Microsoft Windows Meltdown-Spectre patches


Earlier this week, Microsoft released a patch for Meltdown & Spectre security vulnerabilities.
As a safety measure, users with AV are not able to download the patch immediately until their vendors have confirmed compatibility with the latest security patch.

Our team has already conducted tests using SecureAPlus 4.7.7, and we found it to be compatible with the update.
To clarify, being unable to download the security patch is not a bug on SecureAPlus’s part. Having to set this is a temporary limitation inherent to the release of the patch by Microsoft.

To enable receiving the security patch update, please follow the steps:
1. Make sure that you are using the latest version of SecureAPlus. At the time of writing, this is SecureAPlus 4.7.7.
2. Download and run the following tool to enable the compatibility check in the product update:
3. Go to Settings > Update & security. Allow it to retrieve the update and install it.
4. After Windows downloads and finishes installing the update, you will need to reboot Windows. Depending on whether other critical updates were installed, you may not be prompted for a reboot - in this case, you would have to do so manually to implement the changes.
5. After rebooting, please check your update history and look for an entry containing the following string:
This entry indicates that you have successfully installed the Microsoft Windows Security Patch for the Meltdown and Spectre vulnerabilities.
Alternatively, your Windows version number should be at least 16299.192 or higher.

For Administrators who prefer to perform this manually, please follow the steps below:
1. Make sure SecureAPlus is already in 4.7.7
2. Set the following registry entry:
Value Name="cadca5fe-87d3-4b96-b7fb-a231484277cc"
3. Download and install KB4056892 from:

In future releases of SecureAPlus, this security update will automatically be available.

All of these patches need the enable compatibility to be set as mentioned in the previous thread. You can set it either by using the provided tool, or set the registry entry.
