Disk Security settings from DiskSecurity.xml cannot be applied to NTFS Junction. It can be cause of access errors if junctions for some Plesk or Windows dirs/files were created.
- Create a junction for the directory C:\Windows\TEMP\
- Use Plesk reconfigurator for applying Disk Security settings
- Disk Security cannot be applied to the junction C:\Windows\TEMP\, and secirity settings might be misconfigured.
In that case the following error message is appeared in php_error.log:

Grant the access with all required permissions manually.
