Hello,
Sorry to hear you are having issues. Need more information.
1) Windows 10 full version numbers. Please use Winver.exe for full version numbers.
2) Icon Packager version numbers.
3) When you applied the "Windows Default Icons" by Microsoft. Can you post your Windows Explorer screenshot to see if it indeed be blank or back to default Microsoft Windows icons set.
Thanks
