## Technical notes

Built with C# and WPF for the modern version, C# and WinForms for the legacy version. Installers are made with Inno Setup 6 for modern and Windows 7/8.1, Inno Setup 5 for XP and Vista. The .NET build command is `dotnet publish windows-10-11/source/src/MemCleaner/MemCleaner.csproj -c Release -o publish`. The legacy build command is `dotnet build windows-xp/source/MemCleanerLegacy/MemCleanerLegacy.csproj -c Release`.

MemCleaner is not a registry cleaner, does not delete temporary files, ships no driver and makes no kernel patches. It is not a fix for a machine that is genuinely short on RAM.
