There are instances when a Windows system file must be replaced. This job, however, is not nearly as easy as it might seem. You cannot simply copy and paste a system file, because ownership and permissions must remain intact. This is meant to be a security measure for the Windows 7 operating system. However, because this measure was put in place, replacing system files can be a challenge.

Fortunately there are tools that can aid you with this job, including Windows Se7en File Replacer 1.5.4. This handy tool can be placed on a portable drive and used on any Windows 7 machine quickly and reliably.

Naturally, like most administrators, you will be hesitant to use such a tool. You want to make sure copying over system files doesn’t render your machine unbootable. So let’s take a look and see if Se7en File Replacer makes for a good solution.


  • Product: Windows Se7en File Replacer 1.5.4
  • Program written by: Fixit
  • Cost: Free
  • Supported systems: Windows XP, Vista, 7, and latest Server releases – 32 bit only (64 bit works, but not the drag and drop feature).

Who’s it for?

Obviously the act of replacing system files isn’t for every user. Certainly only system administrators would be undertaking such a task and those same administrators are the perfect target for such a tool. Why? Because no one wants to undertake the time involved with resetting permissions and ownership for system files when a tool exists to enable the drag and drop of such files. So the long and short of it all is that ANY administrator of a Windows machine, who might at any point need to replace a system file should have this tool.

What problem does it solve?

If you’ve ever tried to copy system files in Windows you know that the task is a challenge. Because of security issues (understandably so) both permissions and ownership HAVE TO remain intact. As this is not nearly as easy as it sounds, having a tool to handle this task quickly is a definite MUST have for administrators of Windows machines. And with the ability to drag and drop the files into a single interface, the problem is solved as efficiently as possible.

Standout features

  • Drag and drop
  • Tool copies original file (along with permissions and ownership) before copying is done
  • Automatically searches for the correct location of file to be copied
  • Undo
  • Refresh icon cache
  • Restore trusted installers
  • Launch system file check tool with scannow and scanfile parameters
  • Portable
  • Free

What’s wrong?

If there is something wrong with this tool it’s that it enables any user to get around an intentional security layer (permissions and ownership of system files) that could do harmful damage to a system should a corrupt file be used. Because of this, you will want to make sure this tool does not get into the wrong hands.

The moral of this story is – if you do not know what you are doing, you should NOT be using this tool.

Finally, if I may pick a nit here, although the interface is incredibly easy to use, it’s a bit outdated. This tool is a designed for administrators only and should reflect as such. But that is a seriously trivial issue as the tool works very well.
