Why a donation is required to become a registered user ? Isn't this more actually a sale ?

Because I receive few donations, I (the developer) can't operate like a real business that sells products. To operate like a real business that sells products I will have to pay more taxes over a year than the donations I receive. Your donation is used to buy software licenses, new hardware, hosting costs for the website. You support the project with your donation and as a reward for your gratitude you receive a lifetime license for all the computers that you own. There is one time donation and you will be a registered user for all versions of all programs from this website. I think this is a fair deal.

Why your programs are not signed with a digital signature ?

A code signing certificate from a trusted certificate authority costs some hundreds of US dollars a year. Since I receive very few donations, this is not a priority. On each product page, the SHA256 hash of the installer is published so that a user can verify if the installer is the official one.

I want to make a donation and become a registered user. What is My account area ? What is there ?

When you become a registered user, you receive an automated email with your credentials that will give you unlimited access to My account area. From your registered user account you have access to an online activation code generator. You can access your account from anywhere and get a new activation code anytime you want. For example, you have reinstalled your operating system, or you have bought a new computer. Your login credentials are automatically sent to you by the donation script.

I am a registered user but I forgot my username/my password. How can I recover my account ?

If you forgot your password, you can reset your password through the recovery page. If you forgot your username, please send me an email and I will resend your login credentials to access your registered user account. In order to identify you in the registered users database, please provide me your full name and the email address that you have used with PayPal when you became a registered user. Usually, your username is your primary email that you have defined in your PayPal account.

The memory usage seems to be a bit high. It may be possible that you have a memory leak in your software ?

Windows Firewall Control and USB Flash Drives Control use .NET Framework. These applications tend to have a larger memory footprint than native unmanaged applications. This is because the framework loads any required assemblies into memory. The memory usage reported by Task Manager is not very accurate because from these loaded .NET assemblies, some of them might be shared between multiple applications, but in Windows they appear and are counted for each application separately. For a .NET application the memory consumption is very standard. This is not so important. CPU usage is important because it can slow down the computer. One thing is sure: you will not run out of memory while using these products.
