The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work.
Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error

“Like we’ve done on mobile, DuckDuckGo for desktop will redefine user expectations of everyday online privacy,”From everything that we have learned so far, the browser will be focused on making privacy super easy and simple, eliminating tons of different settings about privacy, and making the whole environment robust privacy protection all set by default. Settings will be applied in all fields, across search, browsing, email, and more. Gabriel also said that aim of the browser is not just a privacy browser, it is meant to be built and used as your everyday browser, for everyday use that protects your privacy as a bonus. One interesting thing that was stated is that browser itself is built upon OS-provided rendering engines instead of typical Chromium. DuckDuckGo says this approach will strip away a lot of the unnecessary cruft and clutter that's accumulated over the years in major browsers. Also, the company stated that when compared to Chrome, the DuckDuckGo app desktop is cleaner, way more private and that early tests have found out that it is significantly faster as well. Is this just corporate advertising or reality? We will see once the browser is released, or once it is released for public testing. Until then take care and happy holidays.
