Where are my documents and pictures?

[Pam49]

Installed Windows 10, thought it would integrate everything I already had on the pc. Since installing, cannot find any of my hundreds of documents and pictures. What do I do now?>
Also thought to uninstall, hoping to regain what I lost. Went to "Start", "Settings", "Update and Security", then "Recovery" as instructed. Was supposed to have a question; "Restore to Windows 7?" No question posted - I have Vista on this computer.
Frustrated and really upset that I have lost important and unrecoverable documents and pictures.

Check
C:\Users\YourUserName or OldUserName
C:\Windows.OLD same deal, users\username
See if you find anything in either of those two places before panicking too severely

Thanks, I hope it works. Also, Microsoft asking for my old password - have no idea since I never used it.
