Accelerate the system during the defragmentation process(Windows XP, Vista, 7)

              As soon as a defragmentation starts, your system becomes very slow and hardly becomes available for normal use. You want to work faster again.

              During defragmentation, a security program might also be active, for instance a virus scanner. Both processes hinder each other as the security program detects every change made in a file because of the defragmentation and then reanalyzes it. Normally, this is a good precaution, but it costs a lot of computing power and you can be reasonably sure no malware is at work.
              To ensure a safe work environment, first disconnect the PC from its network and Internet connections. For that, you can use the Wi-Fi switch on a laptop or unplug the network cable. You can also deactivate the relevant connection for the time being. As the next step, end the security monitoring by right clicking the applicable program’s icon in the taskbar and select the its stop/pause command. Specify the desired time period, then complete the defragmentation without interruption. You can continue to work in the mean time with Office programs or play local media files. Finally, do not forget to reactivate the security program or to restart the computer.
