Pagefile can potentially hold sensitive data. There is an option to wipe pagefile on shutdown, which takes long and probably does not work with SSD disks. And there is an option to encrypt the pagefile.
However according to this source: https://social.technet.microsoft.com/Forums/windows/en-US/fe44476d-a0f0-4e20-a6c5-c790c177a021/ntfs-pagefile-encryption?forum=w7itprosecurity the encryption key is always the same.
So my suggestion is to have an option to generate a new encryption key for the pagefile on every boot which makes previous versions of the pagefile inaccessible and there would be no need to wipe the pagefile on shutdown anymore.
