Describe your issue

Whenever I run tailwindcss it creates 3 .node-files in the C:\Users\<username>\AppData\Local\Temp-folder. They don't get cleaned up and accumulate. As shown in this gif:

All three files are mostly binary data but contain "This program cannot be run in DOS mode." close to the start. Additionally, the smallest file contains:

<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel level='asInvoker' uiAccess='false' />
      </requestedPrivileges>
    </security>
  </trustInfo>
</assembly>

at the end, while the other two files contain something about some Rust crates in C:\Users\runneradmin\.cargo\registry\src\index.crates.io (there is no user runneradmin on my system).

Duplicate of #17114 (which was generally fixed)

These files are necessary to embed + run the native parts of our CLI (Oxide, Lightning CSS, and Parcel Watcher) on Windows and macOS (afaik, Linux can run them directly w/o writing to the filesystem first). Generally these get cleaned up after the program exits but on Windows I think the best that can be done here is cleaning them up after a reboot because of how it handles I/O and binaries loaded into a process.

If you reboot the files should disappear.
