The main workaround involves restoring AGP support files that Windows 11 dropped. A key limitation is that Windows 11 24H2 requires SSE4.2 instructions the CPU lacks, capping the install at 23H2, which only receives security updates on Education and Enterprise editions — making it a partial win, especially since Windows 7 runs faster on the same hardware. ## Full article daily.dev links to this article rather than hosting it.
