CLI Installation fails when excecuting 'postininstall.js / postuninstall.js'

Comienza reproduciendo el fallo de instalación de la CLI de Windows y siguiendo la ruta que postinstall.js pasa a lib/common/services/cancellation.js y lib/common/file-system.js. Compara la ruta generada con la validación de mkdirp path-arg.js y verifica después que la instalación de npm se complete sin una ruta no válida en la configuración de Node y Windows indicada.

• CLI: 7.0.6
• Windows 10 x64
• Node 12.18.3 / Tried Current and 10.
• Npm v6.14.6 / Tried clearing cache and reinstalling everything including node.

I'm trying to install the cli but can't get a work around.

I tested it with debugger and seems to fail parsing something like 'C:\Users\prego\AppData\Local\Temp\C:\Users\prego\KillSwitches' which is the received path arg at /path-arg.js

And right after this evaluation

const badWinChars = /[*|"<>?:]/
    const {root} = parse(path)
    if (badWinChars.test(path.substr(root.length))

Logs this error in console.
(node:3216) [DEP0016] DeprecationWarning: 'root' is deprecated, use 'global'

I didn't find anything related to this, just one issue with a similar error but tried everything and it didn't work.
