How to install offline .NET Framework 3.5 on Windows 10 using DISM.

Windows 10 comes with .NET framework 4.5 pre-installed, but many apps developed in Vista and Windows 7 era require the .NET framework v3.5 installed along with 4.5.

These apps will not run unless you will install the required version.

When you try to run any such app, Windows 10 will prompt you to download and install .NET framework 3.5 from the Internet. However, this will take a lot of time.

You can save your time and install .NET Framework 3.5 from the Windows 10 installation media. This method is much faster and does not even require an Internet connection. Here is how to install it.

    2. Open 'This PC' in File Explorer and note the drive letter of the installation media you have inserted. In my case it is disk D:
    3. Now open an elevated command prompt and type the following command:
    Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess




    Replace D: with your drive letter for Windows 10 installation media.

    echo Installing .NET Framework 3.5...
    Dism /online /enable-feature /featurename:NetFX3 /All /Source:%setupdrv%:\sources\sxs /LimitAccess
    echo.
    echo .NET Framework 3.5 should be installed
    echo.
    ) else (
    echo No installation media found!
    echo Insert DVD or USB flash drive and run this file once again.
    echo.
    )
    pause

    Download.

    The file will install .NET Framework 3.5 automatically after finding the drive letter of your Windows 10 installation media.

    How to change the size of the touch and on-screen keyboard in Windows 10

    Windows 10 PCs come with two keyboard apps, one is the OnScreen Keyboard , and the other is the Touch Keyboard . Basically, you don't need a touch screen to use the on-screen keyboard.

You can move or enlarge the virtual keyboard from the icons in the upper right corner. If you want, you can also easily resize it. Changing the size of the on-screen keyboard is very easy. Type On-Screen Keyboard in your Windows search and run the desktop app, or you can also go via Settings > Ease of Access > Keyboard> Turn on the On-screen keyboard.   To change the size of the on-screen keyboard, move the cursor to the corner and drag it to the desired size.

    Designing the Windows 8 touch keyboard.

    When we began planning how touch and new types of PCs might work on Windows 8, we recognized the need to provide an effective method for text entry on tablets and other touch screen PCs. Since Windows XP SP1, which had Tablet PC features built in, Windows has included a touchable on-screen keyboard. But those features were designed as extensions to the desktop experience.  For Windows 8, we set out to improve on that model and introduce text input support that meets people’s needs, matches our design principles, and works well with the form factors we see today and expect to see in the future. I’m writing this blog post on our Windows 8 touch keyboard using the standard QWERTY layout in English. As I look at it, the keyboard seems very simple and sort of obvious. This comes partly from having worked on it for a while, but also because keyboards are familiar to us. But there is more here than meets the eye (or, fingertips). We started planning this feature area with no preco...
