You can then right-click on your system files and take ownership of them. After that, you can rename all files and replace the system file / explorer.exe easily.
There are three methods, one for the beginners and the other for advanced users, click on the links below to start:
Method 1: Change registry path to explorer.exe
The easiest method to replace explorer.exe is to open the registry and then change the path to the explorer.exe.
0. Make sure to know the difference between a 64-bit explorer.exe and a 32-bit explorer.exe. You can’t use a 64-bit explorer.exe on a 32-bit system. Should you have no clue, please read this: What Windows Version do I have? 32 or 64?
1. Rename your new explorer.exe to explorer2.exe and copy it into the Windows directory: C:\Windows\
2. Open the registry: Click on “Start” and enter regedit into the search field:
3. Right-click on regedit at the top and select “Run as administrator”
4. Uncollapse the following path: HKEY_LOCAL_MACHINE>Software>Microsoft>Windows NT>CurrentVersion>Winlogon
5. Change explorer.exe to explorer2.exe.
6. End the process explorer.exe via the task manager and start a new process by entering “explorer2.exe”.
If 6. is too complicated for you: Reboot or read below for more instructions how to end the process explorer.exe.
Method 2: Take Ownership + Edit Permissions via Interface
Assign Ownership of Explorer.exe
1. Right-click on explorer.exe and click on “Properties“. Go to the tab “Security“, click on “Advanced“:
2. Go to the tab “Owner” and click on “Edit“:
3. Assign the ownership to your administrator account by selecting your “Administrator account” (usually Administrators(username\Administrators)) and click on “Apply“:
The current owner should now be your administrator account. Confirm that!
Change Permissions of Explorer.exe
4. Click on “OK” and you will be back at the security tab of explorer.exe. There click on “Edit”:
5. Select your administrator account (usually Administrators(username\Administrators ) and check the option “Full Control“. Click on “Apply“:
6. Now you can rename your explorer.exe to explorer.exe_old and copy your new explorer.exe into the Windows folder.
Restart your PC or restart explorer.exe (instructions below).
Method 3: Take Ownership via Command Prompt
Copy your new explorer.exe to C:\
Take Ownership of new Explorer.exe
Next, we take control of it!
You can either download this script: Download TakeOwnership.zip (it will add the option “take ownership to your context menu) or you can do it manually.
I usually do it manually:
Enter cmd.exe into the search field on the Start menu and right-click on cmd.exe, click on “Run as administrator”.
- Enter cd C:\Windows\
- Enter TAKEOWN /F explorer.exe
Open up the task manager (CTRL+ALT+DEL) and right-click on Explorer.exe and terminate it:
New Task (Run…)
Don’t be shocked, your taskbar will disappear. You can always make it reappear again by launching a new task and entering “explorer.exe”.
Now click on “New Task” and enter:
- runas /u:Administrator cmd.exe (this will launch cmd.exe as administrator)
You will be prompted for your password, enter it. If it does not work, read this tip:
Tip: If the command prompt immediately closes you did not enter an administrator password. First active the hidden administrator account of Windows 7 and then set a password for that account. Then you are able to open a command prompt via runas /u:Administrator cmd.exe.
If you receive the error: No mapping between account names and security ID’s was done please try another method of this tutorial or try running this after logging into the real admin account.
Take Ownership of old Explorer.exe
5. Take ownership of the real explorer.exe and grant permission to administrators to modify it :
- cd C:\Windows\
- TAKEOWN /F explorer.exe
- ICACLS explorer.exe /grant administrators:F
Final Step: Rename and move Explorer.exe
Rename the explorer.exe and paste the new explorer.exe into the Windows folder:
- Enter rename explorer.exe explorer.exe_old
- Enter move C:\explorer.exe C:\windows\
Back in the taskmanager click on “New Task” and enter “explorer.exe”. Voilà, you just replaced your explorer.exe!
Explorer.exe: Class not registered
If you receive the error “Class not registered”, you might want to try this:
Start > Run > regsvr32 ExplorerFrame.dll
Make sure that ExplorerFrame.dll is a valid DLL
If you receive the error “The module ExplorerFrame.dll was loaded but the entry-point DllRegisterServer was not found. Make sure that ExplorerFrame.dll is a valid DLL or OCX file and then try again”, you are probably trying to launch a 32-bit explorer.exe on a 64-bit system.
Are you running a 64-bit system? Then make sure that your new explorer.exe is a 64-bit file or it won’t work!
