but I don't want to do it. I prefer running Windows. I could also install some version of Android-x86 and convert it to an Android tablet, but also I don't want to do it, I already have an Android tablet. I want a Windows tablet and I cannot afford buying a new one. For checking the forum, playing some simple touch games and watching videos is perfect. I can even watch Netflix and Disney Plus if I configure the quality to standard definition. HD would not make any difference on a 7" screen anyway.

Hi

I have installed a fresh win 11.
It uses 64 GB of my drive if I just look in my computer and take properties of folders.

Is there any way to minimize those 64 GB or is all file nessasary to run win11?

As an option ,after producing the ISO from UUP Dump or downloading elsewhere ,you can take a large amount of rubbish out using NT Lite.
Then create a slimmed down usb boot disk with Rufus
