How to change the background of the window10 login screen

Win10 official version 1511 (10586,TH2) and subsequent versions have added the login background modification function, as shown in the figure below, after entering the "Settings lock screen", open "Show lock screen background on the login screen**" to modify. So, if you want to change the login background, just change the lock screen background.

Since win10 build 10159, Microsoft has taken the hero wallpaper as the default login screen of the system, but the radish and cabbage have their own loves, and it is inevitable that there will be aesthetic fatigue if you watch it more times, but unfortunately Microsoft does not provide the option to change the login background. So how to replace the default login background of Windows 10? Foreign netizen krutonium has found a way, let's do it with me.

First on the renderings:

To change the win10 login background screen, you need to replace a system file called the login background, which is in this file. Modifying the win10 login background screen requires two steps:

Note: A system update may cause the background to be reverted to default; In some cases, replacing the background may cause the update to be installed unsuccessfully or the system may be abnormal after the update, so it is recommended to restore the login screen to the default before updating the system.

1. Generate a file

**After unzipping to get the file, copy it to the desktop, and then prepare a copy of the one you want to replace** and put it on the desktop (support jpg, png format), assuming that this **name is note, the system does not display the file suffix by default).

Right-click the file, select "", and the system will automatically open with PowerShell ISE, as shown in the following image. We only need to modify the third line and change the file name to the ** file name that we have prepared. After good, save.

Right-click on the file, select "Run with PowerShell", at this time the PS run window will pop up, wait for a while after the window disappears, the file we want will be generated on the desktop, rename it.

2. Replace the file

First of all, install the Rubik's Cube (click here**) and open the "Setup Master" in the Rubik's Cube, as shown in the figure below. In the context menu - add context menu item, check "Administrator takes ownership" and click "Apply".

Then open the C: Windows SystemResources directory, right-click on the folder, and select "Administrator Takes Ownership". Wait for the cmd window to flash, and then we can work on the file in it.

Go to the directory and add it after the original file name. backup suffix for backup, and then copy the files you generated to it. During this period, if you are prompted to need permission, click "Continue". When completed, it is shown in the following image:

At this point, you can see the effect by locking the system or restarting it.

If you want to revert to the default, you can delete the generated file first, and then restore the name of the original file to the default.

In the future, Win10 Optimization Master and Rubik's Cube will add this function to facilitate one-click replacement.

After checking this option, if you want to change the login background, you only need to change the lock screen background.
