Windows 10: Changed permission to open windowsApps folder now none of the apps work and System restore...

I was trying to access the windowsapps folder and to do so I had to change the permissions. Once I had got into the folder I changed nothing, but now none of the apps from the Windows Store, or the Windows Store app itself, will open. Even the System restore doesn't work and returns the error 0x8007045b



I had changed the ownership from TrustedInstaller to Ishan and ran these commands


takeown /f WindowsApps /r

calcs WindowsApps /t /g everyone:f /c

How do I reset it back? I changed it back to TrustedInstaller but what about the commands

:)

 

Windows Store apps won't open after changing permissions on windowsapps folder

I was trying to access the windowsapps folder and to do so I had to change the permissions. Once I had got into the folder I changed nothing, but now none of the apps from the Windows Store, or the Windows Store app itself, will open. They simply display
the splash screen for a moment and close. I have tried running sfc /scannow multiple times, chkdsk /r, wsreset.exe and even refreshing windows. (which as I understood it should reset all the settings, but while all the permissions seem to have been reset the
apps still won't open.) Here are the current permissions for the windowsapps folder:

No Windows Apps working after changing permissions of "WindowsApp" folder

I wanted to see the contents and modify a file in one of the folders inside "C:\Program Files\WindowsApps". However, the default permissions set by windows doesn't allow me to do that, I changed it using Properties-> Security->Advanced. I was able to see
the contents but was thrown access denied dialog when trying to modify(copy/delete) any file.

The main problem is, after changing the permissions I noticed none of my apps that lives in WindowsApp folder is working, e.g: Calendar, Calculator, Office 365(Installed from Store). I have even tried setting the permissions back to "NT Service\TrusterInstaller"
but still not working.

Please provide instructions to resolve this problem.

 

Permission/Ownership Issues WindowsApps Folders...

I have been tearing what little hair I have left out of my head trying to copy a file from my desktop to the appropriate folder in the Kodi folder buried in the XBMC… folder in Windowsapps in a brand-new fairly high-end laptop running Windows 10 Pro. I cannot get beyond first what appears to be a UAC “Destination Folder Access Denied” error message saying “You’ll need to provide administrative permission to copy to this folder.” If I click on the UAC “continue” button I get another “Destination Folder Access Denied” error box saying “You need permission to perform this action.” The second error box has only “Try Again” and “Cancel” buttons. Nothing is listed under “More details” in either error box.

Here is most of what I have tried:

1. changing ownership of Windowsapps and all folders below it to my Microsoft account user and granting full-control permissions to Windowsapps and all folders below it;
2. changing ownership to administrators group for Windowsapps and all folders below it and granting full-control permissions to Windowsapps and all folders below it;
3. enabling the “hidden” administrator account, going back to my Microsoft user account and granting full-control rights to the administrator account, returning to the administrator account, taking control with that account, granting full control permission to Windowsapps and all folders below it;
4. creating a new administrator account and repeating 3;
5. completely disabling UAC through the registry, once in the default administrator account and once in my Microsoft account user.
6. adding and using the “Take Ownership” context option on a Windowsapps folder as described in the Tutorial at Add Take Ownership to Context Menu in Windows 10 ; and
7. running the following commands in an administrator command window:

In fact, even if I do an explicit copy from an administrator command window, I get an “access is denied” notice.

None of the many sources I have looked at online are of any help in dealing with this blockage. Please help — not only do I need to get full-control access to Windowsapps and its subfolders for this purpose, I also need to get full-control permission to Windowsapps folders in order to get rid of an annoying McAffee startup.exe which pops an error box on every boot up even though I removed McAffee in the normal way.

How can I get assured access to Windowsapps folders???
