Windows Se7en File Replacer is a simple application designed to backup the old file, try to “take ownership” and replace it with the new dragged or manually selected file.

System modders need to take ownership of a system file before it can be replaced. To make this process a little less time consuming I wrote a small program that does these tasks for you. This program will, backup the OLD file, save the ownerships, take Admin Ownerships and replace it with the NEW dragged or manually selected system file to finally restore the ownerships back to how they were found. It does this in just a few seconds!

Normally when a file is replaced the file's ownerships are changed and the "TrustedInstallers" will be gone. However, the Se7en File Replacer will save all file permissions of the file before replacing it and after replacement restores them back to how the Replacer found them!!
(even TrustedInstallers if the file had them to begin with)

The Replacer will first look in the "system32" folder for a match with your NEW dragged file, if the OLD file is found it will be backed up and replaced without prompt, otherwise you will be asked to select it manually in a file open dialog box.

(note for x64 users: please don't drag SysWOW64 files as they will be placed in the system32 folder, use the manual function instead!) The manual option will let the user select a new file first and then select the old file which needs to be replaced. With this function any file in any location can be replaced.

The option to restore the "TrustedInstaller" ownership of a system file. Please only use this on a file if you know it originally had the "Trusted Installer" permissions.

It's just an .exe and nothing will be installed.

WARNING: Use is at your own risk! This tool is to replace un-owned system files. Be careful not to use this if you don't know what you are doing. This can and will break the system if corrupted system files are used to be replaced!
