That hasn't been true since Windows 98/ME. Windows uses virtual addressing plus ASLR and DEP for process isolation/protection. See here:

ReadProcessMemory and WriteProcessMemory are APIs Windows exposes for using other processes memory. Even if a process changes the default DACL to block it, admin level access can bypass it.

You can use system APIs to get the memory space of another application in Windows as long as their run by the same user.

However iirc processes can opt out of this so only administrators can.

Can override those opts without admin as well.
