If you recently upgraded to the Windows 10 Creators Update, and you are experiencing graphical glitches such as: missing icon labels, corrupted icons or text; this is likely due to compatibility problems associated with a series of Intel Atom processors and the Comodo Antivirus utility. Prior to launch, Microsoft Support had published an advisory letting users know of a compatibility issue with Intel's Clovertrail series of Atom processors. A couple days ago, Microsoft updated their post on the Microsoft Community; including Comodo Antivirus as another cause for graphical issues some users have been experiencing.

 Icons and/or text throughout the Windows interface may not appear at all, or may appear as solid color blocks on some devices.

 This issue may occur if you have an out-of-date version of Comodo Internet Security or Comodo Cloud Antivirus running in Creators Update.  To resolve the issue if you have a Comodo product installed, please update to the latest version of the security software before installing the Creators Update.  You can find information for updating your Comodo product at https://antivirus.comodo.com/windows10update-advisory.php.
