After turning off the auto update feature in Skype, every time you are trying to log in (and immediately after you are logged in), this annoying box jumps out:
To get rid of the box, here’s what you should do:
Step 1: Start -> Type in “run” and hit enter
Step 2: Type in “services.msc” in the bar and click ok.
Step 3: Find “Skype Updater”, right click and select “Properties”
Step 4: In the new pop up box, change the Startup type from “Automatic” to “Disable”
Step 5: Double check that Skype Updater is now Disabled
Note: You might need to restart your computer to see the effect!!
