What GNU/Linux applications do you want to use? If you want desktop free software such as Firefox, LibreOffice, LMMS, Inkscape or Kdenlive, you can install many of them directly on Windows, it will run faster than a virtual machine. If you want to learn the command line, such as bash, curl, vim, imagemagick and ffmpeg, or program in C or C++ using the GNU toolchain, try WSL, from which you can access your Windows files under /mnt/c, /mnt/d etc. A standalone virtual machine makes sense when you want to play with a desktop environment such as KDE or GNOME, or a tiny compositor such as Sway, or a rare desktop app that isn't cross-platform. But it's more pleasant to run them on hardware directly, having installed Debian or Fedora on a USB SSD.
