From Microsoft:

Although OEMs have been shipping hardware virtualization in PCs for three years, hardware virtualization is not available in all PCs — so even if your PC is new, it may not have hardware virtualization. Additionally, those PCs with hardware virtualization have it turned off by default, so you will need to turn on the hardware virtualization capability before you can use it.

A download tool is available to test your processor for both Intel and AMD. Please see Microsoft’s site for download links.

Many of you held off upgrading from XP to Vista are considering the upgrade to Microsoft’s latest operating system Windows 7, but are wondering if many of your existing applications such as WinFax PRO will work.

WinFax PRO and TalkWorks PRO (the fax/voice version of Symantec’s popular fax software) still have a strong user base and many of you don’t want to give up this powerful and easy to use desktop faxing software.

Unfortunately, Windows 7, doesn’t change the compatibility issues with WinFax PRO that were introduced with Microsoft Vista.  As expected, the same compatibility issues with WinFax PRO and TalkWorks PRO also exist with Windows 7.

We ran the Windows 7 Upgrade Adviser, this is a tool offered by Microsoft that scans your computer to determine if it can be upgraded to Windows 7. The program also scans all the existing software installed, and determines if there are any known compatibility problems with Windows 7.  The Windows 7 Upgrade Adviser, incorrectly  indicates that WinFax PRO / TalkWorks PRO has some minor issues, and to contact the publisher’s web site. . The link to Symantec’s Web site is no help as Symantec chooses to ignore the existence of WinFax or TalkWorks since they’ve discontinued the software.

Minor issues they are not. You may be able to install WinFax or TalkWorks with Windows 7, but the required WinFax printer driver will not install.  This will prevent you from accessing WinFax from any application you want to fax from, it also prevents you from adding attachmentssuch as PDFs, Word documents, Text files, images, etc. for faxing.

Windows 7  Professional and Ultimate will include the not so impressive fax utility called Windows Fax & Scan, a feature that was previously included in the Vista Ultimate and Vista Business Editions. If you’d rather update your software to a much more professional package that is compatible with both 32 and 64 bit versions of Windows 7, Vista, Windows Server 2003 & 2008, Windows XP and 2000, then we recommend FaxTalk FaxCenter Pro 8 or FaxTalk Messenger Pro 8.  For more details, see our Web page at http://www.getfaxing.com/faxtalk

Windows 7 is not compatible  with WinFax PRO. There is no upgrade path available from Symantec for Windows 7 compatibility.  The WinFax PRO 10 software was discontinued by Symantec in June 2006, and no plans for future versions exist.   For information on moving to another software package that can import your WinFax data, please see http://www.getfaxing.com/faxtalk

If you’ve recently upgraded to Microsoft Vista, or purchased a PC with Vista pre-installed and want to use WinFax, you’re out of luck.  WinFax PRO will install under Microsoft Vista if you bypass the install warning message about compatibility, but it will not operate properly. The WinFax printer drivers will not install in Vista (it’s not compatible with the operating system due to Vista’s blocking of Kernel Mode printer drivers). The printer driver is the heart of WinFax, without it, you can’t send (“print”) faxes from your Windows applications, or can you attach documents. There are also several other incompatibilities that I have encountered, such as Fax Sharing (probably due to IPv6), and some application crashes/shutdowns when clicking on fields that happen to require number (digit) entry (usually these are within phonebooks, IP address, area codes, etc.). This is a known problem to occur after upgrading to Internet Explorer 7 or Service Pack 2 or 3 under Windows XP, this issue has been identified and resolved. I have not found any solution for this under Microsoft Vista.
