Why should I remove every two or three days for correct display of the icon cache icon in Win7?

The reason why I care about is, when I program an application with its own icon, is displayed another icon instead of the correct icon (apparently by a random selection of Windows 7). For example, the icon for Notepad, calc or MS Office Word, Excel, Powerpnt and so on... restart of the operating system function. And Windows shows wrong icon in the folder (or desktop) as "and" in the taskbar or in the window of the application.
Anyone know what this might be caused by?
In Win XP was not this problem and Microsoft cannot fix this in Win7, although the internet is full of it.
Any ideas how to solve this problem of user environment (where Microsoft is not able or is lazy to solve this problem by programming) for longer than two days (or three with a bit of luck) to give advice to users of my apps how to show once for all correct icons?
Because not all users of my application will rebuild icon cache (every two days) to detect the correct icon of my application.
Thanks for any advice and sorry for my bad English.

Hi Jose,

Method 1:

Important: this section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

For more information about how to back up the registry, see the link:

I suggest refer you to the article and try to run Microsoft fix:

Icons change incorrectly in Windows


Method 2:

Try to run Microsoft Safety Scanner for any spyware or malware infection.


Note: the Microsoft Safety Scanner expires 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again. The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

Let us know the results.
