Curious. I know that it's possible to run Windows 7 64-bit on Ryzen 1000-series, was thinking of trying it out.
W7 Compatibility Rundown:-
Skylake onwards changes how USB devices are "presented" to the OS (EHCI -> XHCI). W7 installer natively has the former but not the latter.
- Sky/Kaby Lake work fine (inc HD630 iGPU) but needs slipstreamed USB XHCI drivers
- Coffee Lake v1 (Z370) works as the chipset is Kaby Refresh, needs same slipstreamed drivers
but the UHD630 iGPU doesn't work (no driver) and will require a dGPU
- Coffee Lake v2 (H310/B360/H370/Z390)
doesn't work as the new chipsets are Cannon Lake and breaks USB completely (USB is completely non-functional even after slipstreamed drivers). New Intel networking chips (eg, CNVi Wi-Fi) lack W7 drivers too.
- Coffee Lake v3 (H310C / H310 R2.0). Intel have replaced the first H310 (14nm) chipset with H310C or "H310 R2.0" (22nm). A quick look at ASUS range, eg,
PRIME H310M-A R2.0 shows they have full Windows 7 drivers for both 32 & 64-bit. (Thus proving that Kaby / Coffee Lake's W7 "restrictions" were totally fake all along...)
- Ryzen 1000 CPU's work with slipstreamed drivers. All drivers are present on many B350 / Z370 boards
- Ryzen 2000 CPU's can also be made to work but B450 / X470 may lack drivers for new Intel CNVI Wi-Fi / I211 Ethernet chips. Some boards with older AC7260 / I219V Intel or Realtek based LAN chipsets, eg, Gigabyte B450 AORUS M, appear to have all W7 drivers present. Likewise B350 / X370 + BIOS Update + Ryzen 2000 will probably work if drivers are present.
- Ryzen 2200G / 2400G APU's don't work and fail to boot with ACPI errors. Even early 2015-2016 W10 builds have serious stability issues.
Raven Ridge is W10 1709 minimum.
- Use WUFUC to re-enable MS's artificially crippled security updates for Kaby / Coffee / Ryzen
- Slip-streamed utilities are still available for download (
ASUS,
ASRock,
Gigabyte,
MSI). New versions add NVMe support (inc KB2990941 and KB3087873 hotfixes). They'll create either a USB boot stick or an ISO for DVD-R burning.
- Many motherboards have a BIOS option (eg , XHCI Handoff or PS/2 simulator) to bypass the lack of XHCI USB during install without needing to slipstream drivers
- Alternatives include
1. Use an actual PS/2 keyboard + SATA optical drive to install W7 then install XHCI USB drivers off motherboard DVD-ROM driver disc / pre-downloaded to a secondary internal SATA HDD. Once installed you can switch back to USB.
2. Set up an unattended installation (inc USB drivers) from a SATA optical drive.
Starting to think that adopting Windows 10 was a mistake.
Join the club. I found 2016 Enterprise LTSB the only tolerable version that doesn't break every 6 months and actually feels like you're using your own PC and not borrowing someone else's 27" mobile phone. Of course, it's also the same one not available to consumers so instead of 'encouraging' people to use the regular Home / Pro bi-annual train-wrecks, half the population instead remains on W7...
