For example, when you create a folder called MyFolder, all subfolders and files created within MyFolder automatically inherit the permissions from that folder. Therefore, MyFolder has explicit permissions, while all subfolders and files within it have inherited permissions.
Effective permissions are based on a local evaluation of the user's group membership, user privileges, and permissions.
The Effective Permissions tab of the Advanced Security Settings property page lists the permissions that would be granted to the selected group or user based solely on the permissions granted directly through group membership. By resetting effective permissions, you will restore NTFS permissions of files and folders back to their default inherited permissions. Winaero greatly relies on your support.

Luckily, I can get into safe mode as an administrator, so I will try it. I deleted all the s entries in that registry, not knowing that it was important. I use the icacls command and it seems to work but after reboot the permissions are re-applied and the issue return. I will update the tool accordingly.
The follow link issue is really bad! If that is a YES, that is a great start…however there are now situations where an inheriting child had a desirable additional ACE over what it inherited…would you be able to capture that and then revisit the ACL and add again??? Hi, thanks for reaching out.
Honestly, I cannot properly answer this question for you. Thanks for this app!.. But im having problems with resetting file permissions of archive files like zip and iso.. Sorry for the mistake but it seems that its not just archive files thats having access denied, all kinds of file types were giving access denied.. Dont tell me that my files were corrupted because before i tried this app i ran some of that files thats and it ran without problems but after using this app I cant open my most important files anymore.
OK heres another update to my files.. It did gave me errors to some of my files after using this on my drive F, not folder, in the root of that drive theres this most important files that have had the probems occured and theres also somes folders with files in it, the files inside the folders dont have any errors, the only files thats having error are the ones located at the root of drive F.
I tried moving those files inside one of the folders then there it is! The problems are gone!. How is that? I happy that this little app fixed our permission problems hassle-free.. But why is my drive F acting like this now?.. Is drive F where Windows is installed? I updated the tool to warn before allowing users to change root folders from now on. I also added links to the utilities used. Any way to change individual files rather than whole folders?
I have a file in system32 I want to change, and I am afraid to mod the whole folder, eg. Regards, Dana. Okay a little clarification… Why exactly is resetting the file permissions on root bad? I thought the idea was to restore them to a factory like setting before like say a virus went rampant denying access to key folders. The Windows installer defines the needed file permissions of key folders at installation. If you reset NTFS file permissions of the root folder you are erasing all defined Windows protections and only the Windows Installer knows what permissions are needed and where.
The tool only knows the NTFS defaults. It knows nothing about what permissions Windows needs to operate safely. If you use the tool with the C: drive as target, even if Windows will be still working after that you are going to be hopelessly vulnerable to any and all malware.
INteresting point, there must be a default permission set that windows installer applies on new installs. Is it possible to get that by doing a permissions backup of a fresh install and then impress that on an old HD. Is this possible to get Windows to fuction? Out of curiosity I decided to use the free software TakeOwnershipPro to access two hidden folders — System Volume Information and Documents and Settings they now have the padlock symbol.
Is there a way of reversing what the software has done as I have no idea what the original settings were and I want to avoid using a recovery image if I can? Would my System Repair disc be of any use? Hi Paul.
I am not sure if the system recovery disk will repair the errors and leave the rest of your system intact. Hi brother, having read your article, and reading all the comments, I am very much anxious in doing this. My all the data is in this drive only.
I have tried your software. But nothing has happened. Please help. On running your software, a set of executions are happening no, so how we ll come to know that the program has run completely. Please help me brother. Take a permission backup first. If problem solved with one, repeat with others or all of them 3 The tool essentially will generate a bunch of commands that will be executed.
If you manually run those commands one by one. This is how you see if the program works. You will always get a message on the screen. Thanks for the instant reply brother. But if I try with one sub folder, how will I be able to know whether issue is solved or not.
Because the drive itself is not opening. I am trying again as per your comments. First without Taking ownership and then taking ownership. Have just one more query if you could help. After the program has run completely, do I have to restart the system before checking whether the issue is sloved or not? Good morning lallouslab, Just a headsup: I am getting an Antivirus warning, when downloading the ResetPermission.
I found that error while using the graphical tool. Thank you! I wonder why they keep flagging this simple executable it is not packed and it does not use suspicious APIs …hmm, maybe because it needs admin privilege as described in its manifest file. Gerbil, thanks again. As far as I know, the command line switches are case insensitive.
Can there be another indicator of processing to know when it is finished? Can the app allow usage across machines such that when you have a trashed HD and put it into another machine, you should be able to look at the users on the HD not the savior machine, and then match the corrupted permissions with the local users on that HD, or does this do this now.
It is not clear which users are being applied. Question, How does using this tool which BTW I am not sure is actually performing backups, I get nothing out of backup when the folder will still inherit permissions from its parent folder?
Does Reset also uncheck the inherit function? The program is open source, please feel free to look at all the links and references provided in the blog post itself. Most of what it does is documented. Claude, please read the blog post carefully. Question: Is it possible to use this tool to give a specific user permissions to the files and can you use it to set permissions on sub-folders when inheritance is turned off without turning it on. Eli, not as it is.
You can refer to the icacls command line utility documentation, then edit the proposed command from the ResetPermission. Any idea what I broke this time? Thanks for the report. That is weird. Hey man. Great utility. Very useful. Antivirus software has made my job and my life much more complicated and difficult than is necessary. I completely agree that even now, in , anti virus products are still absolute shit in detecting VALID malware and differentiating actual malware from other, valid applications.
Hi, Lallouslab! To cut to the chase, I recently denied Permissions to my Guest Account… not wanting to use it any further, and not wanting anyone else to use it! Access is denied. And further, if the problem stems from my wrongly reading the suffix of the object as the definitive description of what the object actually was! Nevertheless, the deed done, I began looking around the Net for a solution to the problem!
In fact! On one occasion, I waited two hours! I was hoping that Adham could remotely tweak my system… using my IP address! What would you suggest? I have to say I was very careful about downloading and opening your little program. But, it passed, and it worked!
Thank you so much! I would not trust to download something like that myself. Because of that, I was very transparent with my blog readers: I explain what the app does, I submitted the EXE to VirusTotal and most importantly, I provide the source code!!
Yes, I would be able. Please give me a week and I will update the tool. Thanks for the suggestion. Thanks so much for creating this tool. Just wonderful. Hi vigermam, there should be a pause. Thanks for your feedback.
Thank you so much I have music files and everyone had the sharing set to Nobody and all the file possessions screwed up. I sent you an email.
You are the second person who report this issue. I cannot reproduce on my machine so I will be waiting your email reply with more info and replies to my answers. Jasoy, please tell me what is the operating system version and what language you are using please! Really weird issue. If I send you a private copy with an attempted fix , would you be willing to test it out and tell me if it works? Although it is ticked by default, you may uncheck it if you intend to carry out other tasks.
If you are not the owner of the file, you may select this option to gain more control. If you check this option, the permissions for every file and folder inside the chosen directory will also be reset.
You can use it if following any links is unnecessary. Thereafter, the Windows command line will appear displaying the executed commands. You can press any key to quit the command line.
Your NTFS file permissions have been reset. This way, you can reset the NTFS file permissions directly by right-clicking the folder or file. This way, if your changes result into some errors, you can easily retrieve your backed up permissions.
Sounds nice? So, if any antivirus solution identifies it as a virus or Trojan, just ignore the false sense of security and continuing enjoying the use of this nifty little versatile utility.
