Process Explorer is an excellent tool for anyone tracking down a system performance problem. In other words, you can use Handle to figure out which program has a file locked open.

One of the more frustrating experiences for an end user is the inability to save, move or rename a file because Windows claims that the file is in use. AccessChk is also useful for verifying system resources have received the proper level of security. The tool works for files, folders, registry keys, Windows services and global objects. The AccessChk utility helps you determine which permissions are in effect. We have all run into situations in which a seemingly simple repair or maintenance operation is halted by unexpected security restrictions.
