Additionally, only one of the tech's several so-called "fixes" corrected any of the problems permanently. Then, a couple of days after I last spoke with him, Windows Updates for Windows 8.1 finally came down the pike, I installed them, and now 8.1 is unstable, with no adjustments that I can find to correct such things as the entire Start page being transparent (intermittently?), crashing coming out of Sleep mode, newly installed games not showing up on the main Start page, desktop transparency still being too "light" or transparent even with the Personalization settings adjusted to their maximum settings, the Devices and Printers window automatically popping up every time upon reboot or Restart, and Windows (falsely?) claiming over and over again that there are hard drive problems (after supposedly "repairing" them) when there are none (unless the update to 8.1 caused them, or Windows is giving false reports of hard drive problems) [drive errors that ostensibly didn't exist in 8.0], etc.
Again, in short, Windows 8.x sucks, and just gets worse as time goes on. Furthermore, Windows is evidently getting worse and worse with each new version, and with some if not many of the Windows Updates; again, making Windows less and less worth it.
