Review Windows settings to see whether some options are slowing the PC's performance. Adjust the cache and ensure that the system is being protected.
- [Instructor] To help you fine tune your PC's performance, Windows comes with the Performance Options dialog box. In this movie I show you how to use that dialog box to ensure that your computer system is providing you with its full potential. To bring up the Performance Options dialog box, tap the Windows key, and type performance, or some part of it, choose the item Adjust the appearance and performance of Windows. The Performance Option dialog box has three tabs, and I confess, most of the settings are optimized, so you probably don't have to do anything.
Still, when performance suffers, you can try to squeeze a bit more power from the system by turning off a few of these items on the Visual Effects tab. In fact, you might be annoyed by these items and find that turning them off, makes using Windows more enjoyable regardless of the PC's performance. For example, Show shadows under Windows. This setting taxes the PC's graphics processor a wee bit. You can disable it, and then click Apply. See how the shadow around the window disappeared? I'll bring it back.
Now look at the lower right corner of the window. Each of the settings in this list have similar effects, but when you remove them all, you might see a small performance boost. In fact, when you choose the option Adjust for best performance, they're all disabled. In a way, this option's name is kind of a confession about how useful these items are to your PC's core mission. The Advanced tab is home to two items. The first deals with processor scheduling, in my opinion, my programs deserve all the power.
The second item, virtual memory, was once one of those Windows secrets people would use to enhance system performance. The paging file helps in situations where the computer lacks enough memory to get work done. If even if your PC is brimming with RAM, once you start running too many programs at once, the paging file is called in to help supplement a lack of memory. A chunk of memory, referred to as a page, is saved to mass storage. Once that's done, the memory used by that page is available for use by something else.
The problem with this trick is that performance suffers as memory is swapped back and forth to disk storage. If your PC has an SSD, or solid state drive, then swapping works quickly, otherwise a delay can be detected. You'll notice the memory swap the most when you switch programs. For example, if you had a lot of high powered programs open on the screen, say video editing, Word, a database, something that uses a lot of power, you would press alt + escape to cycle through each of these programs.
As you did, you would notice a delay. When the programs switch, the paging file is loading memory to disk back and forth, that's what slows down the system. To improve the situation, my best advice is to add more memory to your computer. When that's not an option, you can adjust the page file size. Click the Change button. Windows prefers to set paging file size, which is really the best option. You can make adjustments by removing the automatic checkmark and setting cache size values on your own.
And you see on this computer, it's just too sophisticated and too fast to even need a paging file. Still, no matter what your choices, this solution is just a work around to adding more physical memory or RAM to the PC. I'm going to cancel because it's okay for Windows to manage the cache, which of course it's not doing because this computer is pretty beefy. Finally, the Data Execution Prevention tab contains one option, which is activated provided your computer's processor supports it. DEP is more of a security feature than a performance tool.
It prevents programs from running in specific parts of memory, locations where viruses or other malware, may launch from. Keeping this item on, prevents all programs from starting in that protected memory, so it's a good thing. And I suppose it has to do with performance because malware and spyware most definitely hinder your PC's performance. Dealing with those digital scourges is the topic of another movie in this course.
