Question: Who’s more likely to make the right decision, uninstall 7-Zip completely or remove unused options from right-click context menu?

Some users may do not like to wait, cuz their system’s right-click menu takes too long to load completely; and Windows becomes even unresponsive. Well, initially I would not suggest you uninstall 7-Zip. Try performing the following actions to fix your Windows’ right-click menu:

  • Go to the 7-Zip folder on programs list, or just like the one below. Run 7-Zip File Manager in it.
  • 31

  • Click Tools and select Options… on the menu.
  • 32

  • Go to 7-Zip tab on the Option window. you can at least temporarily uncheck some unwanted items such as "Compress to <Archive>.7z/.zip and email", click Apply and OK.
  • 33

Still can’t uninstall 7-zip or modify your right-click menu? Or you constantly install and then uninstall programs on your Windows device? You’d better keep and run this lightweight yet no-nonsense uninstaller program because the standard/express uninstaller very often will leave messy traces all over your computer.
