Windows 7 desktop has an advertising icon can not be deleted how to do

Usually, when I go online, I often encounter pop-up advertisements or advertisements that imitate QQ notification messages in the lower right corner. 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 residuals on the desktop, those files are very special, right click does not delete the option, press “del” or &ldquo ;shift+del” will not prompt to delete.
What to 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 run 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 & rdquo;, save the REG file to the desktop first

In the above project, each user They are all 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 each item in the system is different, the following is to delete it.
Next, delete the items in the NameSpace one by one, and delete the name of each item before deleting one. 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"
If you can't delete multiple icons on the desktop, you need Delete multiple. Then save it and finally import it into the registry, which will solve the problem.
