When checking for updates in Windows Update of Windows 10 operating system, the following error occurred:

There were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search weh web or contact support for information, this may help: (0x800705b4)

0x800705b4 Error in WU

The only option available is to retry, but inevitable brings back the same error code and message again.

Turn out the solution to deal with this Windows Update timeout issue, at least in my case, is pretty simple – just restart the computer, and Windows Update should works normally to check, download and install updates again.

If you’re advanced user, you can try the following commands in Command Prompt with Administrator privileges and then restart the PC in case the issue if persistent:

net stop wuauserv  
regsvr32 %WinDir%\System32\wups2.dll  
net start wuauserv

If you’re encountering device driver update time-out error with same error code of 0x800705b4, such as in the case of Realtek HD Audio Driver, you can try to increase the device installation time-out instead.
