Internet Explorer automatically updates. https://www.google.com/chrome

FYI: "Andrew..." is right; and more significant, Chrome (and soon Firefox) will be pushing out updates whether you want them or not. Usually these are security related, but it always seems to me it's a case of "change for the sake of change"...and not always convenient or anything astonishingly great in the GUI. Commercial Operating Systems are slowly becoming the property of everyone but yourself, 'good guys' or 'bad guys', IMHO. This auto update aspect and the relentless threat of catastrophic meltdown with Windows is another reason to back up data on a regular timetable. Better get something in the works, 'cause it's inevitable you'll need one. Backing up data, using any utility, will depend a lot on whether or not you use the Windows DEFAULT for documents, photos and so on. If your 3rd party application "saves" to a different location (like the desktop for instance*), you must be sure to copy those separately, or they will be lost. Windows has a backup built in (System Tools> Backup), but I find it bulky & hard to use. *The desktop items are essentially a singular folder. Backups should be the 'all' data option as a baseline; after that use the 'incremental', which saves only new items, and changes to originals. This saves space on your backup media. Ideally 2 copies are made of each backup: one kept with the unit, one kept 'off site' in case of fire, tornadoes, floods, etc. One decent B.U. application is 'Cobain' (moderately easy to use; freeware). http://www.educ.umu.se/~cobian/cobianbackup.htm And most important: don't use iE if there's any way at all to avoid it. It is NFG. Get Firefox as your default browser & use it for everyday tasks. The following mods help, but methods ("vectors") are dynamic, and users must stay abreast of daily threats.

Chrome, although blazingly fast, has the nagging problem of Google snooping, which I find more annoying and threatening than any speed difference among the leading browsers. It also must be modified from the 'stock' in order to confine what's being fetched.
