I love the long lead time between some proposals in the suggestion box and the actual answer. A lot longer than my blog queue (:
I Commenter Adam S wonders why holding the Ctrl key when selecting New Task from Task Manager will open a command prompt.Its a rogue feature.
I didn’t even know this was possible. It seems one of the fastest ways to start the console!

On Windows, the keyboard shortcut [WayBack] Windows-L will lock your workstation and when [WayBack] Fast User Switching is enabled – and when your (corporate) policies allow it – shows your Switch User screen.
First of all, there is [WayBack] TSDISCON (which I found thanks to [WayBack] this thread). It is meant to disconnect a terminal services session, but when you are logged in on the console, it just locks your workstation.
It is small (about 20 kilobyte) and [WayBack] has been there since Windows 2000.
Then there is the [WayBack] LockWorkStation function that does the same.
Lot’s of people think you can call LockWorkStation using rundll32.exe. As per Raymond Chen: [WayBack] (404) Don’t do that: it has a different parameter count and different calling convention than [Archive.is] rundll32.exe expects (note that in Raymond’s article, the last link is broken).
So now you all go upvote [WayBack] the TSDISCON answer and downvote the ruldll32.exe LockWorkStation answers on this [WayBack] SuperUser.com question.

PS: [WayBack] Rob van der Woude published a list of Terminal Server commands including TSDISCON.

You need to be administrator to see the output of the “net config server” command.
The inbound/outbound limit is 20:
Running ‘net config server’ at the command-line suggests that Windows 7 can support up to 20 inbound / 20 outbound incomplete connections.

A few tools to prevent your screensaver to run:
Note: on Windows 7 this will not prevent the inactivity timer on an RDP connection!

You can fix the “temporary profile” in Windows 7 if you have access to the registry.
So it totally depends on how tight security at your clients is, and how fast their alternative processes are…

The “route print” command in Windows will show you some “On-link” entries in the gateway column. This is from Windows Vista and up. Before that, you would see “127.0.0.1”.
While creating Windows Vista and Windows Server 2008, Microsoft built a “Next Generation TCP/IP Stack” (Wikipedia link) that – apart from adding IPv6 – added many new features and performance improvements.
Since traffic routable through the local machine can have multiple IPv4 and IPv6 addresses, it is not called ” 127.0.0.1″ any more, but “On-link” as the answers to the windows 7 – What does “On-link” mean on the result of “rout print” command? on SuperUser nicely point out:
They are addresses that can be resolved locally. They don’t need a gateway because they dont need to be routed.
Yep, the other three answers are correct: it’s just a route thats directly reachable the NIC is in direct contact with it; on the same subnet. To explain a little further though: by contrast, the routes that have a gateway IP listed must be contacted through that gateway.
Note that sometimes the new TCP/IP stack needs some arm wrestling in order to have it do what you want (for instance to have it honour TCP metrics).
Note that the “default gateway” line is also missing, as it is in the 0.0.0.0 network destination.
A few examples of what route print shows: Read the rest of this entry »

A few notes on TLIST.EXE:
This is what I downloaded as I prefer ISO files prefer web-installers:

Some clients generate their VPN connection settings using the CMAK (Connection Manager Administration Kit). Apart from the cumbersome way to support both x86 and x64 at the same time, they usually add in some kind of time-out feature, and often route the whole 10.0.0.0/8 network over the VPN to just host a couple of dozen machines. Having done most of my VPN connections by hand, and automating them using rasdial to dial these from the commandline, I also found out the hard way that you cannot use rasdial for CMAK generated VPN connections: it will give you the error “This function is not supported on this system.”. The funny thing is: you can disconnect using rasdial. Luckily, the far less well documented rasphonedoes work for dialing. The batch file below uses a few tricks, and you can set the parameters in the top of the batch file.

Thanks to Randy Glasbergen for the debt image
I love this quote from Jeff Attwood on technical debt in 2009:
periodically pay down your technical debt
and the Computer Weekely article about half a year ago:
Short-term speed may come at the price of long-term delays and cost.
Lately, I find that I need to explain Debt in relation to IT and Software Development more and more often.
We now all know what happens with the financial system when we let debt get out of control.
The same holds for your IT and Software Development.
Debts get introduced by not “playing by the rules”. The quotes are there because you can not always play nicely, and the rules are not always clear or known.
Lets give a few examples of rules that – from experience at clients – are more often than not neglected. The examples are based on Windows, but could just as easily be Mac OS X, Unix, OS/400 or anything else.
These few were examples ranged from technically very broad to specific. There are more, but these will give you a rough idea how wide the field of debt can be. Even debt outside the realm of Technical Debt can turn out to be really expensive.
Every time you postpone or skip a Windows version, you collect some debt in the hope (often wrongfully called expectation) that you earn more on the money/resource you just didn’t invest and putting that money/resource to use otherwise. The same holds for any other kind of debt.
The main problem with debt is not the total of the debt, it is the interest rate that makes the accrued debt grows faster than most people and organizations realize.
This is actually one of the main causes of the current world wide financial crisis, the same holds for many IT debts.
And for all kinds of debts, you often don’t know how high the interest rate will be, so the accrued value can be way beyond what you expect.
I’ve regularly seen projects collecting so much debt, that migration costs raised to thousands of hours because of it, resulting into management taking another very bad decision: rewriting the stuff from scratch. Don’t do that: Joel on Software excellently describes what happens when you do that.
What to do about it?
You might say “don’t collect debt”, but you can’t always avoid debt.
So you need to build periods where you pay off accrued debt. And you need to do that regularly, in order to avoid the interest pitfall.
This does not limit itself to software development (though that’s what I normally focus at). It covers a wide range of IT topics.
Sometimes, you can even pay your debt in advance. For instance, I was among the first to switch from Windows XP to the x64 of Windows Vista. I knew it would cause pain, but it immediately payed back by being able to use much more memory, and run more Virtual Machines at the same time. That made me more flexible and productive.

If you have RDP open on one or more of your computers, you should have patched your machines by now:
vulnerabilities in Microsoft’s implementation of the Remote Desktop Protocol (RDP) […] a Critical, remote code execution vulnerability affecting all versions of Windows. This blog post shares additional information with the following goals:
- To strongly encourage you to make a special priority of applying this particular update;
- To give you an option to harden your environment until the update can be applied.
