Patch reliability is unclear. Unless you have an immediate, pressing need to install a specific patch, don't do it. |
Today we got preview updates for 2004: https://devblogs.microsoft.com/dotnet/net-framework-july-2020-cumulative-update-preview-for-windows-10-version-

I saw the same message. Quite odd considering they don’t even make it that hard to install a feature update.
KB4562899 Cumulative Update Preview for .NET Framework 3.5 and 4.8 for Windows 10 Version 2004 for x64 is installed, no hiccups so far.
IMO there something wrong with how the .NET preview KB4562900 is coded.
Previews should be optional, i.e. with BrowseOnly=True. But this one has BrowseOnly=False, meaning that when you seek for updates on Win10 1909, the Preview gets installed:
Is there some way to tell Microsoft to fix this? In the meantime, the only safeguard I can think of is to use wushowhide to hide it.
Here are the details from my PowerShell script:

First of all, the new .NET CU Preview is nothing different from all previous non-security .NET CU
it just has the term “Preview” in label
in my understanding, BrowseOnly attribute has no effect on Windows 10, thus not used
if you compare the attributes of .NET CU Security vs non-Security you notice this difference
.NET CU Security
AutoSelectOnWebSites : True (automatically selected by Windows Update as important update)
AutoSelection : 0
AutoDownload : 0
.NET CU non-Security (Preview)
AutoSelectOnWebSites : False
AutoSelection : 1
AutoDownload : 2
this is the visible difference
there are also another hidden difference related to Interactive configuration in the search criteria, which
in the case of Interactive scan (i.e. Seeker):
.NET Preview CU will be offered and installed regardless
in the case of non-Interactive scan (i.e. scheduled scan):
– if .NET Security CU is not yet installed, .NET Preview CU will be flagged as potentially superseded, and WU will not offer it
– if .NET Security CU is already installed, .NET Preview CU will be offered and installed
p.s. how did you managed to insert the details here as block code? 🙂
for me it won’t work and get the code in one line
Windows 10 1909 Pro July updates.
