Reset all user permissions to default in Windows 8.1?
Win8.1 Permissions problem
I need help globally changing the drive C: directory security settings, write protection attributes, possibly "Ownership", back to Windows 7 equivalents, so that the security restrictions appearing during the install of Win8.1 stop restricting my use of the directories normally accessed.
This is a home-machine with me having sole-access, so I'm not concerned about "internal" security (Internet Security is provided by MicroSoft Defender, kept fully updated).
PC with Win7 had problems (probably HDD drivers corrupted through several weeks of BSoD) to the point where it would no longer boot to any disk, repair, restore didn't help.
Purchased and Installed Windows 8.1 on top.
Install of Win8.1 appeared to be successful.
Windows Upgrade DLed and installed upgrades OK.
Install of Office 2003 and it's upgrades appeared OK
Install of several other programs appeared OK
HOWEVER, I tried re-installing other programs I had previously used, (versions I had successfully installed on my Wni7 machine of: Quicken, Adobe Acrobat, Photoshop). These installs appeared to fail due to blocked install paths or insufficient permissions to install to those paths.
I examined many of the data directories, My Document dirs, Program File dirs, ProgramData dirs, and all appear to have their WriteProtection attribute set. When I try to change that attribute, IE appears to take the change, but re-inspection of the dir shows no change.
Some directories, I can add or delete entries, even though they indicate as Write Protected.
FYI: MY SETTINGS:______________________
Logged in under my Microsoft Account - Administrator level
File Manager / select drive C:\, RightClick and select Properties, select tab_Security
(All Group or User names show their Permissions to be Full Control)
Advanced Security Settings for C:
Owner = SYSTEM
tab_Permissions: (all entries show Full Control)
Everyone = Full Control
ALL APPLICATION PACKAGES
SYSTEM = Full Control
Administrators ("my account name"\Administrator)
Users ("my account name"\Users)
Examples of who owns various important directories:, FYI:
Owned by SYSTEM:
owned by "MyAccountName"
C:\Users\"MyAccountName"\ (all subdirs)
owned by TrustedInstaller
Fixes that use Rollbacks, System State backups, or Undo won't help me as it's a new install of Win8.1
I've seen several Answers, mostly relating to Vista or Win7, that don't seem to apply.
I tried using the Subinacl Tool but it won't install (due to insufficient permissions!), and it's documentation doesn't make it clear it's for Win8+ anyway.
If I don't get a fix pretty soon, I'm gong to pull out my old Win7 disk and do a virgin install of it, and have to spend another couple of weeks re-installing and configuring all my old software. Please help!!!

You could try Windows Repair (All in one) http://www.tweaking.com/content/page...ll_in_one.html
It advises you do the pre-checks and back ups before running the program in a clean boot and if you still have problems, register and open a thread on the forum and Shane (the author) will probably be able to resolve for you.

If you installed Win 8.1 as an upgrade to an already corrupted Win 7 os that is most likely your problem.
Try a clean install and let it format your drive.
I wouldn't bother making an image of your corrupted Win 7 install. If you decide to go back to Win 7 your best bet is to do a clean install of that os.
Rich5000 years ago, Moses said 2 Israel, "Pick up your shovels, mount your asses & camels, & I will lead you 2 the Promised Land." When Welfare was introduced, Roosevelt said, "Lay down your shovels, sit on your asses, & light up a Camel, this is the Promised Land." Now the government has stolen your shovel, taxed your asses, raised the price of Camels & mortgaged the Promised Land to China

Actually, since 8.1 refused to transfer / import any of the installed programs and settings from the previous Win7, I should have sprung for an all-new HDD, and put 8.1 on it, and then copied over what files and settings I could, manually.
