Send Ctrl-Alt-Delete in a remote desktop session

Remote Desktop is a nifty little windows feature that allows you to remotely connect to another PC and manage it as if you were physically at the console. You can read my previous post on how to setup remote desktop in Windows XP.

When connecting to another machine, just about all keyboard actions are transmitted to the remote machine, i.e. pressing Enter, typing, pressing the Windows key, etc. However, that is not the case for some key combinations.

ctrl alt del remote desktop

One that has bothered me for a very long time when using Remote Desktop in Windows is when I press Ctrl + Alt + Del while logged into the remote computer. Instead of sending the key combo to the remote computer, it would instead perform the action on my computer!

This was actually intended by Microsoft because there are many cases where you may not want that to be sent to the remote computer. So, by default, Ctrl + Alt + Del will only work for the local computer.

So how does one perform this same action on the remote computer? It’s pretty easy actually! In order to send Ctrl + Alt + Del to the remote PC, just press the following alternate key combination:

Ctrl + Alt + End

That’s it! Pretty easy eh? Unfortunately, I tend to use Remote Desktop rarely and therefore forget this key combo all the time! Also, note that there are a bunch of other keyboard shortcuts you can use in Remote Desktop:

Alt + Page Up – Switch between programs (Alt + Tab is the local command)

Ctrl + Alt + End – Display the Task Manager (Ctrl + Shift + Esc is the local command)

Alt + Home – Brings up the Start menu on the remote computer

Ctrl + Alt + (+) Plus/ (-) Minus – Minus takes a snapshot of the active window and plus takes a snapshot of the entire remote desktop window.

Those are pretty much all of the remote desktop keyboard shortcuts you will ever need! If you know of anymore, post a comment! Enjoy!

How to turn off DEP (Data Execution Prevention) in Windows

Data Execution Prevention, otherwise known as DEP, is a set of technologies incorporated into Windows XP SP2 and later that prevents code from being run in certain regions of memory that are for storage.

This helps to prevent all kinds of attacks and exploits that would normally be able to run freely on your system. Data Execution Prevention comes in two flavors, hardware-enforced DEP and software-enforced DEP.

Most users will never need to worry about DEP because it works in the background and normally only protects Windows system binaries or programs that “opt-in”. However, if DEP is turned on for all programs, it can cause issues with some certain programs.

DEP will sometimes shut down a program or process without any notification if it violates DEP. Normally, these are third-party or older programs not written properly for Windows.

You can turn off Data Execution Prevention for a particular program in Windows by following the steps below. Note that you can turn off DEP globally for the entire system, but it’s not recommended as it makes your computer less secure.

Step 1: Right-click on My Computer and choose Properties. Then click on the Advanced tab and then Settings under Performance.

turn off dep

Step 2: Now click on the Data Execution Prevention tab and you’ll see two radio buttons:

disable data execution prevention

Step 3: Go ahead and click on Turn on DEP for all programs and services except those I select.

disable DEP

Step 4: Click the Add button and browse to the location of the executable for the program you want to remove from DEP protection.

After you do this, you should reboot your machine once in order for the changes to take place.

How to add social bookmarking tags using Live Writer

Social bookmarking is used for storing bookmarks of useful web pages on the Net. In a social bookmarking system, users save links to web sites they want on their own social website account. For example, if you have a Yahoo! account, you can click the image below to add the online-tech-tips.com URL to your Yahoo! account:

It would then open your Yahoo! bookmarks page prompting you to save the link:

You could then see the bookmark on the bookmarks.yahoo.com site:

Now that you know how to use the bookmarks when you see them, let me show you how to create link icons for several bookmarking sites so you can put them on your own blogs or web sites. To do this on Live Writer, download the plugin from http://gallery.live.com/liveItemDetail.aspx?li=d2597790-f998-46be-bbe5-caa4a007e0f0&bt=9&pl=8

Click the download button as shown above and then run the file once it is completed downloading.

After running the file, open Windows Live Writer and then make a post where you want to put the icons. Click the Bookmarking Tags! plug-in under the insert panel:

image

Enter the URL of the site you want to bookmark, a descriptive title and “text to show” that will act as a label on the left side of the icons. You may choose from the available bookmarking sites but all are selected by default. Click done to create the icons:

image

If you look on the source code, the plug-in automated the generation of the code and the icons are preloaded also, so you don’t have to figure out the right URL syntax for each bookmarking service.

How to use Symantec AntiVirus Liveupdate

I use Symantec Antivirus as my primary virus protection software. Like any other antivirus tool it depends on it’s virus definitions database to be able to recognize virus signatures that sneaks up on my computer.

In this post I will show you how to use the LiveUpdate window to update Symantec’s virus definition files.

image

To access live Update open the Symantec Antivirus window and look for the LiveUpdate button at the lower right portion of the screen.

image

Before clicking the button first notice the date of the version of the virus definitions file. This way you will see if your definitions file is old or recent. The older this date, the more urgent that you need to update.

image

Click the LiveUpdate button to open the LiveUpdate wizard. Click Next to begin downloading:

image

Wait for the download to finish. That’s it! In some cases you will need to download up to 40MB of files if your virus definition files is really old.

Be patient with it, your antivirus software is only as good as it’s virus definition updates. The download time could take a few minutes to an hour depending on your Internet bandwidth.

By default LiveUpdate automatically downloads the virus definitions from the Symantec server. In some cases, like when I didn’t connect my computer in the Internet for a very long time, I needed to trigger the LiveUpdate manually.

Tips for Increasing Computer Speed and Performance

Keeping your hard drive clean is essential to the high performance that the latest computers can achieve. Fortunately, it's a simple process; one that can easily be performed on a regular basis and, with some organization, keep your computer running like a well-oiled machine

You can discover how much hard drive space is available on your computer by accessing the DriveSpace program in your System Tools. A pie graph will show you the amount of used and unused space for each of your drives. Check this often to keep an idea of how much space you are using..

There are six simple steps to clearing up your hard drive:

1. Uninstall unused programs.

Many times a new program will come along that looks fun to have or play with, but after a week or two you simply stop using it. These programs clutter up your drive and take up valuable space. You might be tempted to delete these programs from your drive, but doing so will cause problems. You must use the uninstall function of Windows for the program to be removed safely and completely.


2. Clean out temporary files.

When your computer is not shut down properly, it will pass information from memory into fragmented files. Also, while you are running programs, your computer will write information that it does not immediately need into temporary files. Installation files will also expand themselves into the temporary folder and will not always clean up after themselves. You can delete these temporary files safely by using the Disk Cleanup option in your System Tools.

3. Empty your Internet cache.

As you surf the Internet your computer stores web pages and images into a temporary Internet cache so that it can quickly recall and access information when you move back and forth between pages. This backup information can quickly add up and eat hard drive space.

Whether you use Internet Explorer, Netscape, or one of the many other browsers available, emptying out your cache is quick and easy. Simply follow the instructions in the Help files located within those programs. You may also wish to set a specific maximum file size for your cache folder, so that it is not allowed to run rampant.

4. Empty your mail programs of clutter.

It's easy to browse through your email and leave old messages there, promising yourself you'll sort them out later. One or two messages don't take up much space, but hundreds certainly do. Take the time to sort through these old emails now and delete what is not important. Create folders and organize what is left. Make it a habit that when new emails come in, they are either filed immediately or thrown away. Set your email program to empty your deleted items folder each time you close your mail program.

5. Empty your recycle bin.

Once you've emptied your drive of cluttering, unnecessary programs; empty your recycle bin to remove what has been placed there in the process.

6. Scandisk and Defrag.

When Windows installs programs, it will put the files it needs anywhere that it finds free space, and not directly after the last program installed. As a result, your hard drive has patches of empty space on it that are not big enough to fit a full program, and will result in a drive space error if you attempt to install something new. Scandisk your drive to check for lost file fragments and to fix any errors it finds, then Defrag to pack all of the program files together at the beginning of your drive. This will clear out those empty patches and move all of the free space you've just created to the end of your drive.

Now that you've got it clean, keep it that way. Perform this quick maintenance routine every week. For your work computer, Friday afternoon before you leave for the weekend is the perfect time. When you return to work on Monday, you'll have a computer that is clutter-free and as responsive as it should be.

Organize your surfing habits. Direct all of your downloads to the same folder, so that you can easily find them and delete them when necessary, or move them to zip disks for storage. Keep track of the programs that you install. For trial versions, note the date that they will expire on a calendar. This will remind you to uninstall the programs that you can no longer use rather than allowing them to clutter up your drive. Also, if you run into problems, keeping track of new downloaded and installed programs and the date they were installed can help you track down the cause of problems.

Remember that the cleaner your hard drive is, the better your machine will respond! In order for your computer to be user friendly, it must have a friendly user. Be your computer's best friend and clean out the cobwebs regularly
