Symptoms

You try to start a computer that is running Windows 7 or Windows Server 2008 R2. However, the operating system stops responding at the "Please wait" screen that appears before you are requested to press Ctrl+ALT+DEL. Therefore, you cannot log on to the computer. 

Cause

This issue occurs because an auto-start service remains in the pending mode for too long and cannot start during the Windows startup process. This is caused by a deadlock that occurs because of an interaction between Windows Error Reporting (WER) and AppLocker.

Windows 7 and Windows Server 2008 R2 file information notes


Important 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 MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
