Windows 7 desktop has an ad icon that can't be deleted

I often encounter pop-up advertisements or advertisements that imitate QQ notification messages in the lower right corner when I go online. What's more, some software will have rogue stubborn icons on the desktop after installation. Trojans and adware contained in those software can be killed (often some rogues will modify and delete themselves), but there will still be some residue on the desktop, those files are very special, right click does not delete the option, press "del" or "shift" +del" will not prompt for deletion.

What should I do?

In fact, in the XP era, you can use the "Desktop Cleanup Wizard", but this tool has not been used since the Vista era, so Vista and Windows7 systems can only use other methods.

Manually delete

Do it yourself, full of food and clothing, the following method:

Win key + R key to open the running window, then enter regedit, click OK to open the registry editor , find

HKEY_LOCAL_MacHINE/SOFTWARE/Microsoft Windows/CurrentVersion/Explorer/Desktop/NameSpace

Right click on the NameSpace, select "Export", save the REG file to the desktop first

In the above projects, each user is different, and several of them are included in the system, for example:

{450D8FBA-AD25-11D0-98A8-0800361B1103}

{645FF040-5081-101B-9F08-00AA002F954E}

............

The above two people please do not delete, and some can not be deleted, Because these items are different in each system, the next thing to do is to delete them.

Next, delete the items in the NameSpace one by one, and delete the name of each item before deleting one item. After deleting one item, refresh it on the desktop. If you delete the {3D3DBDD2- DD4D-B157-4264-0B0D4DD6BD45} item and the icons on the desktop are gone, edit the REG file you just exported with Notepad and delete the

HKEY_LOCAL_MacHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/Desktop/NameSpace/{3D3DBDD2-DD4D-B157-4264-0B0D4DD6BD45}]

@="xxxxxxxxxxxx"

More on the desktop If you can't delete the icon, you need to delete more than one. Then save it and finally import it into the registry, which will solve the problem.
