Last week i got new hack to change the position for open with and winRAR context menu..
I just added single DWORD value in CLSID of open with n winRAR and it works perfect in a single try..
So i like it share with you..

Lets start..
follow my few steps and change your context menu position...

Settings:-

1] Start > Run > regedit> hit Enter
2] Registry > HKEY_CLASSES_ROOT > go to 'CLSID' key

for Open with..
3] CLSID > find & select {09799AFB-AD67-11d1-ABCD-00C04FC30936}
(to find press ctrl+F, look at only keys)
4] On right side pane you will see '(Default)' string value like 'Open With Context Menu Handler'
means your at right key
5] Right click in right side pane > add New > DWORD value
6] Name it as 'flags' > hit enter to save
7] Double click on flags to modify> set Hexadecimal value '1' (one)
8] Now refresh your desktop n check context menu

for WinRAR...
3] CLSID > find & select {B41DB860-8EE4-11D2-9906-E49FADC173CA}
4] Right click in right side pane > add New > DWORD value
6] Name it as 'flags' > hit enter to save
7] Double click on flags to modify> set Hexadecimal value '1' (one)

Remember:
1] if you set flags to '0' (zero) - Your selected context menu will be display under Rename menu
2] if you set flags to '1' (one) - Your selected context menu will be display with sendTo, copy to folder n move to folder (like in image)
3] if you set flags to '2' (two) - It display at default position
