Microsoft recently released a new Windows 10 cumulative updates to fix a bug affecting uk.gov websites. Update KB4505057 bumps the existing version of Windows 10 to 18362.116.

KB4505057 changelog

Gov.uk access issue fixed

This Windows 10 cumulative update fixed the issue that was restricting Microsoft Edge and Internet Explorer 11 browsers from accessing gov.uk websites.

The issue was caused by the May 2019 Patch Tuesday Updates that forced Microsoft Edge and Internet Explorer to use HTTPS to connect to gov.uk sites.

However, the company later confirmed that the browsers could no longer connect to some gov.uk websites.

Installation failure bug fix

This release also addresses another bug that was introduced with the previous builds. This bug was restricting new installations on the operating system with the error 0x800f081f – CBS_E_SOURCE_MISSING.

Speaking of which, if you get this error code again, you can use this troubleshooting guide to fix it.
