How small can Windows after XP get?

Post by LeonardoIannelliRETRIEVES »

There's this video from 2009 where Windows XP is downsized a lot, with the Windows folder being as little as 26 MB in size.



This version of XP is quite broken and lacks major UI characteristics like the Luna theme, high-res icons, Tahoma font, and graphical boot screen.

I'm wondering how much Windows Vista and later can be downsized. People have tried downsizing Windows 7 and 10 before, but I'd like to know what the limit is. How would this look? Is it as broken as XP? What's the smallest it can be before you see major breakage? And can the process of downsizing be automated, maybe even before installing the OS? All questions I'd like to see answered.

It all depends on what functionality you want to preserve. If you don't want Explorer, then this could be brought down even lower.

The newly introduced Validation OS based on build 22621 goes down to about 500 MB and that also includes WoW64. WinPE is twice as large without WoW64.

drivers themself and patches are biggest sizers
SxS can be manually filtered for barebones

Windows XP Embedded can reduced the footprint further. From a quick search, a command line only XP Embedded install will go down to 32MB. A simple GUI could get down to 128-256MB, depending on which options you choose.
