I removed Windows Essentials, including Live Mail as the only component that I had from the pack, following the announcement from Microsoft that it will stop further support for the Essentials from 2017.

I then deployed Office Outlook 2010 as my main mail client.

Now I see in folder C:\Users\XXXX\AppData\Local\Microsoft there are a few subfolders presumably related to Windows Essentials:

Windows Live

Windows Live Mail

Windows Live Movie Maker

Windows Live Photo Gallery

Windows Mail 

WLSetup

The total size of above folders is almost 200 Mb.

Can I remove them safely?
