Windows updates, which are geared to give users new features, fix bugs, and deliver a whole new experience while using the operating system, can sometimes also be faulty.

Pro tip: If your computer has decreased in performance out of a sudden, there are some explanations for this phenomenon. First, it could be that junk files have accumulated in your system, making it slow. These files could also serve as hosts for viruses, which is not a good sign. Furthermore, unnecessary background apps could be draining resources that are needed for other important tasks. To fix this problem, we recommend that you download and install Auslogics BoostSpeed. This tool will delete all the junk files and disable the unnecessary background apps, making your system return to its former glory.
