data section setting PAGE_WRITECOPY

section '.data' data readable writeable

In WinDbg I see data segment is marked as PAGE_WRITECOPY.
Should it not be PAGE_READWRITE ?

I see that after writing data in that segment that it changes to PAGE_READWRITE and merges with the import section which is after it.

When launching a program made in Visual Studio there is no segment with PAGE_WRITECOPY.

From Windows documentation:

PAGE_READWRITE 0x04
Enables read-only or read/write access to the committed region of pages. If Data Execution Prevention is enabled, attempting to execute code in the committed region results in an access violation.

PAGE_WRITECOPY 0x08
Enables read-only or copy-on-write access to a mapped view of a file mapping object. An attempt to write to a committed copy-on-write page results in a private copy of the page being made for the process. The private page is marked as PAGE_READWRITE, and the change is written to the new page. If Data Execution Prevention is enabled, attempting to execute code in the committed region results in an access violation.
This flag is not supported by the VirtualAlloc or VirtualAllocEx functions.[/b]
