Anything less is too little to boot Windows 10. Microsoft's official minimum memory recommendation is 1GB. Interestingly, Windows 10 could partly boot with 140MB, but that proved to be too little for the UI to run.
The experiment was performed using a virtual machine. Booting took about three minutes and with 192MB of memory the system was very unresponsive.
Yesterday, 16-year-old Twitter user @0xN0ri (Nori for short) posted a thread where they continually tried to run the 32-bit version of Windows 10 on smaller and smaller amounts of RAM, using the operating system’s 1909 November update as a base and running it on Oracle VM Virtualbox off what they told Tom's Hardware was a Dell Inspiron 3670 running Arch Linux.
It works! https://t.co/6wotLMV8Yt pic.twitter.com/zyNQqtlVMI
