5 programs to defragment your Hard Drive!

Last week, we had featured Registry Cleaning programs for Windows to keep Windows top. This is a follow-up for that post, here we explore file fragmentation and its impact on computer performance.

Why do you need Disk Defragmenter?

All modern day operating systems like Microsoft Windows (sometimes on Linux, Mac OS) etc are prone to file fragmentation. File fragmentation is a condition where file blocks are way too scattered and this condition considerably slows down your computer’s performance. Primary reason for this is that your Hard Disk head needs to move (seek) around too much to read the file blocks. Disk seeks are slow comparatively and slows down your overall system performance. Fragmentation of files is very common on Windows, however, not a major problem on operating systems like Linux.

So it is recommended that you keep defragmenting the files with the help of tools that bring all file blocks which are best kept sequentially together.

Autoruns – Hunt those nasty startup programs that slow down your bootup!

Your new PC or newly Installed Windows OS behaves well and fast. Over a period of time, the behavior changes. Every application launch takes more and more time. You get dissatisfied with your PC bootup time. Why? If you look at your Task Manager process list, you see a lot of processes running and taking a lot of your RAM. It is a fact that, installing newer applications add additional entries in your Windows startup so every time, windows boots, it has to process those additional tasks and launch extra third party processes. Most of them are background processes and you will not even notice. Some of them are essential but mostly a nuisance.

It is highly recommend that every now and then you need to keep an eye on your startup tasks list. A simple tool msconfig (Microsoft System Configuration Utility) is very popular. But it is not that comprehensive. A new tool is out there from Sysinternals, called Autoruns.

Autoruns has the most comprehensive knowledge of auto-starting locations on Windows. It shows you what programs are configured to run during system bootup or login, and shows you the entries in the order Windows processes them. It runs on all versions of Windows and will surprise you with the list of tasks that run during bootup. You will say “Hmm. That’s why my PC is slow!”. Carefully see what are those nasty apps that you don’t want to run during bootup and disable them. Please be careful on what you disable as it might be a critical Windows service. Make sure you hide all Microsoft auto-start list.

Download and run Autoruns and it shows you the currently configured auto-start applications in the locations that most directly execute applications.  Perform a new scan that reflects changes to options by refreshing the display.
