What's wrong is a cumulative update KB4565503, which increases the operating system version number to 19041.388 and brings significant security improvements to devices with Windows 10.
According to user reports, KB4565503 removes some of its applications Windows 10 after installing it, although it should be noted that this does not happen on all devices.
Users reporting problems claim that the following three applications are nowhere to be seen after installing this cumulative update:
- Microsoft Paint (classic version)
It is currently unclear why Cumulative Update KB4565503 deletes these applications in Windows 10, but the only way to resolve the issue is to reinstall the applications manually.
Uninstalling the update will not bring back the applications. What might help is restoring your computer to a previous state using a restore point.
But to avoid this process, it would be good to install these applications manually. You will only need a few minutes. Reinstalling applications is very easy, as long as you are logged in with an administrator account.
Follow the route:
Settings - Applications - Optional features - Add feature
In the list, just select the applications you want to reinstall and you are ready.
Microsoft has not yet recognized this problem and according to the official KB page, KB4565503 presents only one known issue related to Microsoft IME.
