Known issues in this security update

  • After you install this security update, some programs may not run. (For example, some video games may not run.) To work around this issue, you can temporarily turn on the service for the secdrv.sys driver by running certain commands, or by editing the registry. Note When you no longer require the service to be running, we recommend that you turn off the service again.
