Useful sp2010 _layouts locations

So you have a broken WebPart on a page, how do you remove it?

Easy, simply add '?contents=1' to the URL as a querystring parameter.

e.g. http://contoso/default.aspx?contents=1

It will take you to the 'Maintenance: Web Part Page' from where you can remove the problematic WebPart(s).



Update (2013/02/07):

URL	Description
?contents=1	Open web part
_layouts/settings.aspx	Site Settings
_layouts/user.aspx	Manage users for site
_layouts/create.aspx	Page to create content. (useful if you have a Silverlight problem)
_layouts/AreaWelcomePage.aspx	Welcome page settings
_layout/addgallery.aspx	Direct link to Silverlight creation page.
_layouts/storman.aspx	Storage metrics for your SharePoint site
