Hello,

it's not really the installer that is writing to "PendingFileRenameOperations". The installer detects "locked" (in-use) files and as a result, Windows logs them for being renamed at the next reboot. But by default, there should be a "Restart" message at the end of the installation (if the installer replaced in-use files). If it is a silent installation, I would suggest to check the status of General Information -> Advanced Settings -> Reboot Message at Silent Install

BTW, using a .sb7 extension in SB10 is not a problem. All (upgraded) project files formats are fully backward compatible. The text at the top (created with 2680) is just a script comment.
