Hi,

After installing version 10, Windows has started to systematically open the "Open File Security Warning" dialog whenever I tried to Edit in... Photoshop CC from LR. Which is rather annoying since the option allowing to permanently disable the warning for that executable no longer exists.

A solution for those who are hit by this issue...

It is possible to disable the security warning globally (Internet Options | Security | Internet | Custom level | Miscellaneous | Launching applications and unsafe files (enable) ). This works but Windows 10 will now start to systematically warn you that your system is at risk. Kind of a chicken/egg - hair pulling - chicken plucking problem. Microsoft are very good at inventing such things.

There's a better solution although it can be considered unsafe by some users.
  1. Launch REGEDIT or any other registry editor.
  2. Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Associations.
  3. If the string value LowRiskFileTypes for that key doesn't exist, create it.
  4. Set it to ".exe;.bat;.cmd;.vbs" without the quotes.
  5. Logoff and login again.
You'll no longer be bothered with these annoying and somehow useless warnings when trying to execute a program or a script downloaded from the Internet. I do not consider this as unsafe if you have a good antivirus software running on your system.

However, I think there's something wrong with the CC installer. I didn't have this issue when launching PS directly, only from LR.

Hope this helps.
 
Thanks for sharing Patrick.
