Windows vista extreme lite10/30/2022 Windows vista extreme lite software#However, since you’ll be forced to run 32-bit apps on Vista 圆4 most of the time, you’ll be dependent on WoW64 as long as software vendors focus on Vista x86. The importance of Vista’s virtualization mechanisms for legacy apps decrease steadily because software vendors adapt their programs to Vista. However, any new complexity layer can be the cause of unforeseen problems. UAC and folder name changes made them necessary. WoW64 is comparable to the other virtualization mechanisms in Vista which assure software compatibility with Windows XP programs. For example, WoW64 redirects HKLM\Software to HKLM\Software\Wow6432Node. Hence, WoW64 has to redirect them to SysWow64. 32-bit apps always try to load system libraries from System32. Vista 圆4 stores 32-bit libraries in C:\Windows\SysWow64. However, despite of its name, it only contains 64-bit libraries. You’ll also find this folder on Vista 圆4. 32-bit programs are often dependent on 32-bit system libraries which are stored under C:\Windows\System32 on Vista x86. In my opinion, more problematic is the second feature of WoW64. Windows vista extreme lite install#If you install Vista x86 on a 64-bit CPU, it will always run in 32-bit mode. This doesn’t go at the cost of performance. It switches the CPU from 64-bit mode to compatibility mode when you launch a 32-bit app. Vista has to perform some acrobatics to make this possible. You should be aware of the fact, though, that running 32-bit apps on Vista 圆4 comes with a price. So all in all, I’d say application compatibility is not really an issue anymore. If you are unsure whether your Vista apps are 64-bit compatible, you can just test them with VMware Server or VMware Workstation. The only way to make them work on Vista 圆4 is to create your own installer package. Some older 32-bit programs have a 16-bit installer. Notice that 16-bit apps don’t work at all on Vista 圆4. If you know of such an application feel free to leave a note below. Actually, it is hard to find software that runs on Vista x86 but not on Vista 圆4. However, it is also a matter of fact that now most Vista compatible 32-bit apps work on Vista 圆4 as well. Their hooks go deep into the operating system which requires playing 64-bit. Manufacturers of antivirus software are a good example. Essentially, those software vendors offering 64-bit versions, do so only because they were unable to make their 32-bit editions work on Vista 圆4. That is, most Vista compatible applications are 32-bit. 64-bit applications ^Īccording to an article of the German print journal C’t (8/2008), 64-bit is still not a topic for most software vendors. In my next post, I will blog about Vista 圆4 hardware compatibility. Today, I will focus on software compatibility.
