Installing and Uninstalling Internet Explorer 8

Since Internet Explorer (IE) 8 is a built-in feature of Windows Server 2008 R2 there is no way to install or uninstall it using the user interfaces. Instead you need to run the following commands in a command prompt window which has administrative privileges.

If you are only having IE in your machine as an internet browser be sure to install another internet browser before uninstalling IE, otherwise you will not be able to browse internet.

  1. Click the start button and type Cmd in the search box.
  2. Right click on the Cmd icon and click on Run as Administrator.
  3. Choose the appropriate command from below for your need and copy it.

To Install -

dism /online /Enable-Feature /FeatureName:Internet-Explorer-Optional-amd64

To Uninstall -

dism /online /Disable-Feature /FeatureName:Internet-Explorer-Optional-amd64

or

FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-8*.mum /c "cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /norestart"

  1. Paste the command into the command prompt windows you just opened by right clicking and clicking on Paste.
  2. Press enter to run the command, when the command is successful you need to restart your machine to complete the action.

Rounding a value Down

If you did work with .Net Math classes you may have noted that you can quite easily round value upwards. But what about rounding values down?

For example if you tried to round the value 1.23501 into 2 decimal places using the Round method provided by the Math class as below, the result you will get is 1.24. Meaning .Net had rounded the value up.





  1. double dbl = Math.Round(1.23501, 2);




If the value is rounded down it should be 1.23, but in .Net I couldn’t find an easy way to get this done. So I did create a small code to get it done. It is very simple only a method with one statement as shown below.





  1. double RoundDown(double Number, int Digits)
  2. {
  3.     try
  4.     {
  5.         return Math.Truncate(Number) +
  6.             (Math.Floor(Math.Round((Number % 1), Digits) * Math.Pow(10, (Math.Round((Number % 1), Digits).ToString().Length - 3)))) *
  7.             (1 / Math.Pow(10, Math.Round((Number % 1), Digits).ToString().Length - 3));
  8.     }
  9.     catch (Exception)
  10.     {
  11.         MessageBox.Show("Error ! Please check values.");
  12.         return 0.0;
  13.     }
  14. }




Ohh, I think this is complicated right? Please find a bit of self explanatory code below.





  1. double RoundDownExplained(double Number, int Digits)
  2. {
  3.     try
  4.     {
  5.         // Get the whole number from the double value.
  6.         // For example we'll take Number = 788.34567 and Digits = 3.
  7.         // WholeNumberPart = 788.
  8.         double WholeNumberPart = Math.Truncate(Number);
  9.         // Getting the decimal part from the doouble value.
  10.         // DecimalNumberPart = 0.3457.
  11.         double DecimalNumberPart = Math.Round((Number % 1), Digits);
  12.         // Finding the number of decimal places so we can multiply by 10 to make it suitable for Floor().
  13.         // MultiplicationValue = 3.
  14.         int MultiplicationValue = Math.Round((Number % 1), Digits).ToString().Length - 3;
  15.         // Create the double value to round down.
  16.         // RoundedDownValue = 345.
  17.         double RoundedDownValue = Math.Floor(DecimalNumberPart * Math.Pow(10, MultiplicationValue));
  18.         // Finding the value to devide the result to make it decimal again.      
  19.         // DivisionValue = 0.001.            
  20.         double DivisionValue = 1 / Math.Pow(10, MultiplicationValue);
  21.         // Creating the decimal part with rounded down value.
  22.         // RoundedDownValue_Float = 0.345.
  23.         double RoundedDownValue_Float = RoundedDownValue * DivisionValue;
  24.         // Creating the full rounded down value.
  25.         // return = 788.345.
  26.         return WholeNumberPart + RoundedDownValue_Float;
  27.     }
  28.     catch (Exception)
  29.     {
  30.         MessageBox.Show("Error ! Please check values.");
  31.         return 0.0;
  32.     }
  33. }




The complete code of the application I created is below with a screenshot of the application running. Hope this helps to you.
