title: Inno Setup: uninsrestartdelete flag doesn't work sometimes
body: <p>My application installs some dynamic libraries in the {app} folder with uninsrestartdelete flag set upon installation. After uninstallation, these locked files are all written to the registry key PendingFileRenameOperations correctly. But on some Windows 10 machines, Windows just fails to delete these files and registry values on the next reboot. I have no idea what's going wrong. Even the OS itself doesn't have enough privileges to delete these files? Thanks!</p>
