Error 0x800706D9: I cannot update Apps


Hello,

I have clean installed the latest Windows 10 Pro, 64 bit, build 14393.10

After the clean installation I have uninstalled the Apps I do not need by using commands in PowerShell, from a tutorial from this site. For a couple of newly added Apps I used CCleaner Pro to uninstall them. I have left the Store and the Calculator, only.

Now, when I check for updates in the Store, there is an update for Calculator but I keep getting this:



I use the Windows Firewall, and not a 3rd party firewall or antivirus, and it is running fine. I have also scanned my system with SFC and DISM and no integrity violations or corruption were found.

Are you getting this error? Can you update your Apps?
What can I do, besides a clean installation again?

Thank you.

Hi, app updates run ok post anniversary upgrade for me.
See here:

Similarly there's a discussion on the err. message here, alas with some unpleasant language.

It's almost not worth uninstalling the default apps - each major upgrade will replace them, as will an in-place upgrade repair install if run. The overhead isn't noticeable.

If I wanted to install an app I'd installed I'd prefer to rt click it on the start menu, and click uninstall, for example.

Thank you for your reply.

I have clean installed the OS again, and this time I uninstalled all the unwanted Apps by right-clicking and selecting "Uninstall", and for those I could not uninstall this way, I used CCleaner Pro. It seems that now it works. I post the following screenshot, showing the remaining Apps updating properly this time.



I assume my mistake was that I have uninstalled the newly added "Store Purchase App". After leaving it installed, my Apps now update normally from the Store, or at least the seem to do so. I have also left "App Installer" just in case...

I am glad that in this new Anniversary Update my system keeps functioning (perfectly), the way it has been always doing.

Thank you.

Good.. if you find the Store missing (as I did recently for no accountable reason along with Photos) you can reinstall it with a Powershell command.


Also be aware of
a. disk imaging - which you should use routinely so you can restore your PC to a previously working state relatively painlessly- also provides a complete backup. Macrium Reflect (free) + external disk + its boot medium
b. in-place upgrade repair install (see Tutorial section).

These usually mean you don't have to clean install and reinstall all 3rd party programs and redo settings etc etc etc

Hello Joanne,

If you haven't already, you might see if clearing and resetting the Store cache may help.

I've tried it, and also re-registering the Apps, but it doesn't work. Last question: do you happen to know which Service, if there's any, might affect the build-in Apps? Like preventing them from updating?

Thank you.

PS: the only build-in Application I have kept is the Calculator. If it will continue giving me problems, like refusing to update, I will just install Windows 7 calculator, and be done with it.

Worse case, you can do a repair install to fix it without losing anything.

Thanks Brink

It is too much to do a Repair install just because the Calculator fails to update. I might just install Win 7 calculator if the problem insists. And, by the way, in my system (see System Specs), I need 15 - 18 minutes to clean-install the OS and all the required drivers. So, it's not a big deal for me. It would be nice to know the cause of this, but it's OK. No problem.


I wouldn't do it just for that one app, but only if you have this issue updating all apps.

If you haven't already, you might see resetting and re-registering the Calculator app may help.

Thanks Brink, tried both, it does not work...

By the way:




Thanks a lot, anyway
