For users who are running Windows, the root update package will update the list of root certificates on your computer to the list that is accepted by Microsoft as part of the Microsoft Root Certificate Program. The file is updated periodically to add or remove root certificates or CAs from distribution by the Program. So if the missing certificates are not on your computer to begin with, then that Windows 7 Update package will not add any root certificates. It will just modify any that already exist and need modification?
Root certificates are updated on Windows Vista and later automatically. If it finds it, it downloads it to the system. To the user, the experience is seamless. The user does not see any security dialog boxes or warnings. The download happens automatically, behind the scenes. To install this update to resolve an issue which requires an update to the certificate revocation list. So you should not worry about it.
Juke, what you described in your reply is how it works for computers connected to the Internet. However, the subject of this thread is about computers with NO Internet access. There is software on these computers that needs to validate the digital signature of some executable files.
When the signatures are checked the error is "A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. To successfully complete the procedure in question, you will need to download a special utility called rootsupd - it is available at the following link.
A small window will appear asking you to overwrite the file - we don't need it, so select "No". Make sure all the arguments are correct, and then run the command by pressing I went into. If you continue to see failures, it means that one of the steps in step 2 was performed incorrectly and the procedure will need to be repeated. This updater expands on the existing automatic root update mechanism technology that is found in Windows Vista and in Windows 7 to let certificates that are compromised or are untrusted in some way be specifically flagged as untrusted.
A certificate trust list CTL is a predefined list of items that are signed by a trusted entity. All the items in the list are authenticated and approved by a trusted signing entity. This update expands on this existing functionality by adding known untrusted certificates to the untrusted certificate store by using a CTL that contains either their public key or their signature hash.
After this update is installed, customers benefit from quick automatic updates of untrusted certificates. Users who have disconnected systems will not benefit from this feature improvement.
These customers will still have to install the root certificate updates when they are made available. Please see the "More Information" section. This could cause problems for enterprises that hardcode these URLs in their firewalls as exceptions.
The following are the new URLs:. Users who have disconnected systems can install this update. But those users do not receive a benefit from the update. In fact, installing this update may cause service startup failures immediately after the server is restarted. Services that perform certificate validation tasks during service startup may experience an increased delay while network retrieval of the trusted and untrusted CTLs from Windows Update is tried.
This also results in a number of the WorkSpace App components not being deployed as the installation routine terminates prematurely. This issue may affect other drivers that are digitally signed. In the example above, the USB cat files supplied by Citrix are signed by the following certificate chain.
Although all appears normal and correct certs are present and trusted , the Citrix USB driver fails to install when the Microsoft certificates have been updated. Automatic Roots Certificate Update Configuration This of course can add additional time to web browsing and depending on WIndows Services, GPO configuration and connectivity may not be possible for a user to complete.
