Things you can do to help your PC run better
1. Uninstall Crapware
Though the situation is improving, unnecessary preinstalled software installed by PC makers continues to be an issue with some new computers. A couple of years ago, a Lenovo PC we tested had nearly 20 so-called helper programs installed, and these would occasionally and unwantedly pop up and interrupt what we were doing on the computer. More recently, the count of preinstalled, unnecessary software has dropped. A new HP laptop included just nine of these apps, while a recent Asus model only had five. Even Microsoft is not blameless in this game, though, including a couple of games from King and perhaps some mixed reality software you may not be interested in.
You can simply right-click on any unwanted app tile in Start and choose Uninstall. This will immediately uninstall the program. You can also right-click on the Windows logo Start button, and choose the top choice Programs or Apps and Features. Or just type Programs in the Cortana search box next to the Start button.
You can usually find the culprits by sorting the list of installed apps on the name of your PC maker. Other good options are to sort by Recent to see if there are any programs you didn't know you installed; or by Size, to get rid of very large items you don't need. When you've found junk apps you don't want, simply select them and click Uninstall. Unfortunately, you can only remove one at a time, so set aside a half hour or so for this project if you have a bunch of bloatware. Don't forget to take the hatchet to apps you installed yourself but no longer want, and for software you don't want that was installed alongside software you did want.
Keep in mind, with Windows 10 there are two kinds of applications, traditional desktop ones and modern Windows Store apps. You'll see both kinds in the modern Settings app's Apps & Features page. But for non-Store apps, Control Panel opens, where you can uninstall good old desktop programs. In either, you can sort by size, date installed, or name, or search for a particular app.
One reason removing apps helps performance is that many programs load processes at boot time and take up valuable RAM and CPU cycles. While you're in the Programs and Features section of Control, you can also click Turn Windows Features On or Off and scan the list to see if there's anything you don't use.

2. Limit Startup Processes
As mentioned in the last entry, a lot of programs install side processes that run every time you start your PC, and some of them are not things you need running on your system all the time. Compared with Windows 7, in which you had to run the MSCONFIG utility, Windows 10 (and Windows 8.x before it) gives you an easier way to limit what runs at startup—from the updated Task Manager.
The easiest way to invoke the Task Manager is by pressing Ctrl-Shift-Esc. Switch to the Startup tab, and you'll see all the programs that load at Windows startup. The dialog box even has a column that shows you the Startup impact for each. The Status column shows whether the program is enabled to run at startup or not. You can right-click on any entry to change this status. It's usually fairly easy to see things you don't want to run. For example, if you never use iTunes, you probably don't need iTunesHelper running all the time.
3. Clean Up Your Disk
From the Start menu, type Disk Cleanup. This opens the trusty Disk Cleanup utility that's been part of Windows for several generations of the OS. Disk Cleanup finds unwanted junk such as temporary files, offline Web pages, and installer files on your PC and offers to delete them all at once. You may even find that your Recycle Bin is bulging at the seams. This will generally only have a noticeable effect on speed if your drive is getting close to full, however.
If you don't have disk defragmentation scheduled regularly, set that up in the Optimize Drives tool, which you can find by typing its name in the Cortana search box next to the Start button. Note that if your main disk is an SSD, then you needn't bother with defragging, since there aren't any moving parts reading the disk.
An even newer way to keep storage use is by enabling the Storage Sense option (see image above). This automatically frees up space by removing temporary files and Recycle Bin items. For a full rundown on how to use this feature, see How to Free Up Hard Disk Space on Windows 10
5. Check for Viruses and Spyware
You can run the built-in Windows Defender or Trend (the school anti-virus) to do this, but you're best served by PCMag security guru Neil Rubenking's top pick among malware-cleanup programs, Malwarebytes Anti-Malware—it's free!
6. Change Power Settings to High Performance to Optimize Speed
Of course, this isn't a good choice if you want to save electricity, but it could boost your PC's computing speed. Head to the Settings app's System > Power & sleep option and then click the Additional power settings link. From here, click the dropdown arrow on the right side to "Show additional plans" and then choose High Performance.
7. Run Troubleshooters
Open the Settings app and search for troubleshoot. Windows recommends troubleshooting utilities you should run, and you can choose to run them automatically or manually. For good measure, run the other troubleshooters, including Search and Indexing, Hardware and Devices, and Windows Store Apps. Also go to the old-style Control Panel's System and visit Security > Security and Maintenance page (or just type maintenance in the Start menu search box), click Maintenance, and hit Start Maintenance. This happens automatically on a daily schedule (you can change the time it runs—mine was set for 2 a.m.), but if you're experiencing slowdowns, it's worth trying.
If your PC is still hopelessly bogged down, you can use the Windows Security app's Fresh start option, but be warned that doing so may remove some of your installed programs, but your personal files are kept.
8. Change Appearance in Performance Options
You can easily get to this setting by typing adjust appearance in the Start menu's search box. In the dialog, you can use the radio button at the top labeled Adjust for best performance or select which eye-candy features you can live without from the long list of check boxes below these choices. If you choose the overall best-performance button, you'll lose all of the visual effects. For example, you won't see the contents of a window you're dragging move, but rather just a rectangle representing the window's edges. Keeping the effects that you enjoy checked in the dialog is probably a better way to go. You can also get to this tool from the new Settings app and searching for "maintenance" or "performance."
9. Turn Off Search Indexing
Especially for lower-powered PCs, search indexing can eat up system resources, if only temporarily. If you do a lot of searching, this won't appeal to you, as some searches will be slower. To turn off indexing, open the Indexing Options Control Panel window (you can also just type index in the Start button search box to see Indexing Options at the top of the result list). Click Modify and uncheck locations you don't want indexed. Choosing Advanced lets you decide which file types should and shouldn't be indexed.
If you leave search indexing on but find that it occasionally slows down your PC, you can stop its process when you need extra speed. Right-click This PC on the desktop (or type Computer in the Search box), and choose Manage. Then, double-click Services and Applications, and select Services.
Find Windows Search, and double-click on that. From this Properties dialog, you can choose a Startup type of Manual or Disabled to have the process silent by default. The Automatic (Delayed Start) startup type according to Microsoft help, "is preferred over the Automatic startup type because it helps reduce the effect on the system's overall boot performance." That may be turned on by default.
A final option is to go to the right-hand panel, click More options, and then Stop. You can also simply hit the stop button above the center section. Don't forget to turn it back on at some point if you want to be able to search your system.
10. Turn Off Tips and Notifications
It may seem odd for a tips article to tell you to turn off Windows 10's Tips feature, but it can reduce processing that Windows needs to do to display relevant tips for your system. The same can be said for Notifications. If Windows doesn't need to generate a notification, your computing will go faster. I have over 40 apps that are capable of sending notifications. Simply open the Settings app's Notifications & actions page to change the notification settings. You'll see a list of individual apps that can send notifications, and you can uncheck those you don't want to hear from. If you have a lot of these, too, go through the list and you're bound to find sources from which you have no need to be notified. The distraction savings alone can speed up your PC use, if only in terms of your perception of computing speed. An easy way to pause notifications is to tap the Focus Assist button in the Action Center. This also makes it easier to re-enable them later.
