Keep in mind that the actual deletion of junk files and any needed system changes aren’t removed or applied until you start the opti- mization process. Step 1: Open PC Pitstop Optimize Before you can begin, you have to open PC Pitstop Optimize.You can usually access this program from the Start menu by browsing to the following path: Programs (or All Programs) ➔ PC Pitstop ➔ Optimize Then click PC Pitstop Optimize, as shown in Figure 4-1. Figure 4-1: Opening PC Pitstop Optimize via the Start menu Step 2: Specify Initial Settings After starting PC Pitstop Optimize, you will see the welcome screen, as shown in Figure 4-2, and a few settings you need to specify. First, you need to select an Internet Connection Type from the drop- down list, as shown in Figure 4-3: 22 Part II • Optimizing Your PC 09_068557 ch04.qxp 12/13/06 6:12 PM Page 22 Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark.

If you aren’t sure that PPPoE is used for your Internet con- nection, you should use the Safe option instead (discussed in the preceding bullet) to prevent any potential problems. Note Point-to-Point Protocol over Ethernet (PPPoE) is a protocol specifying how a PC interacts with a broadband modem (i.e., xDSL, cable, wireless, etc). It provides the Internet service provider (ISP) with better control over how their customers log into the network and use network resources. From an Internet optimization standpoint, the important thing about PPPoE is that its maximum packet size is slightly smaller than non-PPPoE connections. In most cases, Windows can detect this situation and adjust automatically with the cooperation of the website being contracted. The Safe settings are designed to accommodate situations where the website does not know how to request a PPPoE-friendly packet size. If the Max option is selected, and connection problems materialize later, open and run the Optimize program again, but with the Safe option selected, to override and undo the Max settings. Then you need to specify the Maximum rated download speed from the drop-down list, as seen in Figure 4-4. 24 Part II • Optimizing Your PC 09_068557 ch04.qxp 12/13/06 6:12 PM Page 24 Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark.
