When combined with Ctrl or Alt: RDP Shift Key Gets Stuck (via:

Posted by jpluimers on 2014/08/01

When using Windows RDP you have the risk of a Shift key getting stuck.

This happens when press Ctrl and Shift. Make sure you release Shift first, otherwise Shift gets stuck.

Same with Alt and Shift: you have to release the Shift key first.

This is not a problem when using the OS X Remote Desktop application 8.x from Microsoft: only the Windows MSTSC.exe applications included in Windows 7 and higher suffer from this when you connect to Windows 7 and higher (including connecting from Windows to Windows Server and from Windows Server to Windows).

It does not happen with the MSTSC.exe in Windows 2000/XP and Windows Server 2003/2003 R2.


Here are the important results:

  • Press Shift and Control (either order) -> Release Shift -> Release Control: Normal state
  • Press Shift and Control (either order) -> Release Control -> Release Shift: Problem state 


RDP has a bug whereby the shift state incorrectly remains in the “pressed” state if, after pressing Shift+Control, the Control key is released first.

Bug reference

Bug is with Microsoft:

And the comments there:

You have described the exact same problem that I am having, only in my case it’s with RDP between two Win7 machines. […]

I have been using RDP for years without problems, until about 2 or 3 weeks ago when it suddenly starting going wrong.

Too bad the connect issue requires logon: I have no idea if this is ever going to be fixed.

Edit: some comments on G+

made in Delphi :)
Happens to me sometimes when connecting from Win7 to XP+.
Seems closely related in older OSs.
Frequently beaten by “Securing remote connection…” delay

Multiple office versions on one computer: it is possible, but you should not do it

Posted by jpluimers on 2014/08/01

Wow, I didn’t even know this was possible, but I recently came across a few people that had actually done this: run multiple versions of Office on one computer.

Microsoft even has a couple of knowledge base articles on it and indicate it is not recommended (wow!), installation/update orders, and potential issues you will face.

I’ve added the respective office version ranges for each link:
