It has been confirmed that the Windows 10 2018 update or the latest cumulative update for version 1809 comes with a newly confirmed error that may corrupt the operating system's language pack and may require a complete system reset if it cannot be recovered. According to official news released by Microsoft earlier this week, the issue only affects Asian language packs. The official KB page of the cumulative update affected indicates the following:
“ After installing KB4493509, devices with some Asian language packs installed may receive an error, '0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND. '”
Although Microsoft claims that the problem exists in the Windows 10 cumulative update KB4493509 released on April 9, the same error occurred in two other updates to Windows 10 version 1809, which was released in early May.
A complete list of cumulative updates for language pack failures is as follows:
April 9, 2019 - KB4493509 (OS Build 17763.437)
May 1, 2019 - KB4501835 (OS Build 17763.439)
May 3, 2019 - KB4495667 (OS Build 17763.475)
“Recommended full reset”
According to the solution suggested by Microsoft, users should try to uninstall and then reinstall the language pack on their device, as this can help prevent this problem. however,If this doesn't work, you should reset your PC completely. Microsoft claims it is undergoing a full fix and is committed to including updates in the upcoming release.
The next cumulative update for Windows 10 is expected to begin on May 14th when Microsoft's Patch Tuesday is launched.
Although the above suggestions can help solve the language pack problem, resetting the PC is definitely not the most convenient solution if it is only to solve the problem introduced by the cumulative update. If reinstalling the language pack does not fix the error, you should uninstall the cumulative update completely and wait for Microsoft to send the fix.
