How to open developer console in salesforce without SOQL queries (I have to press x to close out like 12 SOQL queries when I open it)

I had to adjust a formula for one of my formula fields. However, I also have a field that is set to match the value of the formula field. The field is set via process builder.
 
After I updated the formula, the second field only updates after an update. (Edit => Save)
 
Is there any way I can perform this action (Edit => Save) on all Opportunities at once?

i need guidance regarding DataLoader any one please suggest to complete Challenge 8
