Migrating to a new PC can be a lengthy and tedious business, especially if you have to manually find, download and install all the programs you had on your old system. RuckZuck is an open source package manager which helps you manage the process in a few clicks.

The program is portable, and surprisingly small -- a single 176KB executable -- although that’s partly because it uses PowerShell 4 to do most of the work.

Bitdefender Labs has released BDAntiRansomware, a free tool which keeps your PC safe from some of the most common ransomware threats.

The program "protects against known and possible future versions of the CTB-Locker, Locky and TeslaCrypt crypto ransomware families", the company explains.

We've talked about simple DWG/DXF viewers before -- de-caff,Mini CAD -- but while they're compact and easy to use, they won't open everything: CAD formats are just too complex.

If accuracy and reliability are key, then you might prefer Autodesk DWG TrueView 2017 -- it's from the people who developed the DWG format, so you can be sure it'll open just about anything.

Google is making its collection of image-editing plugins -- the Nik Collection -- available free of charge. Previously sold for $149, the Nik Collection came into Google's hands when it acquired Nik Software three years ago. If you recently shelled out on the plugins, you needn't feel like you're getting a bad deal; Google says that anyone who purchased the collection this year is eligible for a full refund.

Comprising seven plugins -- Analog Efex Pro, Color Efex Pro, Silver Efex Pro, Viveza, HDR Efex Pro, Sharpener Pro and Dfine -- Google says that the Nik Collection brings "powerful photo editing tools once only used by professionals to even more people".

There are many tools to help you customize a USB flash drive. You could make it bootable, run one or more LiveCDs, lock it to prevent unauthorized access, create encrypted storage areas, and more.

This will often work just as you expect, but sometimes, when you try to use the flash drive to store files again, you might find that some of its capacity has disappeared.

Freeware desktop capture and recorder tool oCam has been updated to version 254 with new mouse effects. It’s now possible to highlight left and right mouse clicks with various animations, making your actions much clearer to the viewer.

This is all very configurable, with five animation styles, your choice of color, size and duration, and a preview window to simulate the results.

If you think an application is suspicious, then you might run it in a sandbox, a virtual machine, maybe use a debugger, and watch what it does. And if nothing happens then that means it’s safe. Right?

Well, maybe not. Malware will often try to detect this kind of trickery, and if it thinks it’s being watched, won’t do anything to raise an alarm.

Windows snapping can be a convenient way to reorganize your desktop: just drag and drop a window to the left of the screen, for instance, and it automatically resizes to fill the left half of the display.

Not everyone is a fan. There are only a few snapping features. Some people find they’re easily launched by accident. And apart from turning them off, there’s no real configuration available at all.

Root certificates are a cornerstone of web security, a vital element in ensuring the sites you visit are who they claim to be.

Windows ships with a lengthy list of known trusted certificates, but applications -- and malware -- can add more, and there’s no easy way to tell which are legitimate, and which might be a problem.
