Skype has an experimental feature that will allow you to search across your whole Skype chat history which is great because if you don’t remember who you talked to about something, then you are SOL.  It can take a bit of time depending on your chat history…mine is about 2 years old and large.

To enable the search follow the steps here: https://developer.skype.com/SkypeGarage/SkypeForWindowsExperimental#head-943f7a538d3e0b0fd66c09f77dcb21075990a78c

If you are not familiar with how to add registry files to windows do the following:

Start -> Run -> regedit

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Skype\Phone within the registry editor and then drag and drop the enabled registry file that you downloaded from the link above to the window.  This will pop up with a message saying that the registry value has been activated.

Once this is done shutdown Skype and then restart.

Under Chats there is a new link called Historic Chats.  This will allow you to search across all of your chats.

Very excited about this.
