Remove Microsoft Bloatware ( OneDrive, Defender, Games, Ads, etc ) from Windows 10?

Update 2018: These break semi frequently as MS has been neutering Group Policies let me know in comments if something's broken or submit edits

As no program like that exists, here are the steps for everything you need. This will result in a quite clean Windows 10 Pro, without OneDrive, Defender, Candy Crush, Bing or annoying security warnings. The key is to master windows Group Policies. Some of these require windows Enterprise edition, but there are registry hacks that may achieve the same result.

You can remove the bar by right clicking it and selecting hidden.

Change default search engine on Edge Browser

1. Go to Google.com.
2. click on the browser settings

There are a number of tools that will remove some of the bloatware that is preinstalled on most Windows PC's, such as PC Decrapifier and alternatives.

Uninstalling OneDrive is a bit more complex, and may pose complications if you registered Windows using the on-line password option. You can remove OneDrive using the Command line.. First kill any active OneDrive process, then (for a 64-bit system), enter:

%SystemRoot%\SysWOW64\OneDriveSetup.exe /uninstall

Defender, however, should not be removed directly -- instead, install almost any anti-malware suite, such as Avast!, Kaspersky etc. This will disable Defender, get rid of MS warnings that your system is unprotected, and ensure that your are not leaving the system wide open to malware. See PC Mag for one set of AV reviews.
