Whilst doing some NPM build work for VSTS Extensions I kept getting intermittent EPERM errors about renaming Windows files during NPM install (as discussed on GitHub)l. When you get this it completely blocks any development.

As the Github issue discusses there are many possible reasons for this issue, and many proposed potential solutions. However the only one that worked for me was to restart VS Code; as this appeared to be locking the node_modules folder somehow. This was even though I could delete it via Windows Explorer without any problems.

A quick restart of VS Code and all was good again for a while, good enough to work with.
