Open alternative to Windows
“if it can run windows exes out of the box, whilst not phoning home to microsoft, it becomes an attractive proposition”

What people warn about
Each mark is one comment
Not stable enough for daily use
“the hard part is the compatibility (that is given by many still missing parts) and stability (the still defective parts)”
Comment from 22 Jan 2026 in “30 Years of ReactOS” “in some ways it's closer than it feels to being acceptable as a daily driver, in others it's quite far away”
Comment from 23 Jan 2026 in “30 Years of ReactOS” “Still not nearly stable enough to be used as a daily driver, but it's been getting a lot better lately.”
Comment from 23 Jan 2026 in “30 Years of ReactOS” - Comment from 22 Jan 2026 in “30 Years of ReactOS”
Little practical purpose beyond replication
“solves for a very small set of practical use cases which are not covered by real Windows, or Linux+WINE”
Comment from 22 Jan 2026 in “30 Years of ReactOS” “if there was a purpose for it besides having an "is able to" replica, it would attract more people.”
Comment from 22 Jan 2026 in “30 Years of ReactOS” “best viewed as an enthusiast research / challenge project with no practical use”
Comment from 22 Jan 2026 in “ReactOS Celebrates 30 Years in Striving to Be an Open-Source Windows” Slow development and little interest
“ReactOS has been very slow to develop, and probably missed the point where it could make an impact.”
Comment from 22 Jan 2026 in “ReactOS Celebrates 30 Years in Striving to Be an Open-Source Windows” “Development on the project has never been fast but somewhere around 2018 it dropped even more”
Comment from 22 Jan 2026 in “30 Years of ReactOS” “there's never been enough interest in ReactOS to get it to the point where it's stable”
Comment from 15 Jun 2026 in “ReactOS (FOSS "Windows") achieves 3D-accelerated Half-Life on real hardware”
