Symptoms

Assume that you have a computer that is running Windows 8.1, Windows Server 2012 R2, Windows 8, Windows RT, or Windows Server 2012. If you are using an input method editor (IME) to enter text (for example, you enter Japanese or Korean text), and if the focus is changed repeatedly among some text box controls, the computer freezes. When this issue occurs, you have to restart the computer.

Note If you check the resources status in Windows Task Manager, you notice that the system is out of memory.

Cause

This issue occurs because a memory leak occurs in the Msctf.dll file. The memory leak causes the system to freeze.

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. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8.1/Windows Server 2012 R2" on the page. 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 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. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
