This can be achieved with a small batch file that will create a list of all installed Windows hotfixes and the date and time that they have been installed on the system. The information is taken directly from the KBxxxxxx.log files that are created for each individual hotfix that is installed in Windows.

Those log files are located in the Windows directory and it would take some time to check them manually to build the list. Here is a screenshot of the output which is saved in a text document in the root directory of the main hard drive.

The code which has to be added in one line is the following:

dir %windir%\*.log /o:d | findstr /i /r /c:q......\.log /c:kb......\.log /c:q......uninst\.log /c:kb......uninst\.log > %systemdrive%\hotfixes.log

Some of you might prefer a direct download, just download the knowledgebase file and unpack it to the computer system. It contains the same code that is shown above.
