Clean-up Your Temp Folder

The “Temp” folder contains the temporary files in Windows. The files which are to be used by the system temporarily are stored in the Temp folder, like the files used by the running programs or the files waiting to be burned to a DVD.
The files in this folder are flushed after the computer is shut-down, but sometimes this doesn’t happens and the folder gets junky with some unuseful files which can result in the decrease in the performance of the system.
To avoid this, we can manually delete the temporary files manually, or by creating a BAT file that automatically cleans-up the Temp Folder (the hacker’s way).

Deleting manually:

  1. Type “%temp%” in Run (Windows Logo Key + R). This should pop-up the Temp folder.
  2. Select all the files (Ctrl + A) and delete them.

Deleting by using a BAT file:

  1. Copy the following to your favorite text editor and save it as “ClearTemp.bat” and select “All Files” in the “File Type“.
    del %temp% /F
  2. Confirm the action to delete the Temp files. Then it would give you a list of files which weren’t deleted because they were in use.

Add Your Favorite Folders to TaskBar

Are there any Folders which you visit very often? If yes, then a good news for you!
After reading this post you’ll be able to browse your favorite folder(s) without opening the Explorer Windows, via your StartBar, just like you browse the StartMenu!

  1. Right-Click on TaskBar, and go to “Toolbars>New Toolbar…“.
  2. In Windows XP, select the path/folder/directory option and then choose your Folder which you want to appear in TaskBar.
  3. In Windows Vista, the first step will pop-up a window that prompts directly for the Folder.
  4. After you have done that, you will see your favorite folder in the Taskbar, which opens just like a menu!

Change the Default Program Installation Location

The default folder in Windows where your Apps are installed is C:\Program Files. There’s a registry hack which allows you to change this default location to any other location of your wish. The Installation dirctory can be manally chosen while installing an App, but it’s better to apply this hack if you want to permanantly install Apps in any other directory except C:\Program Files.

Here are the steps to do it:

  1. Open Registry Editor (Windows Key + R, and then type “regedit” and hit Enter).
  2. Browse to this direcory : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
  3. In “CurrentVersion“, look for “ProgramFilesDir” and double-click on it.
  4. In the “Value data“, enter the desired location.
  5. Hereafter, the Apps will be installed in the directory that you choose.

This trick can be useful if the C: drive is out of space and you want to shift apps to any other drive!

In-Built Scientific Calculator in Windows

The classic Calculator that you get with Windows has a “scientific” mode in it, which allows you to easily do scientific and complex calculations on your computer.
Here are the steps to get your Windows Calculator into scientific mode:

  1. Open Calculator (Windows Key + R, and then type “calc” and hit Enter).

    Opening Calculator
    Opening Calculator
  2. Go to “View” and choose the option “Scientific” from? the menu.
  3. Switching to Scientific Mode
    Switching to Scientific Mode

  4. Then you’ll see a calculator that has got a lot of things to get you going through your calculations.

Shutdown & Restart Shortcuts

Don’t you think the process of shutting down or restarting the computer consumes a lot of time??
Let’s cut-short this process…its really easy :)
Just create a shortcut to “Shutdown” or “Restart” and assign a shortcut key to it.

For Creating a Shutdown Shortcut

  1. Right-click anywhere and in the menu, go to “New” and then click on “Shortcut“.
  2. A dialogue box would pop-up asking for the Target or the Location of the item for which you’re creating the shortcut.
  3. In that box, type “shutdown -s -t 000“. The “-t 000” in this command stands for the timer of shutdown, the “000” is the time after which Windows will Shutdown.
  4. Then, give a name to the shortcut which will help you to identify it.

Now, assign a shortcut key to your shortcut…

  1. Right-click on your shortcut that you made just now, and click on the “Properties”.
  2. In the “Properties“, go to the “Shortcut” tab. Look for “Shortcut Key” over there.
  3. In the “Shortcut Key” box, press the keys that you want to assign to your shortcut (Mine is “Ctrl + Alt + S“)

For Creating a Restart Shortcut

Follow the same steps taken for creating a Shutdown Shortcut, just replace the “shutdown -s -t 000” command with “shutdown -r -t 000” and give it a diferent name.
Then you can create a Shortcut Key using the steps given earlier.

I gurantee that if you shutdown or restart your computer using the Shortcut Keys, the time taken in the process will be 70% less than the total time that was taken before. :P

ISRO’s Bhuvan vs Google Earth

ISRO Logo

The India Space Research Organisation has done a lot for the advancements of Space Research & Administration in India. ISRO created history by the launch of Chandrayaan. And it has established two main Space Systems: INSAT & IRS & has developed two satellite launch vehicles PSLV & GSLV to place INSAT and the IRS satellites in the required orbits.

Now, ISRO is up with Bhuvan to compete with Google Earth. “Bhuvan” is a sanskrit word meaning “Earth”. Bhuvan will provide services similiar to Google Earth & Wikimapia, but it will be confined only within India.

Bhuvan has some special features which sets it aside from Google Earth & Wikimapia. It will have a better zooming efficiency, multilayer viewing technology, and it will update its data yearly unlike Google Earth & Wikimapia which update their data in 4 years. Using the multilayer technology, we can see data from the past dates also!

According to a article at TOI:

Bhuvan allows you to zoom far closer than the aerial view from a chopper. If Google Earth shows details upto 200 meters distance and Wikimapia upto 50 meters, Bhuvan will show images upto 10 meters, which means you can easily see details upto a? three floor high building and also add information.

And the last fact, ISRO’s Bhuvan will be using indian satellites.

Here’s a table of comparison of Google Earth & Bhuvan from Wikipedia:

Feature Google Earth Bhuvan
Max Zoom 200m 10m
Layer Single Multi
Update Frequency 4 yrs 1 yr
View Viewing from only one date. Options for viewing from different dates.
Source (Satellite) Commercial/International Indian
Imagery World World

I hope to see this ISRO’s new innovation go live soon. :)

Multiple GTalk Simultaneously

Have Multiple Google Accounts?
And want to login with both of them on Gtalk on single PC?

This is what I wanted to do as I’ve got two Google IDs, so I found out the way to run multiple GTalks simultaneously…

How to do it:

  1. Create a shortcut to GTalk on your desktop (if you dont have currently).
  2. Go to the properties of the shortcut. There in the target, you’ll see something like: “C:\Program Files\Google\Google Talk\googletalk.exe”
  3. Add /mutex to that target line. Then the line would be : “C:\Program Files\Google\Google Talk\googletalk.exe” /nomutex
  4. “Apply” it and then click “Ok”.
  5. Check out if it works, Enjoy Multi-GTalks!

Don’t forget to leave comments here if this works…[:)]

How this Works:
The mutex is short for mutual exclusion object. A mutex is a program object that allows multiple program threads to share the same resource, but not simultaneously.

So, in the hack above, we used nomutex (no-mutex) so to use the same resources simultaneously…

‘File and Printer Sharing’ Exploit (Continued)

As I said in my recent post, I am here with the ways to secure “File and Printer Sharing”.
Here they go:

  • Don’t enable File and Printer Sharing if you don’t have the need for it, I mean if you don’t have a LAN or if you don’t have to share any Files or Printer with a network computer.
  • When having the File and Printer Sharing enabled, Password-protect the shared drives. This can be done by clicking the “Make this Folder Private” option under the ‘Sharing’ tab under the ‘Properties’ of the shared drive.
  • Don’t share the root of a drive. If you have to share specific files and/or folders then drag them diretly to the “Shared Documents” Folder.
  • To disable the File and Printer Sharing, go to “Network Connections” and check the properties of your network (usually named ‘Local Area Connection’) and uncheck the “File and Printer Sharing for Microsoft Networks”.
