Microsoft Windows 10 KB4494441 could break some websites in the UK
Reason:
- Internet Explorer and Microsoft Edge are affected since they are not official anymore supported
- All other Browsers like Chrome/Chromium/Firefox/Opera etc are not affected!
Some gov.uk do not supporting HTTP Strict Transport Security (HSTS) which results in a website breakage.
Workaround:
Add "gov.uk" into the HSTS TLD in IE/Edge. A fix comes next patch day.
