Hi Kiet Tran98,
I am Dave, I will help you with this.
Close File Explorer.
1
Open the old Control Panel, not the new Settings App
At the top of Control Panel, set View to icons
Open Devices and Printers
Right click your PC and choose Properties
On the resulting dialog, select the Hardware tab
Find each of the simatic devices (there should be more than one), click Properties and delete the driver.
Then check if that folder is gone
2
If the folder is not gone
Open the Registry Editor
In the left pane, select 'Computer' at the top of the tree
Click Edit - Find
Search for simatic shell
For each key or entry found, right click and delete it
Then pressF3 to continue the search and repeat, deleting any found entry until you reach the end of the registry.
