That usually means something (hopefully minor) is amiss on your system. Maybe your computer is running low on memory because it’s doing a few too many things at once; or, perhaps, the program you’re using has wandered into a corner that it can’t get itself out of.

Now, the best way to deal with either the spinning Windows disc or the Mac’s beach ball is, typically, to do nothing. With any luck, your system or application will settle down after a few seconds or so.

But if several minutes have passed and you’re still staring at a frozen program, it might be time to take matters into your own hands and force the stalled program to quit.

Doing so may, of course, lead to losing any unsaved data; then again, you may not have much choice.
Ready to unstick a stuck program? Here’s how.

Stuck with a frozen Windows program? Open the Task Manager, select the app that’s causing you trouble, then click the End Task button.

For Windows:

• If you’re still seeing the spinny circle after waiting a few minutes, it’s probably time to call up the Task Manager, a tool that details all the programs and other system “processes” that are currently running on your PC. To do so, press and hold the CONTROL, ALT, and DELETE keys all at the same time, then click the Task Manager option.
• Once Task Manager is running (if you’re using a Windows 7 PC, make sure the Applications tab is selected), check out the list of running programs; you should see the misbehaving program flagged with a status of “Not Responding.” Click the program, then click the “End Task” button at the bottom of the Task Manager window.
• Next, you’ll be prompted to either a) wait a little longer for the program to right itself, or b) go ahead and quit the program. Waited long enough? Then click “quit.”

You can force a frozen Mac program to quit in just a few clicks.

For Mac:

• Open the Apple menu (just click the Apple icon in the top-left corner of the screen) and select “Force Quit”—or, if you like, press the COMMAND, OPTION, and ESCAPE buttons all at the same time.
• You should now see a list of all the running programs on your Mac, including the application that’s frozen (probably labeled “Not Responding”). Click the name of the program, then click the “Force Quit” keys in the bottom corner of the Force Quit menu.
• A prompt will appear warning that you may lose any unsaved changes if you force the program to quit. Ready to put your program out of its misery? Click the Force Quit button once more, or Cancel if you’re rather wait it out.

The Windows 8 Task Manager has a nifty feature that not only lists all the programs that launch when your system starts up, but also rates the “impact” they have on your PC’s startup speed.

Now, some “high” startup-impact programs will probably be ones that your system can’t live without—like, for instance, the “Rundll32″ application, an essential Windows app that helps other Windows program access shared “libraries” of computer code.

Others, however, may be programs that you forgot you even installed—and now they’re sitting on your PC, launching themselves whenever you start your system and gobbling up precious system resources.

So, ready to put a leash on programs that are slowing your system right out of the gate?

Not sure what a specific startup program does? Right-click its name to get more details.

Here’s how…

• To launch the Task Manager, just start typing “Task Manager” from the Windows 8 Start screen; you should see the Task Manager sitting at the very top of your search results. If you’re already in the “classic” Windows desktop, just press and hold CONTROL + ALT + DELETE and select Task Manager from the menu.
• If it isn’t already, toggle the “More details” setting at the bottom of the Task Manager window to reveal a series of tabs at the top of the windows, then click the “Startup” tab.
• You should now see a list of all the programs and processes that launch when your PC starts up. Click the “Startup impact” heading to sort the list from “High” startup impact to “Low.”
• Now, take a look at the programs that are having the greatest “impact” to your system’s startup time. See any you don’t need? Select the slowpoke and click the “Disable” button to keep it from launching itself when your PC starts up. (I, for example, spotted Facebook’s “Messenger” app—which I never use—near the top of the list. Yep, it’s now disabled.)
• Not sure what a particular startup program is for? Right-click its name and select “Open file location” to find out where the app sits on your hard drive; you can also “Search online” for more information or inspect the program’s “Properties.”
• Change your mind about preventing a program from starting when you power-on your PC? Just open the Task Manager, select its name under the Startup tab, then click then Enable button.
