Комментарии

BackgroundСвойство применяется только к состоянию RESTful элемента управления. The Background property applies only to the resting state of a control. Стиль по умолчанию элемента управления определяет его внешний вид при изменении состояния элемента управления. The default style of the control specifies its appearance when the state of the control changes. Например, если задать Background свойство для Button , кнопка будет иметь это значение только в том случае, если она не нажата или отключена. For example, if you set the Background property on a Button, the button has that value only when it is not pressed or disabled. Если требуется создать элемент управления с более сложной настройкой фона, необходимо определить стиль элемента управления. If you want to create a control that has a more advanced customization of the background, you must define the control’s style.

Это свойство влияет только на элемент управления, шаблон которого использует Background свойство в качестве параметра. This property only affects a control whose template uses the Background property as a parameter. В других элементах управления это свойство не оказывает влияния. On other controls, this property has no impact.

Most of us enjoy displaying our favorite Desktop Background or Wallpaper on our Windows Desktop. But, if you find for some reason that you cannot change the desktop background or wallpaper in Windows 10 or Windows 10/8/7, you may try some of these troubleshooting steps.

Cannot change Wallpaper in Windows 10

Before you begin, please check if you have installed and third-party customization software and if it is restricting you from changing the desktop background. If so uninstall it and restart your Windows PC. Here are a few other things that you need to check:

1. Check Accessibility setting
2. Check Power Options
3. Reset wallpaper cache
4. Check Registry setting
5. Check Group Policy.

1] Check Accessibility setting

Open Control Panel and select the ‘Ease of Access’ Center. Then, click on ‘Optimize Visual display’ link. Scroll down until you find ‘Make the computer easier to see’ section. Once found, make sure that Remove background images (where available) is unchecked. Save, Apply, Exit.

This should help!

2] Check Power Options

Open your Power Setting in Control Panel. Open Power Options > Select your power plan > Change plan settings > Change advanced power settings > Expand the Desktop background settings option > Expand Slide show.

Ensure that the Plugged in option is set to Available.

3] Reset wallpaper cache

If the above option too fails, maybe your TranscodedWallpaper.jpg file has become corrupted.

Open explorer and type the following in the address bar and hit Enter:

Here, rename TranscodedWallpaper.jpg to TranscodedWallpaper.old.

Next, double-click slideshow.ini file and open it with Notepad. Empty its contents. That is, select all the text and delete it. Save the changes. Close explorer windows.

4] Check Registry setting

If not, try this. Run regedit and navigate to the following key in the Registry Editor:

Right-click on Policies > New > KEY > name it as ActiveDesktop.

Next in the right side, right-click > New > DWORD > name it as NoChangingWallPaper.

The DWORD value 1 will restrict change in desktop wallpaper. To allow change give it value as 0.

5] Check Group Policy

Alternatively, you could open the Group Policy Editor, by typing gpedit.msc in Run box and hitting Enter.

Navigate to User Configuration > Administrative Templates > Desktop. Click Desktop again. Double-click Desktop Wallpaper.

Ensure that the Not Configured option is selected. This will enable the option to change the desktop background.

Update HKCU\Control Panel\Colors Background via CMD and apply immediately?

Hello all and thanks in advance for any assistance!

Every time I restart my PC at work, the group policy goes into effect and changes the background color of my system to the company default. In Windows 7, because the color of the background is a lighter color, it makes all icon text dark and impossible to read with my dark wallpaper. Also, if I remote into my machine and disable UI options for a smoother experience, the background is the very bright default color rather than a wallpaper. All that said, essentially I resort to changing the background color to a darker color manually by navigating to the «Window Color and Appearance» window and setting the Desktop color to a dark color.

So, I began looking for a way to automate this change, and my first thought is to create a simple BAT script and launch it from my Startup folder. I’ve figured out how to update the register entry for this particular color change, but I can’t seem to figure out how to make it take effect in the same way that selecting the «Apply» button in the «Window Color and Appearance» window forces the change.

Here is the Register change via CMD:

• REG ADD «HKEY_CURRENT_USER\Control Panel\Colors» /v Background /t REG_SZ /d «0 0 0» /f

That command appears to change the Registry value as intended. But, it never updates my actual desktop. Any thoughts on how to get it to apply the Registry change?

Here are a couple commands I’ve already tried, and they don’t seem to do the trick:

• RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters
• RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters 1, True

I’ve also tried stopping and restarting the Desktop Window Manager Session Manager, but the color change is still not applied:

• NET STOP uxsms
• NET START uxsms

I apologize for the long winded question. Any assistance is greatly appreciated!
