Hmm, I would like to know what is happening with the data on the Linux swap partition when the Linux system is turned off and by the next start the Windows operating system via GRUB2 will start. 3 questionsWill Windows be able to access the data from the Linux swap partition if Linux is turned off the right way?Will Windows be able to access the data from the Linux swap partition if Linux is turned off the wrong way (hard reset)?The swap area contains the mirror of RAM at a given time right? So, it cannot be encrypted by default, right?
What is happening with the Linux swap partition data when running Windows via dual-boot

To questions 1 and 2: Yes, Windows is able to access the data from the swap partition. But is not able to interpret these data by default. So you could analyse the partition using some tools, but Windows would not display any data by default.To question 3:The swap partition (or file) does not contain a mirror of the RAM, it contains the data that didn't fit into the RAM any more and/or weren't accessed for a specific time.It can be encrypted be default, for example the *ubuntu system can encrypt their swap partitions using logical volumes.See also this tutorial as an example:Arch Linux  Swap encryption(Not really sure about it: Modern system should be able to encrypt their swap partitions and hibernate-to-disk.)
