Windows XP ran on a 1 MHz processor

A video appeared on the YouTube channel \"NTDEV\", where the Windows XP operating system was run on a 1 MHz processor, which is ancient in every sense.
The processor took three hours to boot up but eventually the OS started working.
The enthusiasts even managed to perform some manipulations but after half an hour the computer showed a blue screen of death.
