I have a phrase I often use with technology: Keep the children on the playground the same age. This means not mixing older and younger groups; they have different skill levels and abilities. The same goes for .NET 4.7, applications and Windows 7. If you dig into various locations on the web you will see post install side effects such as the following:
- Impacting Autocad and earlier versions as noted in a forum
- .NET 4.7 crashing Quickbooks as noted on a blog
- Possible issues with Arcgis Pro
- May have issues with touchscreen inputs as notes in this post
- Techsmith Snagit impact with .NET 4.7 as noted in this forum
I’ll be investigating and see if the 4.7 update is the trigger for these issues but in the meantime if you are impacted and want to block .NET 4.7 you can use a registry key as noted on the Ghacks site.
- Tap on the Windows-key, type regedit.exe, and hit the Enter-key on the keyboard. This should start the Windows Registry Editor.
- Go to the key: HKEY_LOCAL_MACHINE\Software\Microsoft\NET Framework Setup\NDP
- Right-click on NDP and select New > Key.
- Name that key WU.
- Right-click on WU, and select New > Dword (32-bit) Value.
- Name it BlockNetFramework47.
- Set its value to 1 (double-click it to set value).
What to do: Consider blocking .NET 4.7 on older operating systems.
Windows 10 1607 Side Effects
The release of 4034658 to Windows 10, version 1607 release had a few noticeable side effects: Naming it wiped out your update history. As an alternative, to see which quality updates have been applied, you can navigate to the inventory by going to Control Panel -> Programs -> “View Installed Updates.” In addition, the update had additional side effects of making any hidden updates pop back up again. So if you hid the 1703 update it will offer back up again. Finally in a network setting, WSUS servers will exhibit increased CPU, memory, and network utilization when Windows Update clients perform their first scan after installing KB4034658.
Remember this only happens with the KB4034658 for Windows 10 1607 update.
