Adjust the Date and Time
Microsoft updates its Operating systems according to DST and TZ. If the date, time, and time zone of your computer are incorrect, you are likely to face issues while installing the recent updates. Here is how you can adjust the date and time on your PC:
Run Windows Update Troubleshooter
Additionally, you should run the Windows update troubleshooter if you encounter the 0x800705aa error code. Windows has a variety of tools that can be utilized for troubleshooting several problems that you may encounter. Among these tools is the Windows Update troubleshooter, which is designed specifically to solve problems with updates. Hence, you can run the update troubleshooter and see if it can find and fix the problem. Follow the steps below to do so:
Reset Windows Update Components
When Windows is updating your computer, it uses multiple services for that purpose. In the event that any of these components responsible for updating your system fails to operate correctly, the updates will not be installed, leading to errors like the error code 0x800705aa. To resolve the situation, you would need to reset your system update components. This will revert the update components to their original, error-free state, thus resolving the error in the process. Here is what you need to do:
Run SFC and DISM Scans
If the Windows Store troubleshooter failed to fix the issue, then you can also try running the SFC and DISM commands. Both are built-in utilities to resolve errors like the one at hand. Most cases of file corruption can be resolved by running the SFC and DISM utilities, which is why we encourage you to give it a shot. Hopefully, it will resolve the issue in no time.
Free Up Drive Space
If you don’t have enough space on your computer’s hard drive, you won’t be able to install the latest updates. If this scenario is applicable, freeing up drive space can help you resolve the error code 0x800705aa in Windows 11. Essentially, when you free up disk space, you get rid of unused files and fragments of data on your hard drive. This helps your computer run efficiently and allows you to install more programs and their updates without any issues. Follow these steps to free up drive space on Windows 11:
Install the Updates Manually
Another way you can work around this issue is to manually install the update causing the problem. Any update that is causing you trouble can be downloaded from the update catalog, then installed manually. Essentially, this is just a workaround to address the error code and not a troubleshooting method.
Clean Boot Windows
In some cases, a background application prevents you from performing your day-to-day operations on your system, which includes installing the latest updates. This might be true in your case too, which is why we suggest troubleshooting in a Clean Boot state. A clean boot allows you to test whether a background program interferes with your game or program by starting Windows with just a few drivers and startup programs. However, before you proceed with clean boot, try launching Windows in Safe Mode and repeat the action that caused the error. If the issue does not occur in Safe Mode, then perform a Clean Boot.
Repair Install or Clean Install
At this point, if none of the methods described in this article has worked for you and you are still unable to install the update, you have no choice but to reinstall the system files. You can do so via Repair install and Clean install. Clean installing – You will reinstall Windows with this method. This is a good method if you want a fresh start. Nevertheless, you will lose any personal files you previously stored on the same partition as Windows. Repair installing – You can replace every corrupted Windows file with an in-place repair procedure while maintaining your personal files (including applications and games). However, this process is a bit lengthy.
