Here are the 5 basic steps to speed up windows 7

With Windows 7, Microsoft did an actually good job making the scheme present well. However, over time, Windows 7 schemes can slow down and need some care and feeding to retrieve their previous glory. Further, some Windows 7 features can be leveraged to advance overall scheme presentation. In this article, I will summarize 5 steps you can take to boost the presentation of your Windows 7 systems.

1: Disable unnecessary service - Not every system that is running on a stock window 7 machines is necessary. A number of services can either be disabled to run only when needed. Once you modify, the service is no longer has to munch through system resources and the system no longer has to spend time starting the service.

 2: Reduce the number of startup items – Windows 7 systems finally start to bear under the weight of software that is established in the usual course of enterprise. Numerous programs titles establish more than is necessary and encompass helper applications designed solely to make the software start up more quickly or facilitate other communication.

You could go through your scheme device by device and remove the offending programs, but you might desire to keep the underlying device around and just prevent the helper from stacking. This and more can be accomplished through the use of MSconfig, a tool that has long been a part of Windows. MSconfig permits you to selectively disable startup items and take other steps toward improving general system performance.

3: Remove the bloatware installed by vendors - I've long sensed that Microsoft's OEMs sometimes actively work against the Redmond behemoth and sully the company's title. Nowhere is this more apparent than in the case of what has become known as "bloatware."

4: Keep viruses and spyware off your system – If you're running Windows, you need to be running an anti-malware program to hold viruses and spyware off your system. Not anything will wreck good performance like a boatload of spyware. My individual very popular (and free!) tool for tackling malware is Microsoft Security Essentials.
