You may be curious to know which version of Windows you’re running on your current machine. Here’s the easy way to tell:

 If your Start screen resembles the one in Figure 3-1, you have some version of Windows 8, 8.1, RT, or RT 8.1. Swipe from the right or hover your mouse cursor in the lower-right corner, and then choose Change PC Settings. Click or tap PC and Devices, then PC Info. You get a report like the one in Figure 3-2.FIGURE 3-1: A Start screen like this is a dead giveaway for 8, 8.1, or RT.

 If you have a desktop like the one in Figure 3-3, you're running some version of Windows 7. Click the Start icon in the lower-left corner, then Control Panel ⇒ System ⇒ Security. Under System, click View Amount of RAM and Processor Speed. You see a report like the one in Figure 3-4.

 If your desktop doesn't look like Figure 3-1 or Figure 3-3, you're running Windows Vista or XP. Click the Start icon in the lower-left corner, then click Control Panel ⇒ System ⇒ Security. Under System, click View Amount of RAM and Processor Speed.

If you have a 64-bit system installed already, you should upgrade to a 64-bit version of Windows 10. If you currently have a 32-bit system, check Steve Gibson’s site, as mentioned in the preceding section.

But if you have a different-looking screen, chances are very good you already have Windows 10. Here’s how to see which version you have:

1 In the Search box in the taskbar, type about.Search results are immediately shown, and at the top of the stack you should see something like About Your PC.

2 Press Enter or click About Your PC.You see an About window like the one in Figure 3-5.

3 On the right, scroll down until you can see Device Specifications.To the right of the System Type heading, you see whether you have a 32-bit or 64-bit version of Windows.

4 Scroll down farther until you can see Windows Specifications.To the right of the heading version, you’ll see your version number and edition.
