P51 Windows 10 only?

2017-02-15, 15:19 PM

I know the P51 isn't out yet, but am I correct in assuming that Windows 10 will be the only OS option since it's shipping with Kaby Lake processors? I have to run Win7 so I'm just wondering if I should scope up a P50 before they are discontinued.

While Skylake support was extended on Win 7, Kaby Lake will only be supported on Win 10.

2017 ThinkPads will all be available with Skylake CPUs AFAIK, so the P51 will support Windows 7 (and ship with it) if you configure it with a Core i5/i7-6xxx CPU.

I was looking at the P51 with the optional Xeon E3-1505M v6 which is a Kaby Lake... I knew I read the post about the lack of Windows 7 support on the Kaby Lakes but just could not find that post.

This is not completely true.  Although some 2017 ThinkPads will have SkyLake CPU options (primarily for Win7 support), P51 is not one of them.  P51 and P71 are KabyLake only, which means Win10 only.  However P50 and P70 will continue to be sold for quite some time.

I appericate the official Lenovo response... My T540p is showing its age and it's an excuse to upgrade.

Dear someotherguy,

 

This seems strange to me.  I'm far from an expert, but would have expected that Win7 supports the full feature set of SkyLake but not the newer 'KabyLake' features.  If this is correct, I'd also expect that Win7 could be installed in a KabyLake laptop and all the user misses out on is the newer KabyLake features that are not embodied in SkyLake.

So maybe installing Win7 on a P51 would be Ok, if Lenovo was willing to do it.  In my experience installing older operating systems on slightly newer hardware has never been a particular problem, you just miss out on the newer features of the hardware, but if they aren't that important there's no problem.

 

Is this the case or is my logic incorrect?

 

(The key thing here is that I am determined to miss out on Cortana!)

 

Regards,

 

P5x_Buyer (almost)

Windows 7 may still work, provided you can find all drivers that work (Kabu lake Intel GPU somehow works with older drivers apparently), and jump through all the hoops. Even with P50/P70, where all drivers do exist, it's far from the smoothest experiences to install, because things like NVMe, USB3 and Thunderbolt didn't exist 8 years ago. 

 

But support wise, I wouldn't count on it.  Windows 7 was released in 2009, and even critical security updates for Windows 7 are only going to be available until January 2020 (unless extended again). For hardware vendor offering 3 years+ warranties this is a problem, as the software/hardware combo sold becomes impossible to fully support and maintain before the warranty expiration.
