Steps 6 through 8 of method 2 in the "Let me fix it myself" section back up the following registry key to the file Components.reg on your desktop:
- If the steps in the resolution do not fix your issue, you can use this backup to restore the registry key to its previous state. To restore the registry key, simply double-click the Components.reg file on your desktop, click Yes at the verification prompt, and then click OK at the confirmation dialog box.
- If the steps in the resolution fix your issue, you may delete the Components.reg file on your desktop.
These keys are written by the Windows Modules Installer service, TrustedInstaller.exe, when a package that requires restart is being installed.
- PendingXmlIdentifier This key is created the first time that a package that requires restart is installed and is deleted after operations have completed following initiation of the restart.
- NextQueueEntryIndex and AdvancedInstallersNeedResolving These keys are sometimes created after restart is initiated to maintain the state.
In some cases, problems such as power loss or registry corruption can put these values in an inconsistent state that can prevent a client of TrustedInstaller (like the Windows Features screen) from functioning properly.
Deleting these values has no known side effects. However, we strongly recommend that you back up these registry values before you delete them.
