Solution to windows update failure

Solution to windows update failure

Windows update is an automatic update tool provided by Microsoft, but some friends find that windows update fails. Why? How can this problem be solved? Next let's take a look at the solution to windows update failure.

1. Do not install any software that can fix vulnerabilities. After installing the system, you can install the software you need without affecting updates;

2. Networking, start-> Control Panel-> system and security-> click Windows Update. After entering, you will see a button on the Right To detect updates, click it to automatically start downloading and installing updates (in fact, it is suspended and not actually installed, so you don't need to touch your computer after the start to play with something else, because pending will occupy CPU resources very much and will be very difficult );

3. Wait until all the installation is complete, and it will prompt you to restart immediately. Click restart. At this time, there should be (1st stages (5 phases in total) on your screen )....) NOTE: If any optimization software is used to fix a vulnerability, there will be no words in stages, and the update will fail, and the changes will be restored several times, after five phases are completed, automatically enter the system, and then:
Choose "start"> "Control Panel"> "system and security"> "Windows Update". Click "view Update history" to check whether all the updates have been successfully installed. If some of them fail, but are not important, most of them succeed, you have succeeded.

4. You can install the optimization software, or install the software through the optimization software. (a small number of updates have a low chance of failure, at least it takes less time to fail );


Conclusion: The software is optimized to install vulnerabilities without being suspended. Install and update the software directly. That is to say, if there are too many updates (too many vulnerabilities are fixed), it is a pity that in windows update, you can view the update history, but you will not recognize it, and windows update will help you update the update as long as you connect to the Internet, that is, it will download another copy of your update content and wait for your shutdown to start the update (or application update content). Unfortunately, you have installed and succeeded with the optimization software, we also know that some software such as the framework, as long as you have installed it, will not overlap the installation for the second time, and will prompt failure. In any case, you cannot install it, and it is always in the loop, cannot be updated. At this point, you should understand that the software update windows update will not be identified. You only need to enable the automatic update and then download or apply the update and installation until the installation is successful! Why Can software be successfully updated in a small amount later? In fact, because the content is small and windows update applications produce fewer errors, the content can be easily updated.
We can also Disable windows update to prevent update failures.

Possible cause: a temporary error occurs in the network environment, or the related permissions are not enabled.

Windows update fails to report an error. Solution: Win key + R key and enter "services. msc "press enter to confirm the Background Intelligent Transfer Service, Cryptographic, Software Protection, and Windows Update Services. Enable the services and enable them automatically at startup.

Or set DNS to 4.2.2.1 or 4.2.2.2.

Alternatively, run the command prompt as an administrator, enter "net stop wuauserv" and press Enter. Then, right-click C: \ Windows and choose SoftwareDistribution to rename the folder. Enter "net start wuauserv" in the command prompt and press Enter.

Notes

Promptly update and fix vulnerabilities to avoid viruses.

CPU resources are very occupied during the update.
