Get rid of hardcoded Windows installation path

```
/mnt/c/Windows/System32/
```

drive c is not only possible drive to install Winodws, and `Windows` is not only possible name for installation folder. also path to tools can change between windows versions

as far as I know tools from this folder can be called without full path. if not, we should detect the correct path (using env maybe) instead of using hardcoded value.
