问题
Update:
Based on down votes I got, I decided to explain why I am asking this question. I am writing a C# application that use the default printer.
The problem is when printing in Windows 10 through my application, the default printer is not returned as expected.
After some research, I found that it is a new feature developed by Microsoft: the last printer used for print is being the default one. However, that it is possible to turn this feature off.
Now, back to the original post:
I have Windows 10 installed and I am trying to turn off the "Let Windows manage my default printer" but I cannot find this option.
According to this answer, I tried to turn it off through regedit but the instance of LegacyDefaultPrinterMode is also not there.
Any idea why I cannot find turn off option? Is there any other alternative to turn this flag off?
