    I maintain a Windows 7 Home Premium laptop for a friend. It is used primarily for storage (photos etc.) but occasionally a family member does go online with it so I would like to keep it as up to date as possible. It has 0Patch and is currently updated through the April 2022 Windows ESU updates, but it has .NET framework 4.5.2, which has now received its last update. I’m not sure how best to proceed.

    The laptop appears to have come with .NET 4.5.2 installed, so I don’t have any idea what programs or apps might need it. I gather that it’s not a good idea to just uninstall it, if that’s even possible. So I imagine I need to update to a later version to avoid a security risk going forward, is that right? .NET is such a pain.

    Long ago I hid KB4503548, the Microsoft .NET Framework 4.8 for Windows 7 x64, since at the time it came out it didn’t seem to work well with Windows 7, or at least the advice on AskWoody was to wait. Well it’s still waiting. I see that some Windows 7 users here on AskWoody successfully run .NET 4.8 on their machines. Should I try installing the update by unhiding it and then hope that Windows Update offers the necessary updates through Win7 EOS, and then install the more recent ones as I have with the other Windows updates? Am I likely to run into problems installing that KB4503548 since it is so old? Are there other pitfalls that I’m likely to encounter?

    I see that “.NET Framework 4.7.2 Runtime” is available to download from the dotnet site. Would it make sense to download and install it instead of 4.8, since 4.7 works well on my own Windows 7 laptop? Then I might have to go through this all over again when 4.7 reaches end of support, but I can’t seem to find an EOS date for version 4.7. Maybe it would be after we no longer allow Windows 7 to go online.

    I do have a current Macrium Reflect image of the laptop to fall back on in case things don’t go well, but I’m just trying to find a path that is least likely to cause problems. I would welcome any advice on how to avoid or minimize problems.

      The easiest way would be to unhide the installer for .NET Framework 4.8 and use Windows Update to install it.

      Otherwise, download the .NET 4,8 installer from Microsoft Catalog and dotNetFx4_ESU_Installer_r.zip from here and use the method described to install

      https://www.askwoody.com/forums/topic/standalone-installer-script-for-windows-7-esu-regardless-the-license/.

      Once it’s installed, you will need to update it. Run the latest .NET 4.8 Rollup listed at the bottom of the above thread linked above.

        Thanks, I’ll try unhiding the installer and then use the standalone installer to update. I’ll let you know how it goes!

      Everything seems to have gone well with the installation and update. I unhid the 4.8 installer KB4503548 and Windows Update installed it without any problem. It did take about 15 minutes to install.

      After the restart, I let things run for about 45 minutes until Trusted Installer calmed down and then used the dotNETFx4_ESU_Installer_r to install the April 2022 4.8 update KB5012125. Again, there were no problems and it took about 8 minutes. Installed Updates shows both KB5012125 and KB4503575 installed as of today.

      Everything seems to be working well. Thanks once again for your advice and reassurance!
