SOLUTION: Windows 10 Start Menu text is unreadable / too dark

This problem seems to affect primarily Haswell-based notebooks with Intel HD Graphics drivers in use.  I have not yet seen it affect Broadwell chipsets, but it may.

The issue is that the Start Menu text is too dark — and in fact, it becomes gradually darker — and illegible, fading into the background of the Start Menu.  While it seems likely that a Windows 10 setting (or theme) should be to blame, it actually is neither.

The problem is the Intel Graphics driver, which includes a setting that purports to implement application-specific fixes.  To correct the problem, all you have to do is disable the setting and reboot the PC:

  1. Right-click the Desktop and choose Graphics Properties…
  2. Choose 3D.
  3. Under Application Optimal Mode, click Disable.
  4. Reboot the PC.

The problem is solved!

It’s likely in the future that Intel will correct their driver optimization presets for the Windows 10 desktop windows manager / Explorer.exe, but until that day, this is the correct workaround.
