Often, many Windows users who have problems installing critical updates for the system or additional service packs turn to Microsoft for help, which allows them to install updates, so to speak, bypassing the built-in Update Center. In the case of the seventh OS modification, the most optimal tool is the so-called standalone Windows 7 update installer, which, however, is not included in official assemblies, but can be downloaded and installed separately. Next, we will examine how this applet works, and also dwell on some types of the most common errors and methods for eliminating them.
What is the standalone installer for Windows 7 updates?
By itself, this tool is a universal tool that allows you to install update packages manually downloaded by the user in CAB and MSU formats, without having to connect to the Internet, as is required in the case of a “wired” update tool. The essence of using the standalone update installer for Windows 7 is to install the program as an additional toolkit, and then use its own service to install updates, which works either in the visible or in the background (it all depends on how it is started initially).
How it works?
After the installation, you can start the Windows 7 Update Tool applet either directly using the graphical mode or through the command console, in which additional launch attributes as the basis of the start command can change the operating mode (for example, transfer work to the background, hide notifications when the update packages are installed and etc.).
The Windows 7 stand-alone installer update service (Wusa.exe) itself, after starting, first reads the “Update Center” metadata, then analyzes the update files of the above formats and copies them to the so-called sandbox or protected folder, then calls the API function for the “Update Center” and after the installation is complete, it returns the code.
Download and install applet
It is recommended that you download this toolkit directly from the official resource of the developer corporation, taking into account the architecture of your own "seven", which equally applies to the subsequent download of important updates. The size of the loaded installer has a volume of about 680 MB. For installation, as usual, the start of the file is used on behalf of the administrator, after which you only need to follow the instructions of the installer and wait for the process to complete.
Now, if you already have downloaded updates, the Windows 7 standalone installer service can be started just like any other stationary program, or you can use the command line where the main command (Wusa.exe) is written, which can be supplemented with attributes. You can get complete information from them in the help system of the command console by entering the combination wusa.exe \ ?.
The most common errors in the installer
Alas, like many other Microsoft software products, this applet is not immune from errors.
The most common messages are the deactivation of the service, as well as errors of the standalone installer of Windows 7 updates 0x80070424 and failures with similar numbers starting with a combination of 0x80. Almost all errors boil down to the fact that for the specified applet, its own service running in the background was deactivated for some reason, because of which the start of the main tool is impossible.
Methods to fix Windows 7 "Service Disabled" offline installer crashes and similar errors
To eliminate startup problems related to an unexpected stop of the main service, you need to call the services section (services.msc), find the desired process in the list, double-click to open the parameter editing window, start the service by pressing the corresponding button and set the start type to automatic (but not deferred ), then save the changes.
Similarly, you can fix the problem through the command console, which will need to be run exclusively on behalf of the administrator.
First, the sc config wuauserv start = auto combination is entered, which puts the process in automatic mode, and then the sc start wuauserv command is entered , which directly activates the service itself.
In the event of an error of the standalone installer of updates of Windows 7 0x8024800c, the net stop “Windows Update” command is written sequentially (exactly as shown), then the SoftwareDistribution folder located in the root of the Windows directory is deleted, and then the service is restarted by entering net start “Windows Update ”.
Note: if the above folder is not deleted for some reason, you can use disk cleanup to delete system files or unlock the directory using the Unlocker applet. You can also change the owner of the directory in the folder properties, but this is far from the best way, besides requiring more time to perform the basic and all related operations related to setting a full set of access rights.
