  • Inuse is primarily used to replace locked operating system files. After you run inuse, the specified file is not replaced until you restart the operating system. During restart, the operating system moves the file immediately after it runs AUTOCHK, but before it creates any paging files. This tool is useful for troubleshooting purposes, where you might need to replace an individual file on your computer instead of an entire set of files.


To replace an existing local file with an updated remote file, type:

inuse \\srvmain\windows\test.dll e:\windows\test.dll
