Manually uninstalling the .NET Framework can be a bit risky, as it’s a complex process that requires careful attention to detail. If you’re not careful, you may end up deleting important files or registry entries that are required by other applications on your computer. This can lead to a range of problems, including application crashes, errors, and even system instability.
Furthermore, if you’re not sure what you’re doing, you may inadvertently delete files or registry entries that are required by the Windows operating system itself. This can lead to serious problems, including the inability to boot your computer or launch certain applications. To minimize the risks, it’s essential to follow a step-by-step guide and take careful backups of your system before attempting to uninstall the .NET Framework manually.
