A blog on Windows…

What is an Operating System? A good answer would be “A set of programs that provide a GUI to interact with various devices in a computer”. This definition would hold good until a few years back, when an operating system is just a few icons and menus that you see when you switch on your computer. Operating systems provided file and device management using a Basic GUI.


But with the development of computers, operating systems also evolved a lot. From simple file and device management solution, modern day operating systems should be stable and secure the data stored on a computer. The data stored on a computer can be anything from music, movies and photos to data that you have generated and stored in different files. It takes only a small virus, a power surge or a device failure to destroy data.

Today’s operating systems try to anticipate such scenarios and issue warning messages and take pro-active steps to minimize the data loss. I would talk about Windows XP and Windows Vista because 80% of computers run on Windows Operating system and Windows Vista is an upgrade to Windows XP.

Windows XP has been around for 8 years now and in considered one of the best operating systems released by Microsoft. When Windows XP was released it was considered a resource hogger. Windows XP required 128 MB of RAM to run smoothly. And there are many complaints from long installation times to frequent crashes. Microsoft released Service Pack 1 and things changed. Most of the security holes are fixed and Windows XP became stable. Windows XP was built to give a better user experience by easy installation and plug & play capability.

After a few years with XP, internet threats have grown and Microsoft started bundling Anti-spyware products along with Windows XP. This didn’t help much, and since Windows XP is the most used, hackers tried to find ways to break into Windows XP systems. This triggered the need for a more secure operating system and there came Windows Vista into picture.

Some of the problems with Windows XP are that password protection is not secure enough, users can use Bootable live CD’s like miniPE or Road Starter to bypass Passwords and access the file system. The other major issue is Internet Explorer 6 which is the number one target for hackers. By exploiting the security homes in IE6 hackers can take control of IE and hence the Windows XP box. And last but not least, when you try to search for a file under Windows XP, you have a terribly slow search tool.

Now its Windows Vista which is structurally more robust and is much more visually appealing. Vista comes with Encrypted File System (EFS) which takes care of file level security. Vista allows one to encode an entire partition or hard disk with just a few clicks. In Windows Vista Internet Explorer runs with restricted permission. If a malicious piece of code enters the system through the browser it cannot do much harm, since Vista simply refuses to permit to run it. File Searching has improved a lot with Vista.

But 2 of the night mares with Vista are getting your old hardware running and the annoying popup prompting you to allow or block any action you have performed.

Top 5 Ways To Make A Computer Run Faster

Today I am going to be talking about different ways you can make a computer run faster. There is actually a lot you can do yourself that will boost your PC’s performance. So lets take a look at different ways we can remedy that slow computer of yours!

1. Free Up Disk Space

A great way to make a computer run faster is to free up some disk space. Windows comes with a disk cleanup tool that helps you free up space on your hard disk. The utility identifies files that you can safely delete without messing anything up, and then enables you to choose whether you want to delete some or all of the identified files.

How to use disk cleanup tool.

* Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.

* In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list. (If you have multiple hard drives you will have to select which one to scan.)

* Clear the check boxes for files that you don’t want to delete, and then click OK.

* When prompted to confirm that you want to delete the specified files, click OK.

2. Use Defrag Tool

When you add a file or a new program to a new computer, the hard drive is relatively empty so new data is saved to the hard drive in one whole block. When you need to use that information, the computer can quickly access it because it is all in one place. Defragging your system is definitely a way to make a computer run faster.

How to use defrag tool.

* From the start menu point to “all programs”
* Point to “Accessories”
* Point to “System Tools”
* Click on “Disk Defragmenter”
* The disk defragmenter will display the hard drives on your computer. Just select and click Defragment.

3. Get rid of spyware


Spyware is software with malicious intent – by design; it does something bad to your computer. Usually, it gets installed without your knowledge. It sometimes takes advantage of the fact that most people click “I Agree” to software licenses without reading them.

The only way to get rid of spyware is to have some kind of scanner, sort of like an anti-virus. In order to make a computer run faster and keep it safer your going to need an anti-spyware program. This is tricky, a lot of the spyware programs out there are malicious and will actually add viruses and spyware to your computer by using the “spyware scanner and blocker”. So please remember to be very careful when choosing your anti-spyware program.

4. Find and repair disk errors

Detect and Repair Disk Errors

In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

How to run the error checking utility.

* Click Start, and then click My Computer.
* In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
* In the Properties dialog box, click the Tools tab.
* Click the Check Now button.
* In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
* If bad sectors are found, choose to fix them.
Tip: Only select the Automatically fix file system errors check box if you think that your disk contains bad sectors.

5. Get an external hard drive

Adding an External Hard Drive to your computer will allow you to clear out a lot of the things you don’t need to be storing on your normal hard drive.

A great example would be your music or pictures. All those songs and pictures are sitting on your computer making it go slower. You will see a decline in your computers performance as soon as you use over half of your hard drive space.

Moving all your songs or pictures to your external hard drive will free up a lot of space on your main hard drive. You can even move applications such as photoshop or games.

An external hard drive is also handy because it is portable. You can unplug it from your computer and take it to a friends house and plug it in there, sharing photos and pictures very easily.

This is truly a great way to make a computer run faster.
