Windows 10: Failed update download due to 'insecure connection'

Binolio · Jan 1, 2022

I'm having a nightmare with my W10 upgrade purchased copy, not free download refusing to install my Cubase 11 updates due to InstallFiles.cab missing. I have finally tracked down the required file from the Microsoft Update catalogue: November 30, 2020—KB4586853 OS Builds 19041.662 and 19042.662. windows10.0-kb4586853-x64_9c181d397b4b5d320af7e6f385ebc4bba693a95c.msuHowever, when I try and download from this 'safe' source it refuses to download with a message saying it can't be downloaded securely.Words fail me.Any suggestions would be gratefully received! Thanks.

Google Protecting users from insecure downloads in Google Chrome

Today we’re announcing that Chrome will gradually ensure that secure (HTTPS) pages only download secure files. In a series of steps outlined below, we’ll start blocking "mixed content downloads" (non-HTTPS downloads started on secure pages). This move follows a plan we announced last year to start blocking all insecure subresources on secure pages.

Insecurely-downloaded files are a risk to users' security and privacy. For instance, insecurely-downloaded programs can be swapped out for malware by attackers, and eavesdroppers can read users' insecurely-downloaded bank statements. To address these risks, we plan to eventually remove support for insecure downloads in Chrome.

As a first step, we are focusing on insecure downloads started on secure pages. These cases are especially concerning because Chrome currently gives no indication to the user that their privacy and security are at risk.

Starting in Chrome 82 (to be released April 2020), Chrome will gradually start warning on, and later blocking, these mixed content downloads. File types that pose the most risk to users (e.g., executables) will be impacted first, with subsequent releases covering more file types. This gradual rollout is designed to mitigate the worst risks quickly, provide developers an opportunity to update sites, and minimize how many warnings Chrome users have to see.

We plan to roll out restrictions on mixed content downloads on desktop platforms (Windows, macOS, Chrome OS and Linux) first. Our plan for desktop platforms is as follows:

In Chrome 81 (released March 2020) and later:

Chrome will print a console message warning about all mixed content downloads.

In Chrome 82 (released April 2020):

Chrome will warn on mixed content downloads of executables (e.g. .exe).

In Chrome 83 (released June 2020):

Chrome will block mixed content executables.

Chrome will warn on mixed content archives (.zip) and disk images (.iso).

In Chrome 84 (released August 2020):

Chrome will block mixed content executables, archives and disk images.

Chrome will warn on all other mixed content downloads except image, audio, video and text formats.

In Chrome 85 (released September 2020):

Chrome will warn on mixed content downloads of images, audio, video, and text.

Chrome will block all other mixed content downloads.

In Chrome 86 (released October 2020) and beyond, Chrome will block all mixed content downloads.

Example of a potential warning

Chrome will delay the rollout for Android and iOS users by one release, starting warnings in Chrome 83. Mobile platforms have better native protection against malicious files, and this delay will give developers a head-start towards updating their sites before impacting mobile users.

Developers can prevent users from ever seeing a download warning by ensuring that downloads only use HTTPS. In the current version of Chrome Canary, or in Chrome 81 once released, developers can activate a warning on all mixed content downloads for testing by enabling the "Treat risky downloads over insecure connections as active mixed content" flag at chrome://flags/#treat-unsafe-downloads-as-active-content.

Enterprise and education customers can disable blocking on a per-site basis via the existing InsecureContentAllowedForUrls policy by adding a pattern matching the page requesting the download.

In the future, we expect to further restrict insecure downloads in Chrome. We encourage developers to fully migrate to HTTPS to avoid future restrictions and fully protect their users. Developers with questions are welcome to email us at L: [email protected].

I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
