After Win7 sets the desktop background, the slide does not switch

After Win7 sets the desktop background, the slide does not switch. Of course, the premise is that your machine system version supports this function. If you have already set this function to be enabled and it is not available now, then we can check and solve it by checking whether the power plan is normal. The operation steps are as follows:
1, first enter "ld power supply option" in the start search box, press enter, open the power option, click “ change the plan settings & rdquo;;

2 In the Change Power Plan Settings, click “Change Advanced Power Settings 

3. In the Advanced Computer Settings dialog box, click “Change the currently unavailable settings 

4. After popping up the user account control window, please confirm or enter the account password with administrator rights;

5. Enter the advanced settings window, under the current power plan, expand “desktop background settings”- >“Show slideshow”, configure the settings to “available" state!
