title: Bypassing WindowsApps folder protection other than ACLs
body: <p>I noticed today that on windows 10 
  some apps in the folder C:\ProgramFiles\WindowsApps... are protected in some way other than just the access permissions.</p>
  
  <p>When installing Microsoft.MicrosoftEmulator_1.1.39.0_x64__8wekyb3d8bbwe.msix or Microsoft.253890156C685_1.0.0.0_x64__8wekyb3d8bbwe.Msix
  as well as it seams other apps from the store</p>
  
  <p>the Folders for those created in under C:\ProgramFiles\WindowsApps\ have some additional write protection.</p>
  
  <p>While a cmd prompt started as TrustedInstaller can create and delete folders in the apps that come pre-installed in the folders fo these apps this fails with an access denied error.
  Taking Ownership of those folders and files as well as adding full access permission does not solve the issue.</p>
  
  <p>With a cmd prompt started as system it is at least possible to create or delete folders but for the existing folders created by the package installer its still not able to create a file within those.</p>
  
  <p>This protection remains in place even when the system partition in question is mounted by an other windows 10 system.</p>
  
  <p>The only way I found to gain full access to these files is to mount the partition in a windows 7 installation.</p>
  
  <p>So it seams to me that MSFT has added som additional layer or patronizing the administrators which needs to be understood and broken.</p>
  
  <p>Any ideas how to get around this issue?</p>
