SharePoint Solution deployment not working and Falling in the front end after installing the SP1 (SharePoint Service Pack 1)

This issue is also generate the following event log.

Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchServiceInstance

Reason: Requested registry access is not allowed.

Technical Support Details:
System.Security.SecurityException: Requested registry access is not allowed.
   at Microsoft.Office.Server.Search.Administration.SearchServiceInstance.Synchronize()
   at Microsoft.Office.Server.Administration.ApplicationServerJob.ProvisionLocalSharedServiceInstances(Boolean isAdministrationServiceJob)

these might be other reason also like not having correct permission to the application pool running user. But in my case i solved it by running the SharePoint Product Configuration Wizard.
