Symptoms

Assume that you create and encrypt a file by using Encrypting File System (EFS), and then you try to add a user's EFS certificate to the encrypted file and there are no EFS certificates in the certificate store. In this situation, when you open the properties of the encrypted file, the OK button is unavailable in the Add dialog box.

Note You can add the user to access the encrypted file by entering the Properties dialog box, clicking the General tab, clicking the Advanced tab, and then selecting the Add dialog box.

Windows 8.1 and Windows Server 2012 R2 file information and notes

Important Windows 8.1 hotfixes and Windows Server 2012 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems.

Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.3.960 0.17xxx

    Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2

    RTM

    GDR

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 8.1 and for Windows Server 2012 R2" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components.
