FYI, here's a snippet of the "Read Me" file that came with the update. I had to limit this to 1,000 characters...
Am I on the right track?
Lenovo System Update
for Microsoft Windows 7 and Windows 10
Version 5.07.0092
Installation Readme
Note: Microsoft .NET Framework version 4.5.2 or above is required for System Update to work correctly.
System Update downloads software, driver and BIOS updates from a Lenovo server directly over the Internet without requiring specific user knowledge of where the package is located or if it is needed by the target system.
The benifit to help you keep your system up to date and secure are:
- Provides a direct connection to Lenovo server and support
for ThinkPad and ThinkCentre drivers, software and BIOS
updates.
- Helps maximize your system performance and minimize security
vulnerability.
