Windows 7, although it is an improved "OS" compared to previous versions, it also constantly requires the installation of updates and service packs (service pack). And this can often cause many unforeseen problems. Now we will understand why Windows 7 updates are not installed and what to do in this situation.
Why do I need a Windows update?
Many users of computer systems with Windows 7 (or any other “operating system”) are not even fully aware of what the system update is for, considering that updates are only related to patching holes in the security system.
This is partly the case, because many attackers almost every day find gaps in it through which they penetrate other people's computers and do their dark things from a simple violation of the integrity of the “OS” and its correct functioning up to the theft of personal data (confidential information) and bringing the system to complete “crash” even with the deletion of files and folders.
On the other hand, constant updates concern all components of Windows and special platforms, during the installation of which it becomes possible to optimize the operation of the entire system as a whole. But there are some nuances and some subtleties. Now we will consider the problem of why Windows 7 updates are not installed.
Auto update issues
First you need to make sure that the automatic update option is turned on in the computer system as recommended by default, and there is no interruption in connecting to the Internet.
In order to view this data, you just need to go to “Windows Update” and in the settings settings check the line indicating the automatic update method. It may well be that this option is simply disabled.
If, in this way of asking the question, updates are not installed again , Windows 7 updates can be installed manually, since the file responsible for the automatic update may be damaged.
Manual update
If there is a problem of automatic updating, you can try to do it manually, using the search function in the same “Update Center”, at the end of which click on the “Install Now” button on the right.
If the updates are installed, then the problem is really in the update file itself. What to do with this will be said a little later, but, apparently, violations in its work can be associated with exposure to viruses or damage.
As for file corruption, the situation can be fixed by system recovery, provided that such errors have not been observed before. By the way, such a problem is often observed in situations where Windows 7 SP1 updates are not installed. The first service pack is believed to be somewhat unfinished.
Error 643
Problems can also be called frequent when Windows 7 updates are not installed (error 643) due to malfunctions in one of the main system platforms. This is the Microsoft .NET Framework (this error applies to this component).
Many users, either out of ignorance or out of habit, begin to update it manually. But this is a mistake. The fact is that the problems associated with it can really greatly affect automatic updates. There is only one way out: to completely remove it from the system (at least from the "Programs and Components" section), then download the installation distribution kit for the latest version from the official Microsoft website, and only then install it manually in the system.
However, it is advisable to perform preliminary deletion not with the help of the “native” Windows uninstaller, but with some third-party utility that allows you to delete all residual files, as well as entries and keys in the system registry in full. There are enough programs for this. For example, a fairly serious utility is iObit Uninstaller with a built-in Forced Ininstall feature.
Error Code 800b0100
Quite often, Windows 7 updates (code 800b0100) are not installed due to problems with Update Center as a whole.
In this case, it is recommended to use Microsoft's automatic scanning and error correction tools such as the System Update Readiness Tool or Fix It. Both that and other programs are very convenient in work and allow to find and fix problems in the automatic mode.
In most cases, this technique allows you to get rid of many problems, not even related to the inability to update the system. For the most part, this concerns the second utility.
Disabling antivirus and firewall
But why Windows 7 x64 updates are not installed due to any restrictions from the antivirus or firewall (firewall)?
Indeed, sometimes such situations may occur. It all depends on what kind of antivirus is installed on the system. It may well be that there is a conflict between the firewall and antivirus software.
Naturally, the update comes from a reliable source (we do not take into account the impact of viruses with request redirection yet), therefore, they can simply be turned off for the duration of the update.
If after this the update passes in normal mode, it is worth changing the antivirus or reconfiguring the firewall, adding the antivirus itself to the list of exceptions.
Viral infection
Now let's see what can be done when Windows 7 updates are not installed due to viruses or malicious codes. As mentioned above, some of them are able to spontaneously install in the "Update Center" a redirect (redirection) to another source when trying to access the update system.
It is clear that in this case it will be necessary to conduct a full check for threats, but it is advisable to turn on the in-depth analysis mode. Of course, this will take more time (up to several hours), but then you can be firmly convinced that all threats are eliminated.
If such a scan does not help, you can use the recovery disc utilities (Rescue Disc) that run before Windows starts. By the way, it is they that allow you to perform much better checks than regular antiviruses.
Afterword
If all of the above methods do not help, and the problem remains, in extreme cases, you can try reinstalling the system again, so to speak, from scratch, or use the recovery console located on the original installation or recovery disk (Windows 7 Rescue Disc - not to be confused with anti-virus utilities).
