Vim-open file in existing window new tab on Windows

Opening files in VIM editor via context menu is quite simple, but what if I want to open a file in a new tab in existing window?
The solution is quite simple, at least on my Windows 7 machine, but I guess it shoshould work also on previous versions of Windows.
1. Open regedit
2. Find hkey_classes_root/*/Shell
3. Right click on "shell" folder and create a new key and call it, I. e. "Open in a new Vim tab"
4. Right click on currently created folder and create a new key called "command"
5. into default string value enter following code:
C:\apps\Vim\vim73\gvim.exe
--remote-tab-silent %1
Ofcource the path to your gvim executable must be valid.

[Custom_frame_center shadow = "on"]

[/Custom_frame_center]

6. check it

[Custom_frame_center shadow = "on"]

[/Custom_frame_center]
