Windows 7: Taking 'ownership' questions.

Taking 'ownership' questions.

I've been told by my Trend Micro Antivirus tech to 'take ownership' of my 'C' drive, but it's been over a week, and I can't get a response to my question.

When I right click my 'C' drive, go to 'properties', then 'security', then 'Advanced', then 'owner', then 'Edit', there's two options in the 'Change owner to' box..

Tod(Tod-PC\Tod) and Administrators(Tod-PC\Administrators).

What is the difference between
between these two?

I normally sign on with my standard user account 'Tod'(not an administrator account).

Which account should I click in the 'Change owner to' box?

Thanks!

I recommend not taking ownership of Partition 'C'.

No. If you take ownership of the Windows C: drive, it will cause Windows to become unstable. You'll most likely end up having to reinstall Windows if you do.

You have to be logged in as an administrator to take ownership. if you are being presented with "Tod" as an option to take ownership then "Tod" is an administrator account, It's likely to be a tokenized admin account but is still a very powerful account, and should be used with care.

As for the Trend Micro "Tech" I would suggest that he gets a job that he is qualified to do. Bad programming on behalf of the developer can give a need to take ownership of their own application folder(s), but never the whole system drive.

Take ownership is an emergency tool to get a problem solved until it can be correctly set-up - all changes that are suggested to be made using take ownership should instead be corrected by the correct use of NTFS permissions system.

You also need to be aware that the ownership of files and folders is the baseline level for all the security that is built into a modern era Windows OS, every time a user Takes Ownership of a file or number of files or folder, in the system, then the overall security of the system is eroded, the more that is changed the more the system security is weakened.

Although we are unaware of the actual issue that has led you to the Tech mentioned, I will state that any problem that requires the complete ownership of the system drive to be changed to correct. is likely to beyond saving as a secure system. I would advise that you save your personal data to an external device and reinstall Windows.

take ownership

Hi Everyone, I use Trend Micro Internet Security, and purchase it from the technicians who built my pc,

and I have never heard anyone say anything about taking ownership of C drive. Trend seems to work fine

without doing anything to change the system, just my two cents worth.

Hi,
The only time I might take ownership of C partition would be if the hdd it was on was hosed already and I wanted assess to personal files on it to transfer off of it after clean installing windows already
TrendMicro product have a nasty past of causing all types of issues requiring people to reinstall windows
But feel free to follow the advice

Taking 'Ownership' questions

Thanks everyone for responding...yikes! looks like I won't be taking ownership of my 'C' drive...sounds very dangerous.

The Trend tech wanted me to take ownership because, about a month ago the Trend scans would 'hang', and just 'freeze'. I let it run for hours, and even overnight, it was still frozen.

The Trend tech and I went back and forth for a month, either on the phone, or via email, trying various things to resolve this. About a week ago, he wanted me to run CHKDSK C:/f/r.

I did that via CMD prompt(elevated), and got this msg::Cannot lock current drive. Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N).

Then he wanted me to change permissions to 'Everyone' Full control for CREATOR OWNER, SYSTEM, Administrators(Tod-PC\Administrators), Users(Tod-PC\Users), and TrustedInstaller.

The only group that has full control is 'SYSTEM'(there is no Creator Owner, or TrustedInstaller). When I first checked this(last week), when I clicked the 'Edit' button, and the 'Permissions for Local Disk (C' box came up, the 'Add' button was greyed out, and all the boxes in the 'Permissions for Authenticated Users' were un-clickable. But, trying it today, the 'Add' button is hi-lighted. Should I click the 'Full control' boxes for the Authenticated Users, Administrators(Tod-PC\Administrators), and Users(Tod-PC\Users) groups? Should I add an 'Everyone', and/or a 'Creator Owner' group and give them full control?

Whew, all so confusing!

Thanks!

Everyone and TrustedInstaller are both system generated and have special purposes Everyone has a low rank, very little basic access rights, but contains every user on a system both user generated and system generated, giving everyone full control is almost as bad as taking ownership of the system drive.

Trusted Installer is part of the Windows Virtualized security system It is system generated and Owns all the folders and files in the program files (and Program Files (x86)), folders this user is positioned above even the Administrators Group members and only the Full Hidden Administrator has a higher rank.

Creator Owner is another system generated user that is only used basically as a placeholder to give some special control to the generator of certain files.

Changing the rights of any of these users is likely to completely mess up the carefully designed security and rights that are an essential to the stable running of the system

What I would be tempted to do is to uninstall Trend Micro, preferably using a removal tool on their site, and then running the Admin level CHKDSK C:/f/r. again. it may also be a benefit to run the system file checker to ensure that the system is correctly setup.

after this it should be fine to re-install Trend Micro and hopefully this will run correctly again

Thanks for quick response. Since today is Sunday, I'll wait through Tuesday for Trend to respond. If no response, then I will try what you suggested. Thanks!

taking ownership

Hi tkmops I uncheck the box in Trend settings for PC health checkup, as it says it is optimising the pc,

and as I am unsure what it actually does, I leave it unchecked, the machine is running fine on its own.

Taking 'Ownership' questions

I just got a response from the Trend tech, he says to:'Please change the ownership for your drives to Administrators(Tod-PC\Administrators). After changing the ownership,please do the CHKDSK [Drive Letter]: /f /r and afterwards a scan on your drives.'

From what I've read in the prior posts, changing ownership is not a good idea, neither is doing CHKDSK [Drive Letter]: /f /r.

Thoughts, anyone?
Thanks!
