Instant Screen Capture, Upload And Sharing

Screen captures are one of the most widely used features from a computer user’s point of view. In some capacity, they are used by almost everyone. We have covered a few tools in this category, and yet there is always a new tool that offers something new, something different. So holds true with Gyazo.

Its a small, lightweight tool whose developer dubs it to be ‘seriously instant screen-grabbing”. When launched, the application turns the mouse pointer to a crosshair. Drag and select the area you want captured, and the moment you release the mouse button, captured area gets uploaded to Gyazo’s servers and the URL copied to clipboard.

You’d be justified in asking, what’s the point? First, Gyazo makes screenshot sharing a complete breeze. With the uploaded image, other than sharing the URL manually, you have 3 buttons to share on Twitter, Facebook and Flickr directly. The screenshot taking process is really simple, and also shows the pixel resolution of the screen area being captured. Furthermore, if you drop any images on the Gyazo icon on your desktop, they instantly get uploaded to Gyzao.

On the downside, you cannot modify or even delete any uploaded images as of yet.

Gyazo is available for Windows 2000 through Windows 7, and also for Mac and Linux.

10 Ways to Make Your Laptop Run More Efficiently

Whether it’s for work or pleasure, a laptop can be a real joy. However, if your laptop is not running as fast as it did when it was new, it may be time for some routine maintenance and cleanup.

Here are a few simple tips that you can use to make your laptop run faster, and last longer:

1. Defragment your laptop on a regular basis – at least once a week. Your computer breaks all of your files up into many pieces, and scatters them throughout your hard drive.  What defragmenting does is take all these mixed and scattered pieces, and re-organizes them neatly into a space where they can be easily accessed more quickly – The Best Free Defragmentation Tools.
2. Cleaning your Registry is a must. One of the most important parts of Windows is the registry . Fatal errors to your laptop can occur from disfiguration or corruption of this section. The most common cause of registry problems is buggy software installation.  Keep your registry clean and consider getting and running a registry cleaner from time to time. There are many of these programs available online, and some of them are even free – Keep Your Registry Clean With Mr.Fix – Registry Cleaner.
3. Unclutter your hard drive of unnecessary programs and files such as entertainment, games, music, pictures, etc. If you allow them to add up, these files can clog the hard drive and slow it down. If your hard drive is too full, it can also cause problems with your computer’s RAM and processing capability. This can lead to significant slow-downs and frequent crashes – Windows Cleanup for Fast and Fun Cleanups.
4. Get good virus protection. You need to run a good anti-virus program and spyware/adware program at least once a week, if not more. Many people do this every day at start-up. Most of these programs are able to run automatically on their own schedule without your assistance, which can save you a lot of time .
5. Empty the recycle bin regularly. It doesn’t do you a lot of good to delete all that unnecessary junk if it’s just going to sit in your Recycle Bin. No one likes taking out the trash but it needs to be done! –Recycle Bin tips and tricks.
6. Erase temporary Internet Files. This cannot be stressed or emphasized enough. Every time you go to a site on the web or open a file, a temporary copy is made and kept in your hard drive. They may be called "temporary" but they’re there for a long time. The more you have on your system, the more they’re going to slow down your laptop. Whether you’re running Firefox, Chrome or Internet Explorer, find out how to clear your browser’s cache, and do it regularly – Delete Internet History, Cache and More.
7. Get rid of unnecessary startup programs. Many programs want to start running as soon as you boot up your computer. Although these programs may not always be visible on your desktop, they’re still running in the background and sucking up your valuable RAM. This can significantly slow down the laptop as time goes by. Find out how to modify your "msconfig", and manually remove these programs from launching on startup. You won’t be removing them from your computer, just preventing them from running every time you start up your computer – The Best Startup Managers.
8. Keep your laptop running cool. Avoid keeping your laptop directly on a soft surface such as your bed or couch. It needs to be able to breather freely and allow air to circulate. Otherwise, your processor might overheat, causing slow-downs, crashes and even physical damage to components.
9. Uninstall unused programs. Any programs that are not being used are just taking up space on your hard drive. Please note that deleting a program folder is not the same as uninstalling. Make sure to properly remove programs using the Uninstall function in your control panel. Otherwise, you could just end up creating more problems – Best Uninstallers for Windows.
10. Upgrade your RAM if necessary. If you have a tendency of having many large programs all opened at once, you may not have enough RAM on your system. Look into purchasing some new RAM. Prices are very reasonable, and it’s a cost-effective way to increase the speed and efficiency of your laptop.

If you follow the advice listed in this article, you can possibly get an extra 2 or 3 years of life from your laptop before you’ll need to replace it.

But remember… before doing any kind of work on your system, it’s vital that you create a backup copy of all your most important data. This way, you’ll be prepared in the unlikely event that something goes wrong.

Boot Or Start Computer Faster

Many computers take a lot of time to boot (or start ) this is due to many reasons.
Some slight changes can do wonders for your system:


1. Press start->run then type msconfig and press enter.
Go to the startup tab. Here you will see a list of startup items. These
are all the programs that automatically start when you boot your PC.
It is these that slow down the boot up process.
                                 So uncheck all the unwanted items like ms-office,
messengers other utilities that u may not need at startup). Don't
uncheck your antivirus software.
Restart your Pc to and see for yourself, your pc will now boot faster....


  
2. A great new feature in Microsoft Windows XP is the ability to do a
boot defragment. This places all boot files next to each other on the
disk to allow for faster booting. By default this option is enabled, but
on some systems it is not, so below is the information on how to turn
it on:
Go to Start Menu and Click Run
Type in regedit then click ok
Find
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOpt
imizeFunction"
Select "Enable" from the list on the right
Right on it and select "Modify"
Change the value to Y .
Reboot your Pc and see the change yourself.


3.SPEED UP BOOT BY DISABLING UNUSED PORTS.!!
You may have tried many tweaks like modifying windows XP start-up
applications, prefetches, unload DLLs method, etc. And yes those
methods do work for me.
                    I have just accidentally found out another way to give you
an extra boost in windows XP's boot performance. This is done by
disabling your unused devices in Device Manager. for example, if you
don't have input devices that are connected to one of your USB's or
COM ports, disabling them will give you an extra performance boost
in booting. Go to Control Panel -> System -> Hardware tab -> device
manager Disable devices that you don't use for your PC and then
restart.

Trick to lock your private folder without any software

Do you worry about privacy or do you maintain some personal
files on the office system or at Friends pc, then you must lock that
folder. I know many software's that most people use to lock their
Personal files. But this trick is the safest and locks files or folders
without use of any software's.
Suppose you want to lock the folder data in c: which has the
path C:\data.


USING BATCH FILE ::-


In the same drive create a text file and type
ren data data.{21EC2020-3AEA-1069-A2DD-08002B30309D}
Now save this text file as loc.bat
Create another text file and type in it
ren data.{21EC2020-3AEA-1069-A2DD-08002B30309D} data
Now save this text file as key.bat
Now you can see 2 batch files loc and key. Press loc and the folder
movies will change to control panel and you cannot view its contents.
Press key and you will get back your original folder.
try it out!!!!!!!
Note: It is safe as in case if you loose the key file, you can create it
again but the folder name must be correct.

Note:You must not lock folders like My Documents,My Pictures....and all System folders and Program folders.

You can use following Hex codes to change the icon to something other than the control panel. Here are the keys to do so:

USING REGISTRY TWEAKS ::-

Here i will explain how to lock a drives. Generally everyone don’t usually prefer to lock their drives, but sometimes it becomes nesscary. Say for instance you might have stored your important documents in D:\ and you don’t want others to access them, in such case this technique can be useful for you. Please don’t try this tweak with your root drive (usually C:\ is the root drive) since root drives are not intended to be locked because they are mandatory for the system and application programs.

1. Go to Start & Run and type Regedit to open Registry editor.

2. Browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer

3. Now create a new DWORD value NoViewOnDrive and set its value as

2^ (Alpha Number of Drive Letter-1) where Alpha number are simple counting of alphabets from A to Z as 1 - 26

For example: to lock C:\, Alpha number of C is 3 so 2^ (3-1) = 4 (decimal value)

4. To lock more drives , calculate the value of each drive and then set sum of those numbers as value.

5. To unlock your drive just delete the key from the registry.

Note: Dont lock your drive where your Operating System resides.

USING COMMAND PROMPT ::

1. Go to Start,Run and then type CMD to open Command Prompt window.

2. In the command prompt, go to the drive where your folder is present. For example, i want to hide some folder called Data which is present in C:/Data . Go to C:/ .

3. Now type the command attrib Data +s +h and press ENTER. Here 'Data' is the folder name. Now the entire folder is hidden.

4. To unhide the folder, simply type attrib Data -s -h and press ENTER.

You can apply this method for both files and folders. You have to remember the folder or file name and its location. Since there is no other method to find hidden folder or file. So note down and keep it in a safe place.

Note: You may find some issues with this method.

ENJOY!!!!!!!!!!!!!!!!!!!!!!!!!!!
