At this point few are the users who do not know how to change permissions to folders in Windows, for that reason today we explain step by step the best way to take possession of system files to make changes, change permissions through the command line, create the option in the context menu of the mouse and how to change permissions in Windows 8.
However, you need to manage the permissions of a particular file or folder that contains him or several files.
The first thing to keep in mind is that the permissions that are used in Windows serve both to allow and to deny or limit any modification.
In some cases they allow to protect files or folders or the opposite, give you the necessary access to yourself in case the file to modify only has valid permissions for SYSTEM, in addition, this is a hypothetical user, which is nothing more than the operating system.
But how do you manage permissions in Windows?
If you’ve ever asked this question, you should know that all permissions can be created, modified, or removed manually on the Security tab in the Properties tab, which is displayed when you right-click on any folder or file.
There are even multiple options to effectively manage permissions in Windows, but this article will only address the basic options, most used and most required by users.
Which languages are used in the permissions
In this case it is important to familiarize yourself with the language that appears in these cards. Group or user names are the terms used to identify the entity to which the permissions are assigned.
In addition, only a few are shown depending on content, location, or file type, the top five in the list are the most common, the next two are used in installed and system program folders, and the last four are used in shared folders.
- SYSTEM (Windows)
- Your Name
- HomeUsers (Users)
- CREATOR OWNER TrustedInstaller (Windows, system files)
However, if you want to deny, assign, or remove permissions for files and folders, you must perform the following steps:
- Right-click the file or folder.
- Now click on Properties and then on the Security tab.
- Click the Edit button to open the Permissions window.
- If the required entity is not listed in the Group or user names box, add it.
- Now select the user or group and check the Allow or Deny box in the corresponding permission.
- The permissions that can be denied and granted are the following: total control, modify, read and execute, show the contents of the folder, read, write.
There are also other series of special permissions for users, called special permissions. So if you want to define, view, change or remove special permissions you must do the following steps:
After opening Properties and the Security tab, click the Advanced button and then Change Permissions.
In the Permissions window click on the name of the group or user and then choose Edit.
If you check the box “Replace all permissions of secondary objects with inheritable permissions of this object”, the action will be applied to all subfolders and files.
Special permissions can be as follows: full control, through folder/execute file, show folder/read data, read attributes, read extended attributes, create files/writes data, create folders/annex data, write attributes, write extended attributes, delete subfolders and files, delete, read permissions, change permissions, take possession.
Now, in order to obtain permissions for files owned by SYSTEM and trustedlnstaller to make certain modifications to system files, it is important to take possession of them and for that you must do the following:
- After opening Properties and the Security tab, click the Advanced button and then the Owner tab.
- Now click on Edit, select in the New Owner list the one you are interested in, if it does not appear add it.
- Then check the box “Replace owner of all sub-containers and objects” to make it effective for all sub-folders and files. For this it is necessary to be administrator of the equipment, in that case it is possible to take possession of any file of the same one.
Change permissions through the command line
It is now possible to change the permissions using the command line, for some this system may be more convenient and quicker, while for others it may be somewhat embarrassing.
But for that CALCS commands are used and the most recent ICALCS, however, in Windows 8 changing the permissions to a file or folder is somewhat different than in Windows 7 or XP.
This is because the ACL editor has been redesigned, it is simpler with fewer dialog boxes. So to get full control of a file or folder in Windows 8 you must follow the steps below:
- Right-click on the folder containing the file and open the Properties.
- On the Security tab use the “Advanced Options” button.
- At the top click on the “Change” link next to TrustedInstaller.
- In the dialog box that opens type your username and click “Check Names”. The name will be adjusted to the corresponding object name.
- Now press OK on both windows.
- Under Properties select the modified object name and click “Edit”. This will open the Permissions window where you can select the name and check the necessary boxes in the Allow column.
- In order to have all the permissions it is necessary to mark: “Total control”.
- Finally press OK and now you have all the permissions.
You must take into account that a very simple and practical method to change the permissions to folders and files, is creating in the contextual menu of the mouse a button that allows it.
For that it is necessary to create some keys in the Registry, this is something complicated to do manually for those who do not know the edition of the Registry, but it is also possible to download the necessary keys and add them to the Registry with only two clicks.
