It can be useful to protect an Excel spreadsheet with a password, for example before sending it by e-mail. Password-protected files are also encrypted, so there’s no way of seeing their contents without knowing the password.
You can do the same with Word documents. The process is virtually identical to that described below for Excel. Access databases can also be password protected, although it’s a little more complicated (look for File | Info | Encrypt with Password).
A web browser is the program you use on a PC, Mac, or smartphone to look at web pages. Web pages can be simple pages (like this one) or can be a way of searching the Web (like the search pages of Google or Bing) or one way of checking your e-mail such as Gmail (although there are other ways).
There are a number of ways, but one of the easiest, and one that works on all modern versions of Windows is this:
In details: hold down the Windows key, press and release the “R” key, let go of the Windows key.
The “Run box” will appear:
Type “winver” (without the quotes) and click “OK”.
You’ll be shown a box that tells you which Windows you have (Windows XP, Windows Vista, Windows 8, Windows 10), and, in smaller letters the version and edition – version 1610 of Windows 10 Pro, for example. Click “OK” to make the box go away.
Windows 10 was released in July 2015, with the offer of free upgrade for Windows 7 and Windows 8.1 home users (there is no Windows 9). My advice at the time to most of my customers was to wait and see how Windows 10 worked out, and not to rush into the upgrade. Sure enough, there was a major re-release of Windows 10 in November 2015 (the “Fall upgrade” or the “1511 upgrade”).
I’ve often mentioned that everyone should be cautious about downloading things from the Internet, especially things that offer to “clean the registry”, “check for out-of-date drivers” or “optimize your PC” and so on. Most (all?) of these are trick to get you to download some malware.
If you’ve been offered the free Windows 10 upgrade (most home users of Windows 7 and Windows 8.1 have been) my advice is to accept the download, but wait for a while before you allow it to perform the actual Windows 10 upgrade (it will ask you for permission).
My first impressions of Windows 10 are quite good – it’s certainly better than Windows 8 was – but there’s no rush. You have a year to accept the free offer, and it will be a big change in what you are used to (especially in the case of Windows 7 users) so wait for a while and see how everyone else gets on!
For those who have already done the upgrade, I’d advise turning off the new search bar which, by default, send everything to Microsoft. Instructions here.
