| Windows Vista Update Package Format | Microsoft | System Files |
The MUM (Windows Vista Update Package) file extension is associated with Microsoft Windows Vista. MUM files are specifically related to the application and system updates for Windows Vista. These files contain information about system updates like feature enhancements, security updates or bug fixes and are used to keep the operating system up-to-date. They usually have numbers in their file names, indicating the recency of the update. For example, kb123456.mum, where ‘kb’ indicates that it is a knowledge base article and ‘123456’ is the actual number of the particular update.
Details and Specifications
MUM files are distributive packages that can be downloaded from Microsoft’s servers. These installation-packages are created from catalog-files (*.cab) from a specific area in the source archive (or snapshot) of the whole operating system package. To install the packages, users need to use Internet Explorer (Microsoft Windows Update uses ActiveX technology). The installation itself requires elevated privileges.
MUM files are rarer compared with other Windows packages such as executable MSI or EXE files ( .EXE, .MSI) and PowerShell ( .PS1) scripts. Other Windows file extensions related to operating systems updates include .WIM, .CAB and .XML.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .MUM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .MUM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .MUM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .MUM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .MUM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .MUM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .MUM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .MUM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .MUM file) will be extended to the maximum.
It is also good to check
- if the .MUM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
