<![CDATA[How run Opera always in private mode and always in 96 DPI resolution?]]>[Opera 27.0.1689.54]
[Windows 8.1 Update 64-bit]
[Control Panel\All Control Panel Items\Display\Change the size of all items = Medium (125%)]

I want to use Opera always in private mode, and I want to use Opera always with a resolution of 96 DPI. The solution I found for this, is to add two parameters to the shortcut to start Opera, like this:

"C:\Program Files (x86)\Opera\launcher.exe" --private --alt-high-dpi-setting=96

This solution is only a partial solution. When Opera is not running, and I double click on a file which is being opened by Opera -- then I do not get private mode, and I do not get a 96 DPI resolution.

Now my question is: How can I set Opera so that it will always run in private mode and in a 96 DPI resolution, without using start-up parameters? (I guess changes in the Windows Registry should be able to do this.)

I do not want to change my general PC configuration, because that will impact other programs than Opera. I do not want to discuss whether it is a good or bad idea to use the private mode or a 96 DPI resolution. I am just looking for a way to always run Opera in private mode and with a 96 DPI resolution, without using start-up parameters. Thank you.

When I will update Opera myself, or reinstall Opera -- I expect I will have to redo those registry changes.

If it suddenly goes back to as it was before, that will be why.

I think your solution is smart, because it still uses the start-up parameters (in a way I did not expect). I implemented your solution in this way:

In the Windows Registry, all occurences of

"C:\Program Files (x86)\Opera\Launcher.exe" -noautoupdate -- "%1"

have a key ending with "shell\open\command", so they are related to opening a file in Opera. I changed all these occurrences into

"C:\Program Files (x86)\Opera\Launcher.exe" -noautoupdate --private --alt-high-dpi-setting=96 -- "%1"

After these Registry changes, when I double click on a file which is being opened by Opera -- then I get private mode, and I get a 96 DPI resolution. So this is really the solution I was looking for. Thank you.

"C:\Program Files (x86)\Opera\launcher.exe" --private --alt-high-dpi-setting=96 -- "%1"
