# Disable WinCC Runtime Scroll Bars in the Computer Properties
If WinCC Runtime keeps showing scroll bars even after the OS Project Editor layout and picture height are corrected, check the WinCC computer's Graphics Runtime settings. In classic WinCC, scroll bars are controlled by a window attribute in Computer Properties; they are not necessarily hidden just because a picture fits the selected resolution. The source-reported route is WinCC Explorer → Computer → computer name → Graphics Runtime, then clear the Scroll Bar option and save the settings.

Why matching the screen resolution may not remove the bars
The ticket reports that the OS Project Editor layout and picture height are already correct, but scroll bars reappear after loading. In classic WinCC, the Runtime window attributes include an explicit Scroll Bar setting. That setting controls whether the Runtime window shows scroll bars for moving the process picture; it is separate from choosing an OS display layout.
Disable the Runtime scroll bars
- Open the project in WinCC Explorer on the Engineering Station.
- Select Computer and open the properties of the computer configured for the affected Runtime.
- Open the Graphics Runtime tab.
- In Window Attributes, clear Scroll Bar (or the equivalent scroll-bar option in the installed release).
- Confirm the Computer Properties dialog with OK to save the setting.
- Activate/reload Runtime using the normal procedure for the project, then verify the affected process picture.
The exact labels can vary by WinCC version. Confirm that you edited the computer object used by the Runtime station, especially in a multi-computer OS project.
If scroll bars return after an OS load
Check whether the setting was changed on the correct computer object and whether a subsequent OS Project Editor or project update restored other computer-specific settings. Compare the saved Graphics Runtime properties before and after the load. The source does not specify the PCS 7/WinCC version or the type of load, so it does not establish which operation is overwriting the setting.
Picture sizing versus scroll-bar visibility
Correct screen resolution and process-picture dimensions can prevent clipping, but they do not necessarily control the separate visibility setting for scroll bars. If the bars are disabled and the picture is larger than the Runtime window, the oversized content may no longer be reachable by scrolling. Ensure the full required picture area remains visible or use the documented scaling/layout options for the deployed version.
Verification
After saving the Graphics Runtime setting and starting Runtime, inspect the intended OS station and confirm the scroll bars are absent. Verify the right and bottom edges of the picture remain accessible and that no important controls are clipped. Repeat on each computer object where the setting needs to be consistent.
Version applicability
The source does not state the WinCC or PCS 7 version. Siemens' WinCC documentation describes a Scroll Bar window attribute in Computer Properties → Graphics Runtime, but the exact interface and persistence behavior should be checked in the manual matching the installed version.
Limitations and Operational Precautions
Disabling scroll bars hides the navigation method for content larger than the display window; it does not resize the picture. Check the actual Runtime geometry and picture bounds before removing them from an operator station. Changes to computer properties should follow the project's normal review and OS-update process.
Engineer FAQ
Where is the scroll-bar option? In classic WinCC, open Computer Properties for the Runtime computer and inspect the Graphics Runtime tab's Window Attributes.
Will selecting the right OS Project Editor resolution hide scroll bars? Not necessarily. Scroll-bar visibility is a separate Runtime window setting.
Should I disable scroll bars if the picture is too large? Only after confirming the entire required picture is visible or using a supported scaling/layout approach; removing the bars can make oversized content inaccessible.
Why might the bars return after a load? The ticket does not identify the load operation. Check whether the correct computer object was edited and compare its saved Graphics Runtime attributes before/after the update.
Does this apply to every WinCC generation? No universal claim is made; use the Computer Properties procedure documented for the installed WinCC/PCS 7 release.
