    All Windows versus except for XP suck ass. Get a clue and bring back the OS Bill Gates admitted to making a mistake when he decided to
    no longer support it.

    This worked great for me and fixed a problem I’ve had for months — the April 2014 roll-up update KB2919355 persistently failing to install. Now all is well. Many thanks!

    You might want to also mention that the original Windows installation is left over from this procedure, on the boot drive, called, Windows.old. It can be safely deleted in due course I’m sure.

    windows is rubbish. all the years they have been developing and still no better !! Constant errors, repairs, trouble shooting. Money for rubbish.

    I upgraded from Windows 7 to 8 and then updated to 8.1. I have no DVD containing 8.1 and the product key is for update only – not installation. This means that even if I pay for an installation DVD it is useless. I also have removed my Microsoft Account which should not be necessary to run MY computer. All this means that there is no option to repair Windows. My dealings with the tech. chat line suggest they take people through irrelevant hoops and after making the problem seem very complicated they ask for money. Windows 8.1 seems to become corrupt using very popular software and the tecks. appear to have no idea what to do. I have found several instances of problems I have solved myself involving a simple adjustment after being told the problem required in depth investigation. Like John above I will be seeking alternatives to Microsoft ASAP

    Machine had Win 8.0 as an OEM preinstall … no install disk
    Upgraded to Win 8.1 via Windows store … no install disk, no reinstall option

    This is now the norm for Windows.

    Please update you article with the alternate procedure for users of preinstalled Windows
    To help with this update is this reply from a Microsoft employee on a Microsoft forum

    1. Are you facing any issue with the Windows 8.1 Operating System?
    2. How did you install Windows 8.1 operating system?

    You can go to the Buy Windows page and get Windows 8.1, if you don’t want to download, you can buy Windows 8.1 on DVD from a participating retailer if it’s available in your country or region.

    Windows 8.1 has in-built troubleshooter (Repair Windows) which will help us to repair the operating system.

    You may refer to the following Microsoft article.

    How to restore, refresh, or reset your PC

    While performing Refresh: The apps that came with your PC or you installed from Windows Store will be reinstalled, but any apps you installed from other websites and DVDs will be removed. Windows puts a list of the removed apps on your desktop after refreshing your PC.

    While performing Reset: All of your personal files will be deleted and your settings will be reset. Any apps the came with your PC will be reinstalled, but all other apps will be removed.

    When you perform System Restore to restore the computer to previous state, programs and updates you installed are removed.

    The kinked information page is:

    If you see “You cannot refresh without losing user data because User Account Control requires notifications” … use search to find User Account Control settings and lower it so that it reads “Allow Windows Updates” … then go back to the Metro style Restore page ([Charm menu]Settings->Change PC Settings->Recovery->Refresh Your PC Without Affecting Your Files”
    Click the “Get Started” button and follow the prompts.

    There is also a command line alternative that uses a built in system file repair, but keeping this simple.

    So, I installed 8.1, hoping it would calm down the farce that is Windows 8 and now I cannot boot my BRAND NEW Alienware 17 laptop!! It says the issue is in a windows system file. Alienware refuses to assist me, putting my one year warranty to waste, and insists that I can only go to Microsoft with this issue because the OS is the problem and Alienware (and my approximately ONE MONTH old system) doesn’t support 8.1. I cannot afford to pay for Microsoft service, so I am either stuck with a broken computer or returning a brand new one. Either way, Microsoft, you need to get a clue. No one likes this OS – not everyone is going touch screen and this OS shouldn’t even be available on systems that aren’t touch screens! I am disappointed in your company and the Alienware corporation as well because you both promised and didn’t deliver. I’m sick of having to troubleshoot my way through everything.
