If you change the "Language used in menus and dialogs", the character set may not be 
changed automatically in all cases. We therefore recommend that you go to Control Panel and 
select the "Windows Classic" style under "Display", "Display Properties", "Appearance".
Note
PCS 7 only supports the main languages (primary language) of the operating system 
languages, for example English (US), but not English (GB).
Windows Authenticode Signature verification 
The change of the Windows Authenticode signature verification described in Microsoft Security 
Advisory 2915720 cannot be activated in PCS 7.
Asian version of PCS 7
The "SIMATIC PCS 7 Vx.x Asia" USB hardlock is required for each PC to operate the OS 
stations.
Bundle PCs
The product bundle PCs of PCS 7 are supplied with a multilingual operating system.
The default language is English; the multilingual packages which include German, French, 
Italian and Spanish are installed.
If you install a PC yourself, we recommend the following when selecting the operating system 
language:
● If the PC users only use one language, select the operating system language used for 
configuration/process control.
● If the users use multiple languages on the PC, select a multilingual operating system 
(English/USA by default) and then install the additional Multilingual User Interface Packs.
5.3.2 Partitioning hard disks
Partitioning the hard disks             
If you are not using a preconfigured PC from a PCS 7 product bundle, but instead a different 
type, divide the PC's hard disk into the following partitions to facilitate easy data backup.
● For the operating system and the PCS 7 installation: Minimum 100 GB, see example
● For PCS 7 project data: At least 100 GB, possibly several partitions
● For backups: Back up the projects and archives to media that will not be affected by a failure 
of the PC or the hard disk with the original data, for example, a DVD or on the network.
If you use a preconfigured PC from a product bundle, the configuration-specific partitions are 
set up.
