I thought this would be quite a nice feature to share with you all.
You need to download Power Commands for Visual Studio 2010. It is free.
What’s this all about?
You might already know this, if not this is about re opening the closed documents.
There are two ways to this.
If you close one or many opened documents within VS, you can re open the last closed document by navigating to Edit -> Undo Close. Alternatively you can use Ctrl + Shift + Z
2. Undo Closed Window.
You can also see your last closed documents in “Undo Close Window”. You can open this window by just navigating to View -> Other Windows – > Undo Closed Windows
