In one sentence, describe what the following article is about: When it comes to maintaining tile, the best solution is prevention. By sweeping, vacuuming and polishing your flooring on a consistent basis, there will be less chance of stain-causing substances accumulating underfoot. Be on the lookout for places where dirt and debris have a tendency to collect, especially in corners, beneath furniture and around the baseboards. Aim to sweep or vacuum your tile floors every couple of days, and to mop or give them a more extensive wipedown about once a week. Neglected tile will quickly begin to advertise itself. If you allow it to get bad enough, it may even negatively affect the value of your home. When left untreated, even the smallest spill can become a stubborn stain. As promptly as possible, blot the affected area with a clean cloth dampened with warm water or a small amount of vinegar solution. Tracked-in dirt and food particles should be swept up so they don't get ground into grout or rough surfaces. Gradually apply more vinegar as need until the stain begins to come out. Responding to messes quickly is especially important if you have light-colored tile or grout that make discoloration more noticeable. Tile is praised for its durability and ease of cleaning, but it's not indestructible. Harsh chemicals like bleach can cause natural materials to fade, while astringent cleaners may ruin the smooth finish of porcelain tiles after only a few uses. Whenever possible, opt for mild green alternatives such as vinegar and baking soda instead. Even commercial tile cleaners can take their toll when used frequently, and are usually no more effective than garden variety vinegar, anyway. Never use anything more abrasive than a stiff-bristled brush or kitchen sponge to scrub your tile floors. Doing so may leave behind small scratches in which dirt and mildew can set up for good.
Summary: Clean tile floors regularly. Wipe up spills and messes right away. Avoid using chemical cleaners.

In one sentence, describe what the following article is about: If you're merely trying to install a new version of Windows on your existing computer, skip this step. Insert the USB flash drive into a USB port on the computer.

If the computer turns on when you open its lid or move the mouse, you'll still need to restart it before proceeding. As soon as the computer's startup screen appears (the screen right after the computer shuts down and is beginning to restart), begin pressing the BIOS key. Your computer's BIOS key will vary depending on the manufacturer, but it will usually be one of the function keys (e.g., F2), Esc, or Del. You can check your computer's BIOS key online or in the manual that came with your computer. Many computers will flash a "Press [key] to enter setup" (or similar) message at the bottom of the screen as your computer is starting up. This is the key that you should press. If you miss your opportunity and the computer finishes the restart cycle, you'll need to restart it and try again. This section is usually in the Advanced or Advanced Options tab, but each BIOS menu is different. The "Boot Order" section will have a list of different startup locations, including your hard drive's name and your CD drive. Using the arrow keys, move the highlight bar down until it's covering the flash drive's name. On some computers, you'll instead select Removable Storage or Removable Drives (or something similarly titled). You'll usually do this by pressing the + key until the flash drive is at the top, but check the legend at the bottom or on the side of the BIOS screen to see if your controls are different. There's usually a key that you can press to do this, so check the legend to see what it is and then press it. You may have to press another key to confirm this decision. If your computer doesn't greet you with a "Press any key" screen and instead finishes the restart cycle, restart it again to boot from the flash drive. This will launch the Windows setup process.
Summary:
Go to the computer on which you want to install Windows. Plug in your USB flash drive. Prompt the computer to restart. Rapidly press the computer's BIOS key. Find the "Boot Order" section. Select your flash drive's name. Move the flash drive to the top of the list. Save your changes and exit the BIOS. Restart your computer again if necessary.
