VSP1CLN Command-Line Options

The Windows Vista Service Pack 1 (SP1) Files Removal Tool (VSP1CLN.exe) can be used to remove the files that are archived after Windows Vista SP1 is applied. Running this tool is optional.

Installing Windows Vista SP1 increases the amount of disk space that is used by the operating system. This space is used to archive files so that SP1 can be uninstalled. Typically, you should run VSP1CLN.exe if you want to reclaim this disk space after applying SP1 and if you will not need to uninstall SP1.

Important
You cannot uninstall Windows Vista SP1 after you run this tool on an image.

This tool works in conjunction with SP1 only and can be used online or offline.

VSP1CLN.exe Command-Line Options

The following command-line options are available for the Vista SP1 RTM Files Removal Tool:

VSP1CLN.exe [/h] | [/o: Offline_Windows_directory_path] [/quiet]

These command-line options are not case sensitive.

Option	Description
/? or /h	Displays this list of VSP1CLN commands.
/o:[Offline_Windows_directory_path]	Indicates that the archived RTM files that need to be removed are in an offline image.
/quiet	Runs in quiet mode. No console output is provided. If this option is not used, you will be prompted with a confirmation message.
/verbose	Provides additional diagnostics output.

Important
Upon completion, you will not be able to remove Windows Vista SP1 from the image.

Firstly, check the size of the folder (Windows\winsxs) by right-clicking it, choose Properties and make a note of its size and the number of files and folders. To run the program, open Windows Explorer and navigate to C:\Windows\System32, look for the file VSP1CLN.EXE (the capitals are for clarity only), right-click it, select Run As Administrator then reply Y to the prompt.

Now check its size again to see how much disk space you have reclaimed, you will be surprised as it will be quite substantial.

There is no harm in running the program where SP1 was either included on the DVD or slipstreamed into the DVD before installation. Depending upon what has been installed, you may gain some disk space.
