Windows Explorer in Vista may sporadically display the message “Not Responding” during routine operation. This message is accompanied by a temporary freeze of Windows Explorer, or a complete lockup in which explorer automatically restarts or the explorer task must be ended using task manager (control+alt+delete).
Run the system file checker tool Click Start then click All Programs. Go to Accessories and right-click “Command Prompt” then click Run as administrator. Enter the command sfc /scannow and press return. After the scan and repairs are complete, restart.
Check your antivirus software The presence of multiple, conflicting antivirus or anti-spyware/malware programs can cause this issue.
Pick one and only one package and make sure it is updated frequently. Installation of multiple anti-virus packages can create conflicts that might actually weaken your system’s immunity and can create stability and performance issues.
Your antivirus software may also be out-of-date or incompatible with Vista. Here’s a list of some compatible programs–make sure you are using the latest of edition of whichever you choose.

- Go to User Accounts>Add User account>Create New “Admininstrator” Account
