Replacer: Free Portable Utility to Replace System Files in Windows
NOTE: The article has been updated with a new software review. The previous software caused problems to some users. You can use this new software without any problem.
Most of the times when we want to customize Windows look, we need to replace existing Windows system files with new files which we download from various websites or we create after modifying default files.
To replace the existing system files, first we need to take ownership of the file using following tutorial:
Then we need to rename the file to some other name. After that we copy new file to the same folder and restart our system so that Windows can start using new customized file.
If you don't want to to the above mentioned steps, you can use a freeware "Replacer" to replace files automatically.
Just download Replacer, extract the ZIP file and run "Replacer.cmd" file present in the extracted folder. Now you need to drag-n-drop the default system file (which you want to replace) in Replacer's window. After that drag-n-drop the new modified file which will replace the default file. Replacer will ask for confirmation, press "Y" and you have done.
Restart your system and it'll replace the default file with new one upon next reboot.
PS: You can also type the complete file path in Replacer window instead of drag-n-drop the file.
Please note that, before replacing the file it will generate a backup of the original file. The backup is stored in the same folder as the system file, with the extension "backup" (such as "notepad.backup"). If there is an issue with replacing the file, for example, a system file is being used, it will ask if you would like to replace on next Windows boot.
As the file is being replaced, a log is written to "ReplacerUndo.txt" in the Windows folder. If the replacement prevents the system from properly booting, the previous operation can be reversed from the recovery console using BATCH ReplacerUndo.txt command.
