Microsoft has released Windows updates during the weekend that address an issue that prevented access to unsecured GOV.UK Web sites with the help of Internet Explorer 11 and Microsoft Edge.
With the release of hotfix updates on Tuesday, May 2019, Microsoft added the GOV.UK top-level domain to its HTTP Strict Transport Security (HSTS) preload list. Internet Explorer and Microsoft Edge therefore only connect to GOV.UK sites using HTTPS.
It turned out that some GOV.UK sites did not support the HTTPS protocol. As a result, Microsoft Edge and Internet Explorer could no longer connect to it.
To solve this problem, Microsoft has released Windows updates over the weekend for Windows 7, Windows 8.1, and various versions of Windows 10, so that these sites can be viewed again.
"Fixes an issue that may prevent access to certain gov.uk websites that do not support HSTS (HTTP Strict Transport Security) security when using the Internet." Explorer 11 or Microsoft Edge. "
The Windows 7 and 8.1 update is KB4505050 and titled "Cumulative Update for Internet Explorer: May 18, 2019" and the Windows 10 version 1809 update is KB4505056 and "Update" cumulative for Windows 10 version 1809 ".
After you install these updates, you will need to restart your computer for the hotfix to take effect.
