If your network isn’t running smoothly then Windows provides a lengthy list of tools which might be able to help. Unfortunately you’ll need to find them, first, and they’re so scattered around -- a console application here, a deeply nested Control Panel dialog there -- that even experts might find that takes a while.

NetAdapter Repair All in One tries to simplify this by providing easy access to a stack of network details and functions from a single straightforward interface.

Popular PC tools developer Wise Cleaner has released a public beta of its latest utility, Wise System Monitor.

The new addition is a desktop gadget which tracks and displays CPU usage, upload and download speeds, RAM consumption, CPU temperature and more.

Farstone Technology has released VirtualXP Free 1.0, a free-for-personal-use tool that simplifies the task of converting a Windows XP or Windows Server 2003 physical PC into a virtual machine.

The idea is that users hesitating about switching to a newer version of Windows can take their old system with them, ensuring all data, settings and programs continue to work going forward.

When you’re working at the Windows command line it might sometimes be useful to download a file, but the standard tools don’t make this particularly easy.

If you’re looking for something simpler then Curly could be ideal. It’s a console-based downloader, free, portable and amazingly small (under 28KB), yet somehow it still manages to squeeze in one or two surprising extras.

Take a picture with a digital camera and it’ll normally be tagged with the date and time, often useful later when searching or organizing your images.

If the camera clock is wrong, though, all your photos will have the wrong EXIF time stamp, and they’ll stay that way until someone notices.

Some music players are smart. Not only will they play your tracks, but they'll try to tell you more about them, perhaps downloading and displaying the lyrics.

Windows Media Player and iTunes aren't quite so clever, but that's where Song Buddy comes in. This free app for Windows, iPhone, iPad and Mac detects the "now playing" artist and displays other releases, concerts, images, a biography, links and more.

Mozilla has released Firefox 32.0 FINAL for desktop, with Firefox for Android 32.0 due to follow.

While there are a lot of changes to both desktop and mobile builds, Firefox 32 doesn’t throw up any standout new features, instead concentrating on tweaks and minor improvements.

High resolution digital photos are great for most purposes, but can be a little cruel for portrait shots, where every skin imperfection is suddenly blown up in extreme detail.

Some photo editors have "beautifying" modules to help clean such problems, or you can often fix them yourself with a little painting or clone work. Free Photo Blemish Remover is another option, a specialist tool which can remove image imperfections with a click.

If your PC has several user accounts then you might occasionally like to know when they're being accessed, perhaps to confirm that your children are only using the computer at particular times.

You could install some heavy duty system monitoring package, or maybe enable a few Family Safety restrictions for that account. But NirSoft's WinLogOnView is a much simpler option which could provide everything you need in a tiny, portable package.

Earlier this year we looked at Voralent’s JPGMini and PNGMini, easy-to-use tools which reduced JPG and PNG file sizes without affecting image quality.

The developer has now released a replacement, Antelope, which handles JPG and PNG files, and supports both lossless and lossy compression.

Google has updated its Chrome Beta channel with the release of Google Chrome 38.0 Beta. The new release, also available as Google Chrome 38.0 Beta (64-bit) for Windows and Linux, has two major highlights.

The first is an improved -- and more visible -- way of managing and switching between multiple Chrome user profiles, while the other sees 64-bit support extended to the OS X platform.

Discovering your external IP address is generally very easy. Just visit a site like WhatIsMyIP and it'll give you the IP address, location, ISP, and a whole lot more.

If you need speedy access to this address all the time, though, it might be simpler to use Mr.IP, a tiny free tool which permanently displays your internet -- or external -- IP on the desktop.

DXF is a very popular CAD file format which has been around since 1982, so you might expect there to be plenty of good viewers around by now.

Unfortunately, the reality is very different. DXF can be complex, and while there are free viewers to be found, they're generally of not much use.

Whether you're concerned about security, or just hoping to optimize your PC’s performance, understanding what's accessing your internet connection can be very helpful.

Network monitors will tell you more, but they're often targeted at experts, weighed down with complex details which -- even if you understand them entirely -- you may not really need. GlassWire is an interesting free network monitor aimed at a more general audience. It’s easy to use, looks great and provides in-depth reports, but they’re easy to follow and focus on only the most important information.

Resizing and repositioning windows on the PC desktop is such a fundamental task that you’ll almost do it without thinking. Move the mouse to the title bar/ border, click, drag, release. Very basic, very simple -- but there might still be room for improvement.

KDE Mover-Sizer is an open source, portable tool which brings a common Linux desktop trick to Windows. Instead of having to move your mouse cursor to the title bar or border, you just hold down the Alt key, then left-click anywhere inside a window and drag to move it, right-click and drag to resize it.
