Once every pending update is installed, restart your computer once again and see if you still see the 0x80D03805 error when trying to perform an action in Windows Store.

Clearing the cache of the Windows Store

In most cases, the problem will turn out to be caused by a selection of temp files that are stored inside the cache folder.

As it turns out, this type of problem will most likely appear after a security scanner quarantined some items belonging to the Store cache or after an unexpected machine interruption.

If this particular scenario is applicable, you should be able to resolve the issue by resetting the entire Windows Store cache.

Resetting the Windows Store cache via Windows PowerShell

1. Right Mouse Button click at the Start button;

2. Run Windows PowerShell (Admin)

3. Type the next command:

wsreset.exe

After the command is processed successfully, restart your computer and see if the problem is resolved at the next startup.

Resetting the Windows Store via Settings app

1. Press Windows key + R to open up a Run dialog box;

2. Next, type settings:appsfeatures and press Enter to open up the Apps & Features menu of the Settings app.

2. Navigate to Update&Security;

3. Scroll down through the list of installed applications until you see the Microsoft Store entry.

4. Click on the Advanced Option hyperlink (under Microsoft Corporation).

5. Scroll down to the Reset button and click it to initiate the process of clearing out the cache.

Wait until the process is complete, then reboot your machine and see if the issue is resolved at the next startup.
