Stop error 0x50 in the Win32k.sys driver after you install a font update

Applies To
Windows 7 Service Pack 1 Windows Server 2008 R2 Service Pack 1

Not sure if this is the right fix? We've added this issue to our memory dump diagnostic which can confirm.

Symptoms

You install a font update on a computer that's running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1). However, the system experiences Stop error 0x50 in the Win32k.sys driver. This error occurs when you do any of the following:

  • You restart the computer.
  • You start a program, such as an Office program.
  • You use Windows Explorer to browse to the font folder.

      

Cause

This problem occurs because the old font cache data was not cleared correctly. Therefore, the system incorrectly treats the font data as corrupted.

File information

The English (United States) version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.

Windows 7 and Windows Server 2008 R2 file information and notesImportant Windows 7 hotfixes and Windows Server 2008 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 7/Windows Server 2008 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, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    Version Product SR_Level Service branch
    6.1.760
    1.
    18xxx
    Windows 7 and Windows Server 2008 R2 SP1 GDR
    6.1.760
    1.
    22xxx
    Windows 7 and Windows Server 2008 R2 SP1 LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, extremely important issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • 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 7 and Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely 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.
