“Open With” is a very useful item in right-click context menu in Windows. You can often use it to open unknown type of files or pick a different application to open certain known type of files. For example, if the default Windows Media Play is having difficulty playing MKV file, I can use Open With to open the file in VLC instead.
If for some reason it disappeared on you, here is a quick registry hack to get it back without going through any repairing or recovering processes.
Open Registry Editor (search Regedit from Start menu), navigate to
HKEY_ClASSES_ROOT\*\shellex\ContextMenuHandlers
Right-click ContextMenuHandlers, select New, and Key.
Name the key as “Open With“, and set the default value as
{09799AFB-AD67-11d1-ABCD-00C04FC30936}
Restart Windows Explorer or just simply reboot. And it’s all set.
Bonus tip
Here are some bonus tips for you if you are the Context Menu junkie like us. You can actually have another set of very useful new Context Menu items, Copy To and Move To.
Under the key ContextMenuHandlers, create a new key call Copy To with the default value as {C2FBB630-2971-11D1-A18C-00C04FD75D13}, and another new key Move To with the value as {C2FBB631-2971-11D1-A18C-00C04FD75D13}.
After restart Windows Explorer services, you will see these two new items showing up in the right-click Context Menu.
That’s about it. These registry hacks apply to Windows 7 and above, including Windows 10.
Win10: open with is only visible when selecting only one file. It there a way to ‘openwith’ multiple files?
