Latest Windows 10 updates break access to some UK Government websites
If you have installed the latest round of cumulative updates for Microsoft's Windows 10 operating system, you may have noticed that some official government sites in the UK are no longer accessible in Internet Explorer or Microsoft Edge.
Microsoft released security updates for all supported versions of Windows 10 on Tuesday on the company's monthly Patch Day. On Thursday, Microsoft added a known issue to the update KB4494441Â for Windows 10 version 1809 revealing that it may install twice on some user devices.
Update: Microsoft released updates for Windows 10 on May 19, 2019 that fix the issue described below. End
Today, another issue was added to the list of known issues; this time, for all updates for Windows 10 released on the May 2019 Patch Day.
After installing the May 14, 2019 update, some gov.uk websites that donâ€™t support HTTP Strict Transport Security (HSTS) may not be accessible through Internet Explorer 11 or Microsoft Edge.
The issue affects connectivity to some UK government websites (those ending in gov.uk). Microsoft notes that the issue affects sites that don't support HSTS (HTTP Strict Transport Security), and that the issue affects Internet Explorer and Microsoft Edge only.
One of the changes in the released updates added gov.uk to the HTTP Strict Transport Security Top Level Domains (HSTS TLD) for Internet Explorer and Microsoft Edge.
While that improves security when connecting to these sites, it breaks gov.uk sites that don't support HSTS.
Microsoft notes that it is working on a resolution for the issue and plans to release an update quickly to resolve the issue in all supported versions of the operating system.
Windows 10 users who run into the problem may want to use a different web browser to access these government sites in the meantime as the issue affects Internet Explorer 11 and Microsoft Edge only. If that is not possible and access to these sites is essential, it is only possible to uninstall the cumulative update to resolve the issue.
Affected versions of Windows 10 and Windows Server:
- Windows 10 version 1809 -- KB4494441
- Windows Server 2019 -- KB4494441
- Windows 10 version 1803 -- KB4499167
- Windows 10 version 1709 -- KB4499179
- Windows 10 version 1703 -- KB4499181
- Windows 10 version 1607 -- KB4494440
- Windows Server 2016 -- KB4494440
The number of broken UK government sites is unknown but it is important enough for Microsoft to add it to the list of known issues. The latest issue highlights again that Microsoft's approach to testing and verifying updates needs to be improved.
Did Microsoft generate a list of uk.gov websites and test connectivity to those in IE and Edge?
Microsoft Updates – SNAFU
It should be news IMO when a new Windows 10 update actually doesn’t break something. xD
Blocking the UK surveillance state? It seems to me like this might be a security feature.
Thing is, sometimes we have to use these pages as UK residents or citizens. Blocking whole page because it doesn’t support HSTS doesn’t solve a surveillance problem ðŸ˜Š

One good reason for not using the Edge browser
That’s Microsoft’s way of boosting America’s GDP : first break things, then repair them.
Boeing does the same … two crashes with about 600 casualties … now some new software … so sad. ðŸ˜’
Don’t drink and write !
Why not? Who cares? Those/these were only numbers on a sheet. Is anyone jailed,charged or even asked? no.
If you care, your only option is to boycott them.
The list could be endless.
Little reported is this KB also broke their porn filter.
MS breaks all!
That’s a “feature” not a bug.
Best comment in a long time.
Does anyone remember Patch Day which doesn’t break anything during Win 10 system?
Sure, there are people who love to repair something in Windows all the time, improve, etc. like me many years ago. But normal user no matter he/she uses computer for gaming or for work want to have working and stable system which is not breaked by creator of system specially if upgrades are obligatory.
But now it looks like a sad joke and neverending story.
Since WIndows 3.11 I have always changed the system a year after its new relase to avoid to be a beta tester. But now the life shows the solutions and management of the system is a huge mistake so no way to change the system from my Win 7 (and nixes).
I need my computer for work not for experiments.
Just my point of view ;)
This must be a blessing for the common British people. Finally a little bit of peace from this highly skilled and well organized government. ….would you like a cup of tea ?
Interesting. At least I can access, for example
using Windows 10 version 1903. So maybe it’s not effected?
At least this time, it’s M$ informing us of the issues by adding it to the official documentation.
It’s really quite stupid to force HSTS like this, even to hosts which resolve to RFC1918 addresses.
Lots of broken internal systems in gov.uk today as a result
That’s the only good bug I have heard about.
UK should fix their webpages, a government page without correctly working HSTS? What are we, in the 1980-s with security?
Not a big deal. Who on earth uses Internet Explorer 11 or Microsoft Edge ?
Right we all remember that Patch Day is sort of a joke, so no one should be surprised or disappointed because no one was dumb enough to let MS update their Windows computer(s).
Both times this has installed I have had to run a repair to get Office 2019 working. It did not affect Office 2016 on my Laptop.
As of 1530 utc, on 18 May, the KB4494441 hasn’t been pushed here. Yesterday the other 2 – flash and .net updates arrived. So, I wonder if they halted the KB4494441 temporarily.
Via WU about 3 hours ago I installed KB4505036 after deciding the warning notes at
https://support.microsoft.com/en-us/help/4505056/windows-10-update-kb4505056 did not apply to me. Microsoft Windows [Version 10.0.17763.504] works well for me.
Fixed in KB4505056: https://support.microsoft.com/en-in/help/4505056/windows-10-update-kb4505056
