Windows 10 still uses a pagefile when it has to. However, now when your computer’s memory starts to fill up, Windows 10 will start compressing old pages of memory so they take up less space, similar to what happens when you create a ZIP archive of multiple files. So, for example, if you have an app running that you haven’t touched in a while, rather than copying the information about that app to pagefile, Windows will simply make it smaller, but keep it in memory. The trade off, of course, is that decompressing the compressed memory takes up more CPU cycles. Typically, however, this performance cost is much, much lower than it would be if the system had to retrieve data from a hard drive (even SSDs). So even with the compression, it’s faster to pull those old apps out of memory than it is to load them from the hard drive’s pagefile.
