As you know, starting with the version of Windows XP, Microsoft has been constantly releasing so-called system updates and service packs. However, it is worth noting that for some reason the update error occurs in Windows 7 much more often than in other operating systems. We’ll figure out what to do about it now.
If previously system updates mostly concerned the security system, now Lately(in particular, for Windows 7) they even affect some basic device drivers, as well as specialized platforms such as the Microsoft .NET Framework, which are necessary for the operation of some programs and applications.
As for the problems, these are mainly errors from Windows 7 Update and the file itself, which is responsible for starting the process of searching for and installing updates on the system. Now we will look at the causes of errors and solutions to some of the most common problems in a little more detail.
If we talk about the reasons, unfortunately, there can be quite a lot of them. First of all, this should include a disabled automatic update, damage to the update file under the influence of viruses and malicious codes, mutual conflicts between the firewall, antivirus and update service, incorrect completion of the update process, etc.
Despite the fact that in Windows 7 the update error can be present in different manifestations, for each situation you can find the most suitable effective solution to the problem.
First, let's consider the simplest situation. It may very well be that automatic search and installation of updates is simply disabled. To check these settings, you need to use the “Update Center”, where the update method line should contain either an automatic start option or a search option followed by an installation offer.
Please note that even if such parameters are used, the system immediately begins scanning for the presence of official updates on the Internet, or rather, on the official Microsoft Update Center website, since the system initially accesses it.
If in Windows 7 there is an update error after turning on automatic mode remains, you can use a manual search.
If everything goes smoothly here and the system offers to install the found updates, you just need to click the appropriate button. If even after this the problem does not disappear, more effective measures will have to be taken.
First of all, you need to check the system disk (on which, in fact, Windows 7 is installed) for errors. For this it is better to use command line, and not the disk properties called up through Explorer. For example, in the “Run” menu you can enter the command chkdisk c: \f, which allows you not only to check, but also to automatically correct system errors.
If the error repeats over and over again, the reason for its occurrence may be that the file itself responsible for starting the update process is damaged. In this case, you need to perform a deep scan with any anti-virus software, or it is better to use utilities with the general name Rescue Disc, which are launched before the system starts from the optical media.
An equally common situation, when in Windows 7 an update error appears even after all of the above steps, is a process conflict hidden from the user’s eyes with the standard antivirus or firewall.
It is clear that the update program contacts a reliable source (in in this case- directly to Microsoft resources), so before starting the update process they can be temporarily disabled, but only if a preliminary scan has shown the absence of viruses and threats.
Now directly about the most common mistakes, not counting what was described above. Windows 7 update error codes are a fairly large database; let’s look at the three most frequently encountered ones.
Error 643 is due to the inability to update the Microsoft .NET Framework. Other components of the system can be updated, but it is its update that causes the error. You just need to remove it from the system and install it again, after downloading the latest version from the official Microsoft website. By the way, regarding uninstallation, it is better not to use standard tools from the Programs and Features menu. In this case, advanced uninstallers are useful, removing absolutely all residual files and system registry key entries from the system.
The utility is recognized as one of the most powerful programs of this type iObit Uninstaller, which has a special Forced Uninstall mode.
No less common is error code 800b0100. In this situation, the most acceptable solution would be to use automatic problem fixers such as Fix It or 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 error code 0xc0000005. It appears after updates are installed on the system. Usually, this type The errors are caused by updates in the form of packages KB2859537 and KB2872339. Removing them allows you to get rid of annoying errors.
The easiest way is to type wusa.exe /uninstall /kb:2859537 on the command line or the same thing, but only for the KB2872339 package (of course, you must log 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 recent update is causing the crashes. Now you need to remove the packages one by one, restarting the computer each time until the error disappears (you can use the same command line). When the problem is resolved, you can reinstall the updates manually, but exclude the problematic packages from the list.
Even though Microsoft no longer supports operating system Windows 7, they still release security updates for it. The question of why updates are not installed is very relevant. This article will provide answers to fix common problems.
A common reason that Windows 7 does not find updates is that auto-update is disabled in the settings. Turn on this function quite simple:
It happens that checkbox missing on the taskbar. Then you can solve the problem in another way:
You can fix the error of incorrect downloading of updates for Windows in the following way:
After this, you can restart the installation.
The reason that Windows 7 does not update may be a registry malfunction. You can fix it as follows:
Some problems with installing packages are related to the service responsible for downloading them. The failure can be resolved in several ways:
If the process fails to start again, you will need to perform additional steps:
The problems can be quite simple, for example, lack of hard drive space. For normal functioning installation services required minimum 5 GB free space.
The solution to the problem is quite simple. Requires removal unnecessary files and programs with system disk. To do this, you can use standard using Windows 7, for example, "", located in the control panel. 
Problems with the Internet connection may be the reason why updates are not installed:
It happens that problems can be caused by damage to system components. There may be reasons a bunch of:
Above are the most common errors that occur when system components are damaged. There are several methods for permission.
One of the most effective is installationWindows 7 in update mode. This option is characterized by the correction of most errors, while it will allow you to save personal files and system settings.
For this required:
When you run this command, the system will check the integrity of the files and will be able to restore them. If the data is recovered, you can run the installation again.
This crash is service dependent Microsoft NET Framework. To solve a software problem, you will need to do the following:
The second option involves removing this component and reinstalling it.
In addition to the above methods for fixing failures when installing updates system means, you can use additional software.
To troubleshoot problems, you will need the Fixit utility, created by the operating system manufacturer. It eliminates problems associated with the operation of the Update Center.
After downloading the software, installation is required. During this, the program will automatically create restore point. The utility will search for data about failures and try to fix the files.
In some situations, Windows 7 does not search for updates due to loading problems. The essence of the process is that the files are loaded into the cache memory and stored there until the user starts installing them:
To manually start, you will need to call the “Win + R” utility and enter the request “ Wuapp" In the window that opens, select "". In the “Important” section, select the first installation option. This way the user will be in manual mode install updates. 
Center Windows updates automatically searches for and installs new files, but sometimes various problems arise - files may be damaged or the center does not detect the encryption service provider. In such cases, the user will be notified of the error - a corresponding notification with code 800b0001 will appear on the screen. In this article, we will look at several ways to solve the problem with the inability to search for updates.
Owners of Windows 7 sometimes experience error code 800b0001 when trying to search for updates. There may be several reasons for this - virus infection, system problems or conflicts with certain programs. There are several solutions, let's look at them all in turn.
Microsoft has a System Update Readiness tool that checks the system's readiness for updates. In addition, it corrects any problems found. In this case, this solution may help solve your problem. The user is required to perform only a few actions:
When the utility has completed all operations, restart your computer and wait until the search for updates begins. If the problems have been fixed, then this time everything will go fine and the necessary files will be installed.
Very often, the cause of all troubles are viruses that infect the system. It is likely that because of them, some changes have occurred in system files and this does not allow the update center to do its job correctly. If the first method does not help, we recommend using any convenient option cleaning your computer from viruses. You can read more about this in our article.
Employees of different organizations are required to have the CryptoPRO auxiliary program installed on their computer. It is used to cryptographicly protect information and independently modifies some registry files, which can lead to error code 800b0001. A few simple steps will help you solve it:
Today we looked at several ways to solve the problem with the occurrence of Windows errors update with code 800b0001 in Windows 7. If none of them helped, then the problem is much more serious and can only be solved by completely reinstalling Windows.
Since the release of the first Windows 10 update, Microsoft has been very intensive in supporting the operating system. Releasing two update patches every month. One patch is for security, the second is for system maintenance (eliminating bugs, lags, interface improvements, design, etc.). However, many users have to solve problems every month when installing Windows 10 updates. After some time from user complaints, Microsoft has released a tool that fixes a large number of errors when installing updates in Windows 10/8. You can fix common error codes in Windows Update: 0x80073712, 0x800705B4, 0x80004005, 0x8024402F, 0x80070002, 0x80070643, 0x80070003, 0x8024200B, 0x80070422, 0 x80070020. We will analyze more methods than one tool from Microsoft and solve many errors when updating or installing Windows 10 updates.
Let's first look at the built-in option for correcting errors during the update. To do this, open " Options" > "Updates and security" > "Troubleshooting" > "Windows Update" and press " Run the troubleshooter".
Microsoft has released a tool to troubleshoot errors when updating Windows 10, Windows 8.1, Windows 7. I have collected all the popular ones in the system. Just follow the link and download or follow the steps below.
Sometimes it happens that the update cache in Windows 10 can be damaged, which causes a bunch of errors with various codes. This method is especially helpful when...
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msserver pause
If your process stops on the line net start msserver pause, press Enter. After successful operation, close Command Prompt, open Settings > Update & Security and click " Checking for updates".
We will fix it using the command line and the DISM parameter. Open Command Prompt as Administrator.
On the line, enter or copy the following commands in order:
After each command, wait for 100% results and do not turn off the Internet and computer from the network.
One of the common reasons that Windows cannot update or install updates may be that services are blocked by other software processes. You can try restarting your computer and freeing up some processes. If it doesn’t help, then we will analyze the method using the command BITS, stop and restart services related to Windows Update. Open command line as administrator and enter the following commands in order:
Stopping services:
Starting services:
The problem sometimes lies in the folder SoftwareDistribution, where the windows update files themselves are stored. When the system downloads updates, they are stored in that folder. After successful installation of updates, WUAgent deletes all old contents from this folder, but sometimes these processes go astray and the folder remains with different files. We will manually clean out the SoftwareDistribution folder so that there are no crashes or errors when installing windows updates. Open a command prompt as an administrator and enter the following commands:
Now let's go to the folder itself and delete all the contents in it. Navigate on your computer along the path C:\Windows\SoftwareDistribution and delete all files in this folder. If for some reason the files are not deleted, then try restarting the computer, or better yet, repeat the above steps again. After deleting the files, the problems should disappear, but as we remember, we stopped the two Update and WUAgent services, now we will start them back. Open CMD and enter the following commands:
Catroot and catroot2 are operating room folders Windows systems, which are required for the Windows update process. When you start Update Center Windows folder catroot2 stores Windows update package signatures and helps with its installation. Resetting and restoring the catroot2 folder solves many errors when updating or installing Windows 10 updates. To reset the catroot2 folder, run Command Prompt as an administrator and enter the following commands, pressing enter after each one:
Now delete all the contents of the catroot2 folder along the path C:\Windows\System32\catroot2
After removal, enter the command net start cryptsvc .
If you run Windows Update again, the catalog folder will be reset.
Do not delete or rename the folder Catroot. The Catroot2 folder is automatically recreated by Windows, but the Catroot folder is not recreated if it is renamed. If you find that the catroot or catroot2 folder is missing or not recreated if you accidentally deleted it, you can create a new folder with that name in the System32 folder, restart your computer, and then run Windows Update.
Sometimes there are situations when Windows Update is unable to download and install updates. Also, problems may arise if the update is downloaded but not installed. Most often, errors appear after reinstalling or installing the operating system, as well as in case of failures in the OS.
You may need to reset your Update Center settings to fix the errors and resume working properly.
Let's look at the most common errors.
This system failure is quite rare and difficult to correct.
Try disabling autorun different programs, on which the functionality of the system does not depend. Open "Control Panel" and click on "Task Manager". Go to the tab.
Using the correct procedure, restart your computer.
The error appears when you try to install anything on your computer. This means that there is a conflict between the program being installed and Net Framework.
First, find Net Framework on your computer. Often users delete folders and programs that they consider unnecessary, so if you don't find this software application, then most likely it has been deleted. Install again.
If the application is in place and the error still does not disappear, do the following:
We do it in the following order:
Open Notepad and copy there:
@echo off Set OSBIT=32 IF exist "%ProgramFiles(x86)%" set OSBIT=64 set RUNNINGDIR=%ProgramFiles% IF %OSBIT% == 64 set RUNNINGDIR=%ProgramFiles(x86)% C:\subinacl\subinacl. exe /subkeyreg "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing" /grant="nt service\trustedinstaller"=f @Echo Gotovo. @pause
This error most often occurs due to incorrect setting browser Internet Explorer. To correct the situation, open IE, and in it the menu "Service". After that “Browser Options” - “Connections” - “Network Settings”. Find a group « Automatic setup» and select « Automatic detection parameters". This should help the Update Center work.
Usually, this error occurs due to computer infection by viruses. Eliminated as follows:
To fix this error, you need to go to the Microsoft website. Find a list of operating systems on the website, select your operating system. Click on the + sign next to the name of your OS and select the edition that is relevant to you.
Download the program, run it on your computer, it should fix the error.
To solve this problem, you just need to download the KB3102810 update for the Update Center from the official Microsoft website. Install the update and the error will disappear.
To prevent this error from occurring on your computer again, follow these steps:
If you are trying to update your OS to latest version, then you may encounter this problem.
To fix Windows Update 7 errors, you need to repair damaged system files. Use the program for this System File Checker. Scan your computer using this tool and restart your computer. To do this you need:
