My All-in-One Dell will not install updates, specifically KB2961908, KB2990967, and KB2919355. It just downloads, tries to install, and then uninstalls them. I have run sfc/ scannow, but it states that it could not fix some files. I've run the Windows 8 troubleshooter and it says it fixes the problem, but these updates still don't install. Malwarebytes doesn't find any corrupt files.
A website that I googled said these Windows 8.1 updates should be installed in this order: KB2919442, KB2919355, KB2932046, KB2937592, KB2938439, and KB2934018. KB2919442 is the only one that is installed on my machine. I need some guidance so I can update my desktop.
