Win 7 delete file prompt permission is not correct solution

Enter the topic, QQ has been used for a long time, always feels that the startup is very slow now, after clicking the QQ icon, it takes at least 5 seconds to see the login interface, so it is ready to uninstall with QQTM, but uninstall After I found out that there are a lot of QQ related files in the installation directory, I am going to completely delete it when I am ready to delete it. "You need XXX permissions...", so Google gave a comment about Win7 deleted files, the most talked about. Is the following method:

1. Select the file or folder you want to delete, right click on the folder --> Properties --> Switch to the "Security" tab --> ; click on the "Advanced" button at the bottom right --> Switch to the "Owners" tab --> click on the "Edit" button below --> In the "Change owner to" box, click on yourself The current user name, change the owner of the file to the current user name, such as Administrators, and check the "Replace sub-container and object owner" option (folder), all the way to determine, so You have ownership of the folder.

2. Go back to the "Security" option. In the "Group or User Name", except for the administrators, select the other three options to delete. Click OK to go all the way.

After the actual operation, I still can't delete it (the operation is definitely correct), the prompt is still there, and some sayings are to create a registry file according to the prompt, and there is a quick way to obtain administrator rights after importing. Then you can do anything, this way because you want to change the registry, did not dare to try, but read a lot of comments, this method seems to be possible; finally thought of the security mode, then enter the safe mode to delete the folder, very simple Normally deleted, and my heart was hijacked, so I went to the blog garden to make a record. If it is determined that the file or folder to be operated does not matter, and the system prompts that it cannot be operated, then entering safe mode is the best. Method.
