For some weird reasons my windows 8 started showing the context menu and cascades to the left side.

And after poking around a lot i figured it out.

 

To change context menu orientation :

 

1. Start the ‘Run’ command 2. Type in: shell:::{80F3F1D5-FECA-45F3-BC32-752C152E456E} – click on OK 3. This will start the Tablet PC Settings configuration dialog - even if you do not have a Tablet PC 4. Select the ‘Other’ tab 5. Under the ‘Handedness’ setting select: ‘Left-handed…’ – click on Apply and then Ok
