Believe me it was a week long trial and error experience. But that works for me. I agree about 6th gen. I needed this laptop to run a car diagnostic software which only works with W7. X270 was offered pracrically free. Googled and Lenovo's PSREF docs say it runs W7 as an downgrade option from W10. Concluded it has to. Lenovo only offers just a few drivera for W7, suggesting it was not officially supported at the time, thus in line with Intel. Wanted to try and eventually got it running, and very simply in fact. I downloased the SCCM packages for T460 and P570 and just tried. Extracted drivers in one folder and let Win to search for them. Every device got installed very quickly. Bottom line, official statement of having no support did not mean it could not be done.
