由于不再支持.Net Framework 4,4.5和4.5.1，我需要手动禁用/卸载它们吗? [英] Since .Net framework 4,4.5 and 4.5.1 are not supported anymore do I need to manually disable/uninstall them?

问题描述

我有Windows 8.1(从8更新)，我使用Windows Update安装关键更新，并且没有手动安装/删除任何.Net框架.我从这里https://blogs.msdn.microsoft.com/astebner/2008/10/13/net-framework-setup-verification-tool-users-guide/使用验证工具进行了检查 并且成功验证了以下版本:

I have Windows 8.1 (updated from 8), I use windows updates to install critical updates and have not manually installed/removed any .Net frameworks. I checked with the verification tool from here https://blogs.msdn.microsoft.com/astebner/2008/10/13/net-framework-setup-verification-tool-users-guide/ and it succesfully verified the folowing versions:

.NET Framework 4客户端的安装状态:未安装任何Service Pack.
.NET Framework 4完整版的安装状态:未安装任何Service Pack.
.NET Framework 4.5的安装状态:未安装任何Service Pack.
.NET Framework 4.5.1的安装状态:未安装任何Service Pack.
.NET Framework 4.5.2的安装状态:未安装任何Service Pack.

Install state for .NET Framework 4 Client: installed with no service packs.
Install state for .NET Framework 4 Full: installed with no service packs.
Install state for .NET Framework 4.5: installed with no service packs.
Install state for .NET Framework 4.5.1: installed with no service packs.
Install state for .NET Framework 4.5.2: installed with no service packs.

定期从Windows Update获得4.5.2的安全更新，但是由于不再支持以前的更新，因此不再对此进行更新(自2016年1月对.NET Framework 4、4.5和4.5.1的支持终止-https ://blogs.msdn.microsoft.com/dotnet/2015/12/09/support-ending-for-the-net-framework-4-4-5-and-4-5-1/)

Regularily there are security updates for 4.5.2 from windows update but since there is no support for the previous ones anymore no update for those (Since Jan 2016 Support Ended for the .NET Framework 4, 4.5 and 4.5.1 - https://blogs.msdn.microsoft.com/dotnet/2015/12/09/support-ending-for-the-net-framework-4-4-5-and-4-5-1/)

为了安全起见，我是否必须手动禁用/取消保留它们?如果是的话，该怎么做?

Do I have to manually disable/unustall them in order to be safe? If so what are the steps to do for that?

您可以根据需要删除系统上的.NET Framework的旧版本，但需要注意的是.我建议您最好保留它们.

You can remove the old versions of .NET framework on your system if you wish, but doing so comes with caveats. I would suggest you had better keep them.

很可能您的系统上已经安装了一个程序，该程序需要特定版本的.NET Framework.如果删除错误的.NET Framework，则某些程序可能不再起作用.就是说，.NET框架的更新版本最有可能 与旧版本的.NET Framework不向后兼容.

Most likely you have a program already installed on your system that requires a specific version of .NET framework. If you remove the wrong .NET framework, some programs may no longer function. That said, newer versions of .NET framework are most likely not backwards compatible with older versions of .NET framework.

案例和要点:如果一个旧程序需要.NET Framework版本4.该程序的作者不知道存在最新版本的.NET Framework版本(当前为4.5.2版)，因为该程序不只是一个.NET Framework版本.十年之久，因为.NET 框架版本4是当时唯一可用的版本.因此，该程序在您的系统上安装期间特别要求.NET Framework版本4.因此，尽管从技术上讲，该特定程序不能与.NET Framework 4.5.2一起使用. 它可能是兼容的.

Case and point: if an old program requires .NET framework version 4. The author of the program did not know that the latest version of .NET framework version existed (currently version 4.5.2) because the program is more than a decade old, and because .NET framework version 4 was the only version available at the time. As such, this program specifically requests .NET framework version 4 during install on your system. Therefore, this particular program won't work with .NET framework 4.5.2, though technically it may be compatible.

如果您坚持只使用最新的.NET框架，则必须弄清楚哪些程序使用了旧的.NET框架，并使用提供类似功能和/或不需要.NET的较新程序来卸载/替换它们.框架 功能.

If you insist on only using the newest .NET framework, you will have to figure out which programs use the old .NET framework and uninstall / replace them with newer programs that provide similar functionality and / or that do not require .NET framework to function.
