Experienced PC and Internet user
As you know, starting with Windows XP, Microsoft has been constantly releasing so-called system updates and service packs. However, it is worth noting that in Windows 7, for some reason, the update error is much more common than in other operating systems. What to do with it, we will now figure it out.
Why does Windows 7 need an update?
If the error occurs again and again, the reason for its appearance may be that the file itself, which is responsible for starting the update process, is damaged. In this case, you need to perform a deep scan with any anti-virus software, but it is better to use utilities that have the general name Rescue Disc, which are launched even before the system starts from optical media.
Firewall and antivirus issues
An equally common situation, when in Windows 7 an update error appears even after all of the above actions, there is a process conflict hidden from the user's eyes with a regular antivirus or firewall.
It is clear, after all, that the update program refers to a reliable source (in this case, directly to Microsoft resources), so they can be temporarily disabled before starting the update process, but only on condition that the preliminary check showed the absence of viruses and threats.
Error after Windows 7 update
Now directly about the most common mistakes, apart from what was described above. Windows 7 update error codes is a fairly large database, let's look at the three most common ones.
Error 643 is related to the inability to update the Microsoft .NET Framework. Other components of the system can be updated, but it is her update that causes the error. It should simply be removed from the system and reinstalled, after downloading the latest version from the official Microsoft website. By the way, with regard to uninstallation, it is better not to use the standard tools from the Programs and Features menu. In this case, advanced uninstallers come in handy, removing absolutely all residual files and system registry key entries from the system.
One of the most powerful programs of this type is the iObit Uninstaller utility, which has a special Forced Uninstall mode.
No less common is the error with the code 800b0100. In this situation, the most acceptable solution is to use automatic problem fixers such as Fix It or the System Update Readiness Tool. In most cases, they are able to fix problems automatically, even without user intervention.
But the biggest headache for many users is the error code 0xc0000005. It appears after installing updates to the system. Typically, this type of error is caused by updates in the form of packages KB2859537 and KB2872339. Removing them also allows you to get rid of annoying errors.
The easiest way is to type in the command line wusa.exe /uninstall /kb:2859537 or the same, but only for the KB2872339 package (of course, you must be logged in as an administrator). If this does not help, you will have to use the update log, in which all packages should be sorted by date. Most likely, some latest update is causing the crashes. Now you need to remove the packages one by one, each time restarting the computer until the error disappears (you can use the same command line). When the problem is fixed, you can manually install the updates again, but exclude the problematic packages from the list.
If an unknown error appears when updating Windows 7 and even the new Windows 10 Code 800B0100, then usually after that the Update Center will no longer work until you fix it. At the same time, it was not possible to find any clear reasons for the appearance of the problem. The only likely reason why error 800b0100 appears when updating the OS is a corrupted file that was loaded by the Windows Update service and for some reason did not load or did not load completely. Restarting the computer usually doesn't work. What to do in this case?
Method 1
First, you can try to force Windows to download the update files again. To do this, launch a command prompt with Administrator rights and enter the following commands one by one:
Net stop wuauserv cd %systemroot% ren SoftwareDistribution SoftwareDistribution.old net start wuauserv
What have we done? Stopped the Windows Update service, went to the Windows folder and renamed the folder Software Distribution V SoftwareDistribution.old. After that, the update service was launched again.
Now you need to search and install system updates again.
Method 2
If the proposed solution did not help, then download a special diagnostic program from here and run it.
The utility should check the operation of the Update Center, find an error and fix it. As a rule, it helps in 75% of cases when error code 800b0100 appears when updating Windows.
Method 3
If none of the proposed solutions worked, then we launch the Windows command line again and execute the commands in turn:
DISM.exe /Online /Cleanup-image /Restorehealth sfc /scannow
It will look something like this:
Let me explain what we did. Deployment Image Servicing and Management System First DISM will check and fix the failure of the system using the Windows Update service. And then a full check and restore of system files will be carried out using the second command. As soon as it works, you need to start the Update Center again. Error 800b0100 should no longer appear.
Note:
If the DISM utility gives an error when executing the command, it means that it cannot fix the problem automatically. In this case, you will need to find and download the original Windows installation image, burn it to a disk or USB flash drive so that the operating system sees it. After that, in the command line with administrator rights, you need to run the command:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:E:\RepairSource\Windows /LimitAccess
Here is the key /Source specifies the path to the \RepairSource\Windows folder on the installation disk. I have this drive E: \, you may have a different letter - be sure to consider this point!
