In the process of using win7 system, I believe everyone has encountered the phenomenon of residual shadow when dragging the folder window or browser window. So how to solve the problem of residual shadow when dragging the window? Now listen to me for you.
1. Make sure that your system does not run too many software, resulting in system load failure! You can try to restart it;
2. Change the theme. This phenomenon may only occur under a certain theme;
3. Right click "computer" -- "properties" -- "advanced system settings" -- "performance settings" -- "visual effects" button, then uncheck "show shadow under window" in the setting and click OK;
3. If it still fails, update the graphics card driver;
4. If you can't do it again, try to reinstall it! Or change your graphics card! Everything must be OK!
To obtain administrator privileges:
① right click the folder or file to be deleted - properties - Security - Advanced - all.
② click Edit - continue - other users or groups, and enter the name of the selected object

Enter your current login user name (or click Advanced - find now, select your user name and confirm).
③ select "replace all sub containers and objects". If we don't select such a folder, we only have the full rights of such a folder and all the rights of its sub folders and files inside (if we delete a single file, this selection can be omitted), and then apply - OK. In this way, we have the full rights of such a folder, because the full rights of such a folder previously belonged to the system, not to us.
④ click permission - Edit - add, fill in your user name (or use advanced - find now and confirm), then click your user name - edit, check the "full control / allow" and confirm. ⑤ Then tick "replace the existing inheritable permissions on all descendants with the permissions that can be inherited from this object". If you don't check it, you only have the permission of the folder outside, and the folder inside still can't be "fully controlled". ⑥ After that, apply - OK - OK - OK.
