When attempting to install some important updates, Windows 10 update error 0x800705b4 can sometimes occur. How to fix such a failure will be discussed in sufficient detail below, but first you need to understand what is the cause of this phenomenon, and only then make a decision on troubleshooting. Several basic methods are proposed to correct the situation within a couple of minutes, but without taking into account the virus impact, which could cause a disruption of the "Update Center" and related services.
Windows 10 Update error 0x800705b4. Reasons for the appearance
First, look at the description of this failure. When an error occurs, the system may give an additional description in the message: Something went wrong whileupdating (error code 0x800705b4), which in translation can be interpreted as "Something happened during the update." In other words, the system itself “does not understand” what is the cause of the error. In this case, the installation of updates is impossible, and all updates are blocked. By the way, Windows 10 update error 0x800705b4 on a phone running this operating system as a mobile version can also occur, and its elimination is carried out using almost the same methods that are provided for stationary systems.
As for the causes of the problem, there are three most significant ones among the main ones:
- DNS failure;
- problems with graphics adapter drivers;
- Irregularities in the operation of the Update Center.
Windows 10 update error 0x800705b4: how to fix the simplest methods?
The easiest and most accessible methods for any user are considered to be an immediate reboot of the system (if it is a short-term failure) or a rollback to a certain point when there were no problems installing updates.
But it doesn't help often, and the Windows 10 update error 0x800705b4 reappears. How to fix the situation if the cause is the functioning of the components of the DNS service? First you need to check the quality of the Internet connection itself. In the case when the whole thing is in the router, the router should simply be rebooted: first, completely disconnect it from the power supply, wait a 15-second pause andturn on again.
If that doesn't help, you'll have to check your IPv4 protocol settings and make sure all settings are set to get them automatically. For DNS servers, you can also use alternative public configurations by entering values like two eights and two fours (or vice versa), one four and three twos, four eights, etc. (this technique, by the way, is best suited for mobile devices).
In some cases, disabling the installation of updates for other Microsoft products helps (to do this, you just need to uncheck the activation box from the corresponding item in the Update Center settings).
Sometimes the Internet connection can be blocked by antiviruses or even the system's built-in firewall, so you should disable them while searching for and installing updates.
Driver and system component re-registration issues
But that's not all. One of the reasons for the failure may be a situation in which updates for the system were installed, but the video card driver was not updated, which caused a conflict, and, as a result, the Windows 10 update error 0x800705b4 appeared. How to fix this situation is probably already clear.
In the "Device Manager" you just need to update the graphics accelerator drivers yourself. To simplify such actions, it is better to use special utilities like Driver Booster, which allow you to install the latestcontrol software for all devices without user intervention, downloading drivers directly from the websites of equipment manufacturers.
When it comes to system components, the first best solution is to check them for integrity. To do this, use the command console, launched as a system administrator, in which the line sfc /scannow. is written
If the check fails, you may have to re-register one of the system components responsible for the Update Center. Again, for this you need to call the command line and enter the commands shown in the image above.
Using specialized tools
Finally, the problem of how to fix the Windows 10 update error 0x800705b4 is completely solved by using the free Windows Update Troubleshooter utility from Microsoft, which can be downloaded directly from the official website.
After its launch, existing problems will be detected and then automatically corrected.
As you can see, the tenth version of Windows, although it is one of the newest and most advanced systems, still inherited some of the failures associated with the search and installation of updates that were present in earlier modifications. And users often have to fix such problems manually.
