Keys in the CNG user interface are always described as having no description in Windows 7 or in Windows Server 2008 R2

Applies to: Windows 7 EnterpriseWindows 7 Home BasicWindows 7 Home Premium

Symptoms


The description of keys in the Crypto Next Generation (CNG) user interface always includes the following information, even when a description of the key is provided:
There is no key description provided with this key.
Note In the Crypto Next Generation (CNG) user interface, the information that is included in several dialog boxes includes the key description. The key description is useful to users who manage multiple keys. For example, when you have to sign an email message by using a key from multiple available keys, the key description is useful for determining which key should be used.

Resolution


After you install the hotfix, you can read existing key descriptions by using the CNG user interface. However, you cannot edit key descriptions by using the CNG user interface.
