Microsoft Windows 10 upgrades and 'refresh' reinstalls waste a stack of time, although at times neccessary as a result of winrot.
Here's a couple of routine steps to quickly run through afterwards.
- Install Lenovo Vantage from Windows Store. Install the system interface package as requested by the app.
- There's an Intel CPPC driver from the Lenovo website. idk but seems okay to install. Note https://support.microsoft.com/en-au/help/2878342/cpu-frequencies-shown-in-system-property-page-do-not-match
- Remove InstantOn driver manually. Seen some crash dumps from it in the past.
