This article gives a class that extracts Windows XP hotfix installed on a computer.

What does the code do

This class extracts Windows XP hot-fix installed on a computer.

Enumerate all entries of the registry key: "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\HotFix" and focalize on the value "Fix Description".

How to use it

It's simple :). Declare an object of the CXP_Hotfix class, named "hf".

CXP_Hotfix hf;

Now we can use it in, here is a little example:

int nb_hotfix;
nb_hotfix = hf.m_aHotFix.GetCount();

if (nb_hotfix > 0) // display only if there is at least 1 Hotfix
{

    // loop until we find an Hotfix and display it (them).
    for (int a = 0; a < hf.m_aHotFix.GetCount(); a++)
    {
       printf("%s\r\n", hf.m_aHotFix[a]);
    }

    printf("\r\n");

    // here we show number of Hotfix found.
    printf("Found %i Windows XP Hot-fix installed.\r\n\r\n",
                                   hf.m_aHotFix.GetCount());
}

else // No Hotfix was found.
{
    printf("No Windows XP Hot-fix installed.\r\n\r\n");
}

That's all.

Inspirations

I had the idea to write this code when I saw the code of Robert Edward Caldecott's to get the list of installed applications (CinstalledSoftware).

Restrictions

This code runs well on Windows XP SP1; for other Windows versions, I don't know, sorry..
