X200 with Windows 10

With Windows 10 you can install Office 2019. Windows 7 can only install Office 2016.
However, some devices do not work with Windows 10, whereas all devices function with Windows 7 with all drivers provided by Lenovo.

Disable Intel AMT so that the PCI to Serial device is gone from the device manager.

The SD card reader works perfectly. I did not install any driver at all. Windows 10 did everything. It installs it as a RICOH device, not as a generic SD card reader in the DELL E6420.

 

Fingerprint

The fingerpint works using using Windows 7 version downloaded from Lenovo archive of drivers at:

Run all Windows 7 version of drivers as administrator in Windows 7 compatibility mode. Some worked while others don't. We need to experiment all the time.

Follow the instruction mentioned in the above link. Do not use Windows 10 Hello to login. The Windows 7 fingerprint software creates another user for logging in using fingerprint.

System Update is Useless

System Update is extremely useful for Windows 7 drivers, unlike T60 which is unsupported. I installed them one by them so that I may know if there are problems.

 It turned out that one is having problems. It has to do with the way the mouse functions but when I installed the communication software, I was able to install all drivers. The communication software insists on installing the tablet button driver which cased problems when installed alone.

Upgrade

Notice that I use an Intel SSD pro 1500 180 GB drive and 8 GB RAM in dual channel mode.

Be careful when instaling the RAM. Only certain types will work so we need to experiment.
