Sadly we can’t feature every new and updated application, but that doesn’t mean that some of the apps we haven’t covered aren’t worth rounding up. There are a number of interesting applications that are worth some investigation and we’ve rounded up some of these apps put live during the last week.

doPDF 7.2.363 is a powerful free tool you can use to produce a PDF from just about any Windows application. Instead of sending it to your printer, simply print to the doPDF device. Creating a PDF is the ideal way of distributing a document for download, by email or for commercial printing. Just about any printer will take a PDF as your master.

If you regularly switch between screen resolutions (for example, using your laptop and then connecting to an external monitor), then you’ll also know it’s a real pain when desktop icons are automatically re-positioned to fit the smaller resolution. DesktopOK 2.51 is a simple tool which enables you to pre-program your desktop layout for each screen resolution. No manual re-positioning required. There’s also a 64-bit version.

After Adobe announced Creative Suite 5.5, individual applications were also updated, including Adobe Dreamweaver CS5.5, Adobe Flash Professional CS5.5 and Adobe InDesign CS5.5. Updated to enable you to design content for an iPad and similar devices.

Sysinternals Suite 2011.05 is a comprehensive collection or all the Sysinternals applications whilst one of these apps, Process Explorer 14.11, is a more advanced Task Manager replacement. If you’re keen to view the latest web browser developers, Google Chrome Canary 13.0.754.0 will give you the latest pre-developer build almost every single day. Use with caution though. Opera “Next” v11.50 is the Opera equivalent. Since when did developers encourage users to test alpha versions? Firefox 5 Beta 1 is due on May 17th.

Kaspersky TDSSKiller 2.5.0.0 was updated this week and is a popular free tool that will enable you to detect and remote an installed rootkit. Complements your existing security software. Talking of security software, Comodo Internet Security 5.4 was updated this week, along with Comodo Firewall 5.4 and Comodo Antivirus 5.4. SUPERAntiSpyware 4.52 Free was updated, whilst we wait for the final release of v5, due soon.

Notepad2 4.1.25 is a more powerful version of Notepad with automatic syntax highlighting and much more. There’s also a 64-bit edition. We also recommend XnConvert 1.02 (32-bit) and XnConvert 1.02 (64-bit) which will handle and process multiple images.
