One dissonant user experience noted on Reddit encapsulates the situation well:“This problem started as soon as the updates installed this morning. Any slightly heavy applications, such as Adobe Photoshop or Audition, or games like Diablo and World of Warcraft keep crashing. The dialog box says, ‘XXX program is using too much memory and must shut down,’ even though Task Manager says I am only using 18%, and there’s over 900GB free space on the drive.”
Many users have reported their CPUs hitting 100% usage consistently, which not only slows down all processes but also leads to timeouts and unresponsive systems.
