I got this problem, yes in Windows 10.

Solution?

To disable indexing of contents for that folder (the one containing the package.json)!!

On Windows Shell (File Manager), follow this steps:

1. Right click on the folder with the error, choose 'Properties'
2. Click the 'Advanced...' button.
3. Uncheck the checkbox 'Allow files in this folder to have contents indexed in addition to file properties'.
4. Press 'OK'.
5. On the previous Properties dialog (visible again), press 'Apply'
6. Check radio button 'Apply changes to this folder, subfolder and files'.
7. Press 'OK'.
8. (can take a while)
9. Press 'OK' (to close properties dialog).
10. Works!

You don't have the permissions necessary to remove that file. Somehow you have caused npm/bower to do things that conflict with the default windows permission system.

It would probably be simplest to remove bower and npm and reinstall them, and then update your npm to the latest version following the instructions here https://github.com/npm/npm/wiki/Troubleshooting

For a quick fix that might help, try this in a CMD window (you may need to start it as Administrator):

 cd C:\users\path\temp
 cacls . /T /E /C /G Everyone:F

That grants Everyone Full Control over your temp directory, which is potentially a security risk. However, it should make it possible for npm and bower to clean up old files.

I recommend you try reinstalling node, npm, and bower.
