The window previews in Windows 10 are too small to make any informed decisions. How can I increase the size of the thumbnail preview?

You can do this without any external programs by modifying the registry. According this video on how to Make Windows 10 Taskbar Thumbnails Bigger:

  1. Open registry - Win + R and type regedit
  2. Go to path HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Taskband
  3. Add new DWORD 32 Bit Value
    1. Key: MinThumbSizePx
    2. Value: Number of pixels anywhere less than 500
  4. Restart Explorer with any of the following methods:
    1. Longest - Restart Computer
    2. Medium - Log off and then log back on
    3. Shortest -
      1. Ctrl + Shift + Right click on Taskbar
      2. Select 'Exit Explorer'
      3. Pull up Task Manager (Ctrl + Shift + Esc)
      4. File > 'Run New Task' > Type explorer
      5. Voila! You've restarted explorer

  • Another fast way to restart explorer is to open up task manager. Find Windows Explorer right click > click restart. This only takes about 15 seconds total. – Azuraith Jan 15 at 14:50
