I hate the invasive Dropbox client

Very hard to completely disable the Dropbox client, which sneaks its updater into every corner of my new Windows 10 system. Here’s what I had to do to finally get rid of it:

• On Dropbox client, Settings, uncheck start automatically;
• Disable “DbxSvc” and two “Dropbox Update Service” in services.msc;
• Disable startups at Task Manager > Startup tab;
• Disable services in Control Panel > Task Scheduler > Task Scheduler Library.

I want Dropbox client to update only when I run Dropbox. This invasive behavior is completely unnecessary.
