Windows 7 Problem with Running 32 bit Applications on windows 7 64 bit

[Turetsky]

Hi everyone,
I just got a new OS windows 7 64 bit and when i run the 32 bit Applications they show blurred (when i look in the task manger the process shows *32) the 64 bit application run perfect . I read about that the OS windows 7 64 bit runs the 32 bit Applications with WOW64.
Do you know what makes the Application 32 bits show blurred ?? And how could i resovle it ??

Thanks for your help,
Eli

When running 32-bit applications on a 64-bit version of Windows like Windows 7, the operating system uses a compatibility layer called Windows on Windows 64 (WOW64) to run these applications. WOW64 allows 32-bit applications to run on a 64-bit Windows system seamlessly. The "blurred" effect you are experiencing with 32-bit applications on a 64-bit Windows 7 system is likely due to the way Windows handles these applications visually to distinguish them from 64-bit applications. Here are a few common reasons why this happens:

1. Visual Indication: Windows uses this visual cue to differentiate between 32-bit and 64-bit processes. When you see a process listed as *32 in Task Manager, it indicates that it's a 32-bit process running on a 64-bit system.
2. Compatibility Mode: When running in WOW64, 32-bit applications might not render as sharply as 64-bit applications due to the translation and emulation processes involved in running them on a 64-bit system. To improve the visual appearance of these 32-bit applications, you can try a few things:
3. Adjusting Display Settings: Sometimes adjusting the display settings can help with the blurriness. Right-click on the application's shortcut, go to Properties, and then navigate to the Compatibility tab. Here you can try adjusting settings related to display scaling.
4. High DPI Settings: Windows adjusts the scaling of the applications automatically. However, you can try overriding the High DPI scaling behavior for specific applications. To do this, right-click on the application's shortcut, go to Properties, then the Compatibility tab, and click on "Change high DPI settings."
5. Update Graphics Drivers: Ensure that your graphics drivers are up-to-date as outdated drivers can sometimes cause display issues with applications.
6. Check for Application Updates: Make sure the 32-bit applications themselves are updated to the latest versions. Sometimes updates include optimizations for newer operating systems. By trying these steps, you might be able to improve the appearance of 32-bit applications running in Windows 7 64-bit under WOW64 compatibility.
