How to open a Command Prompt on a folder you are browsing with Windows Explorer GUI in Windows 7 ?

Finding a certain file in your Windows file system, using the graphical user interface (or GUI) through Windows Explorer is much easier, right ? 

Then usually, for advanced users, if you require a Command Prompt window, at that spot, you need to open a command prompt (ie. CMD) and get there again ... but, our good reasoning tells us that MS must have a short-cut, right ?

Running CMD.exe from the "run command" is quick, but you sometimes find that you are required to slowly change your folder path from the default CMD window to a different location on your computer, or even in network shares.

But there is the "eastern egg", that MS likes to hide from us, that is a super fast trick that will enable you to quickly open a CMD window to a specific location from the GUI by adding a  "Open Command Prompt Here" to the Explorer context menu. That way all you have to do is to open Windows Explorer, find the required folder and right-click the selected folder.  The context menu appearing is the "Open Command Prompt Here" option.

In older Windows operating systems you had to manually add the "Open Command Prompt Here" to the Explorer context menu.

But Windows Vista and Seven adds this very useful shortcut to the DEFAULT installation inside Windows Explorer context menu, that is, in kind of a hidden matter, for most.  ;-)

1) Open a Windows Explorer windows, browse to the required folder. Windows Explorer usually has two sides, the left (the directory list) and the right (the content of the directory you are selecting)

2) Right-click that folder in the "right pane" of the Windows Explorer window. Note that you do NOT have the "Open Command Prompt Here" option.

3) Release the right-click and now, hold the SHIFT key, before you right-click the folder, and Behold!  And he appears !

ATENTION:
This context menu "add-on" in only available when you right-click on the folder in the right pane, and not in the left pane.  So usually I navigate back one step to be able to use the CMD where I what to go.

Motherboard Boots with Blank screen until Windows or Linux starts

I have a Geforce 7600 GS with two ports, VGA and DVI, on a Gigabyte 965P-DS3 rev3.3.





My monitor is a Samsung SyncMaster P2370 (2ms/50000:1/16:9/1080p/DVI)

Until recently I was using the DVI-VGA cable to connect the Monitor DVI to my Geforce VGA port.

But, I started to get into arduino/RPi/uC testing and having another monitor on my desk became a big problem, I started to run out of space.


HDMI Switch
So I though I could just buy a DVI to HDMI adapter for each end and use a HDMI cable to connect my Monitor to my Graphic card, as easy as that, in this way I could do some cable swapping and have my Raspberry Pi connected just as fast with a HDMI switch.
DVI-HDMI adapter


Well I started by getting the DVI-HDMI Adapters to give it a try.  So I disconnected the DVI-VGA cable, installed the adapters and connected the new HDMI cable.

When I turned on the system....
no screen...but what!

After booting the Windows/Linux screen showed up at the login.

What the heck!  No boot screen ?!?!  I can't really live without boot screen!

So I started to research the blogs, news groups, and other chats to check similar bugs!

I found many similar problems with Windows 7 and Nvidia, as well as patches, mess with the bios, tips to undo updates, and many more procedures.

After a few days, with no solution found, I sad to my self, what the heck, just install the HDMI switch (I used a double face tape to glue it the the back of my Monitor) and lets just test the original plan.....and, behold! the boot screen is back! Hooray!

How this is possible ?

After some study about signals and HDMI standards, I concluded that the problem is with signal polarity, since we use the same type of adapter for both the Monitor side and also for the graphic card port.  When the HDMI switch is in place, it corrects the balanced line polarities and that's it!

Conclusion: there should be a DVI-HDMI adapter for each side of the connection (which is not available, by what I know).  And building your own HDMI cable is not very simple, and quite difficult to get the parts and hardware tools.

The HDMI switch I bought is this one:

The short HDMI cable I used to connect the Monitor to the HDMI switch is this one:

http://www.amazon.com/gp/product/B00870ZHCQ/ref=oh_details_o08_s00_i00?ie=UTF8&psc=1

I used a additional short HDMI cable to leave it connected to the second port of the HDMI switch to connect my RPi or other systems as needed.

Cheers!

Thoughts:
MS/Nvidia/Gigabyte/others should pay us to solve their problems, and Amzn should help us too!
