Win7 requires SYSTEM permissions to solve file changes

Win7 requires SYSTEM permissions to change files. 1. You can directly delete files in safe mode. 2. You can also perform the following steps in normal mode to obtain the permission and then delete it: ① click the folder you want to obtain the permission, right-click it, and choose Properties ", let's first obtain the ownership of this folder, click "security"-"advanced"-"owner ". Click "edit"-"advanced"-"other users or groups", enter your username in the selected object name, or click "advanced"-"Search now, select your username, click OK, and then select "Replace sub-container and object owner". If this is not selected, we only have ownership of this folder, there is no ownership of his sub-folder and the files in it, and then "application"-"OK", so that we have ownership of this folder. ② Click "permission"-"edit"-"add" to enter your username or use "advanced"-"Search now" to confirm, click your user name-"edit", tick "Full Control"/"allow", and confirm, replace the existing inherited permissions on all future generations with the permissions that can be inherited from this object. If you do not check the previous permissions, you only have the permissions for the folder outside, the folder still cannot be "completely controlled", and then click "application"-"OK ". In this case, what do you want to do with this folder!
