Known issues with this security update

  • The Fix it solution checks whether if an application is running that is using NTVDM.exe. If an application that is using NTVDM is running, you will receive a message prompting you to close the application before you continue.
  • The Fix it solution does not check whether the Local Group Policy Editor (GPedit.msc) is running. If GPedit.msc is running, you will not receive a message prompting you to close GPedit.msc before you continue. If you run the Fix it solution while GPedit.msc is running, you may experience the following issues:


    • The GPedit.msc user interface may not reflect the DTVDM settings changes that are made by the Fix it solution until you close and then restart GPedit.msc.
    • If you run the Fix it solution while GPedit.msc UI is running, and then you make additional changes in GPedit.msc without restarting GPedit.msc, the additional changes could overwrite the changes that are made by the Fix it solution. Therefore, the changes that are made by the Fix it solution may not be applied.


    To avoid these issues, we recommend that you close GPedit.msc before you run the Fix it solution.
Note You can use the gpupdate /force command in the Fix it solution make sure that the registry is updated. On some computers, this command may cause the Fix-it solution to take more time to be completed.
