6 last more common windows 7 problem (at last 22)

18. Can't disable hibernation

Windows 7 doesn't make it easy to turn off hibernation, annoying if you never use it as you'll permanently have a "hiberfil.sys" file taking up a sizeable portion of your hard drive. To rectify this situation, launch REGEDIT, browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power, and set HibernateEnabled to zero.

19. Poor video quality

The new Windows 7 power plan settings affect more of your software than ever before. If you notice video playback quality seems poor, for instance, then click Start, type Power Options and click the Power Options link. Click Change Plan Settings for your currently selected plan, click Change Advanced Settings, expand the Multimedia Settings section and make sure "Playing video" is set to "Optimise performance".

Alternatively, if you often play video on a laptop, then change the new setting to "Optimise performance" and you may see an improvement in battery life.

20. Where's Software Explorer?

If you've ever played with Windows Defender on Vista then you'll have probably noticed the Software Explorer feature, a very useful way to find out and control exactly what's launched on your PC when Windows starts. So it's a little annoying to see this has disappeared in the latest version, leaving you with only the aging MSCONFIG to control your startup programs.

We'd recommend you download and use Autoruns, then, instead. It's rather more technical than Software Explorer, but nothing else provides quite as much useful detail on the add-ons and extensions you'll be loading when Windows, Explorer and your browser are launched.

START UP: Autoruns shows all the programs that will load when your PC starts

21. Explorer navigation

The Windows 7 version of Explorer has partly disconnected its two panes, so if you're double-clicking your way down a complex set of folders in the right-hand pane, the left hand tree won't always expand to follow you.

This may improve performance a little, but it also means that you won't always be able to see the complete folder structure unless you expand it manually, which on balance seems a bad idea. If you agree then click Organize > Folder and Search Options, check "Automatically expand to current folder", and click OK to restore normal operations.

22. Windows Live Messenger and the system tray

Close Windows Live Messenger on Windows 7 and it'll display its icon on the taskbar, chewing up useful application space, rather than in the system tray where many believe it belongs.

Fortunately there's a very quick fix: right-click the shortcut to Windows Live Messenger, click Properties > Compatibility, check "Run this program in compatibility mode for" and choose "Windows XP (Service Pack 3)" from the list. Close Messenger and its icon should now appear in the system tray, just as you'd expect.
