@Rajesh GaireTHANK YOU! I did not come and look until today when this bugging me again. Absolutely ridiculous to have to do it that way but I believe I was able to disable it.
I first found the config.json file by searching on it and finding it an Evernote subfolder. I opened it in Notepad and immediately save a copy by appending old before the .json extension. Then I reopened the original not copied file and deleteted the "ForceUpdateAtStart" command, while watching for comma placement. I suppose changing true to false would have worked but didn't try it. I then just saved the file. I also made sure Evernote was closed while doing this. It seems to be working.
@EverNoteIf it doesn't work, or I don't have sufficient privileges on my work computer to change the file, THAT'S IT. I have paid for your program personally for use at work and privately, have previously recommended strongly to family and friends, but this is ridiculously stupid that the update has been enabled on startup with no user option to disable. I can't install everyday at work, I don't have privileges to do so. I would have to call the help desk to do that.
