next 10 tricks 4 Windows 8 users..10-20..

11. Mastering Internet Explorer in Windows 8

Click the Internet Explorer tile from the Start menu and you'll launch a full-screen version without toolbars, menus or sidebars, which like so much of Windows 8 may leave you initially feeling lost.

Right-click an empty part of the page or flick your finger down from the top of the screen, though, and you'll find options to create and switch between tabs, as well as a Refresh button, a 'Find' tool and the ability to pin an Internet shortcut to the Start page. Click the spanner icon and select 'View on the desktop' to open the full desktop version of Internet Explorer.

12. Run two apps side by side

Windows 8 apps are what Microsoft calls "immersive" applications, which basically means they run full-screen - but there is a way to view two at once. Swipe from the left and the last app you were using will turn into a thumbnail; drop this and one app displays in a sidebar pane while your current app takes the rest of the screen. And you can then swap these by swiping again.

13. Spell check

Windows 8 apps all have spellcheck where relevant, which looks and works much as it does in Microsoft Office. Make a mistake and a wavy red line will appear below the offending word; tap or right-click this to see suggested alternative words, or add the word to your own dictionary if you prefer.

14. Run as Administrator

Some programs need you to run them with Administrator rights before they'll work properly. The old context menu isn't available for a pinned Start screen app, but right-click one, and if it's appropriate for this app then you'll see a Run As Administrator option.

15. Make a large app tile smaller

You'll notice that some Windows 8 apps have small live tiles, while others have larger tiles that take up the space of two tiles. Right-clicking on a Windows 8 app's Start screen tile will display a few relevant options. If this is one of the larger tiles, choosing 'Smaller' will cut it down to half the size, freeing up some valuable Start screen real estate.

16. Uninstall easily

If you want to hide an unused app for now, select 'Unpin from Start'. The tile will disappear, but if you change your mind then you can always add it again later. (Search for the app, right-click it, select 'Pin to Start'.)

Or, if you're sure you'll never want to use an app again, choose 'Uninstall' to remove it entirely.

17. Apps and privacy

It is worth keeping in mind that by default Windows 8 apps can use your name, location and account picture. If you're not happy with that, it's easily changed. Press Win+I, click More PC Settings, select Privacy and click the relevant buttons to disable any details you'd rather not share.

18. Administrative tools

Experienced Windows users who spend much of their time in one advanced applet or another are often a little annoyed to see their favourite tools buried by Windows 8. Microsoft has paid at least some attention, though, and there is a way to bring some of them back.

Open the Charm bar by flicking your finger from the right-hand side of the screen and select 'Settings' then 'Tiles'. Change 'Show administrative tools' to 'Yes' and click back on an empty part of the Start screen. And it's as simple as that. Scroll to the right and you'll find a host of new tiles for various key applets - Performance Monitor, Event Viewer, Task Scheduler, Resource Monitor and more - ready to be accessed at a click.

19. Disable the lock screen

If you like your PC to boot just as fast as possible then the new Windows 8 lock screen may not appeal. Don't worry, though, if you'd like to ditch this then it only takes a moment.

Launch GPEdit.msc (the Local Group Policy Editor) and browse to Computer Configuration > Administrative Templates > Control Panel > Personalisation.

Double-click 'Do not display the lock screen', select Enabled and click OK.

Restart and the lock screen will have gone.

If you can't easily find GPEdit.msc by searching in the Start screen, search for 'mmc', and then press Enter. On the File menu, click 'Add/Remove Snap-in', then in the 'Add or Remove Snap-ins' dialog box, click 'Group Policy Object Editor', and then click 'Add'.

In the 'Select Group Policy Object' dialog box, click 'Browse'. Click 'This Computer' to edit the Local Group Policy object, or click 'Users' to edit Administrator, Non-Administrator, or per-user Local Group Policy objects, then click 'Finish'.

20. Install anything

Most mobile platforms recommend you only install apps from approved sources to protect your security, and Windows 8 is the same: it'll only allow you to install trusted (that is, digitally signed) apps from the Windows store.

If this proves a problem, though, and you're willing to take the security risk (because this isn't something to try unless you're entirely sure it's safe), then the system can be configured to run trusted apps from any source.

Launch GPEdit.msc (see above for instructions on how to find it), browse to Computer Configuration > Administrative Templates > Windows Components > App Package Deployment, double-click 'Allow all trusted apps to install' and select Enabled > OK.
