A remarkable achievement has emerged in the tech community, as a bootable version of Windows 7 has been crafted to occupy a mere 69MB of disk space. This innovative feat is the brainchild of Xeno, a seasoned Windows Insider and code enthusiast, who has meticulously configured and pruned the system files. However, potential users are advised to approach this release with caution, as it is more of a “fun proof of concept” than a fully functional operating system. Significant work remains to be done to ensure compatibility with most Windows software packages, although Xeno has hinted at the possibility of further developments.
I have released a 69.0MB version of Windows 7 x86. You will need to provide your own system files to get even some of the most basic programs running. File list: https://t.co/xAqTob4uPxDownload: https://t.co/v5CdxtRZre pic.twitter.com/8GcQjRDcjnOctober 29, 2025
The accompanying desktop screenshot serves as proof of the operational Windows 7 system. For those intrigued, the embedded Tweet includes a link to download the installer, which is a 7zip compressed file of 40.4MB hosted on Archive.org. Inside the archive, users will find a compact VMware virtual disk along with a configuration file.
Windows 69?
Interestingly, this version of Windows raises eyebrows with its potential for generating the notorious “This copy of Windows is not genuine” notification.
Useful version on the way?
While the tech community often embraces impractical or whimsical software and hardware projects, Xeno has received encouragement from fellow Twitter users to refine ‘Windows 69’ into a more usable version. Currently, the operating system is limited in functionality, as Xeno acknowledges that “virtually nothing can run due to critical missing files such as common dialog boxes and common controls.” However, there is a glimmer of hope, as Xeno suggests that an enhanced version with essential system files could cater to users interested in running older games and applications. “There seems to be genuine interest in this,” Xeno notes, likely spurred by the enthusiastic response to this initial release.
A casual examination of the 295 files included in the installation reveals that many, including a dozen log files, may be superfluous and could be eliminated. Xeno also mentioned in the Twitter thread that “there is definitely a ton of room you can save,” indicating further opportunities for optimization.
With time and careful adjustments, it remains to be seen whether the necessary files can be added to transform this into a more practical version of Windows 7, potentially maintaining a similar compact size. The tech community is eager to see if this endeavor will lead to a series of Tiny11-style Tiny7 releases.
