Too bad that April Rollup again didn't work for Efdy and it probably won't work for me.
Let me supply two pieces of information.
1. I saw the following messages in c:\windows\logs\cbs.log :
==================================================================
2018-04-07 00:20:31, Info CBS SQM: Failed to start upload with file pattern: C:\Windows\servicing\sqm\*_std.sqm, flags: 0x2 [HRESULT = 0x80004005 - E_FAIL]

=====================================================================
Googling a bit, people did seem to need to reinstall/repair Windows 7 before this problem can be fixed.

Somebody here :
https://social.technet.microsoft.co...ils-with-error-0800f0826?forum=w7itproinstall
said that he solved the problem : " .... I had to take ownership and reset permissions on about 100 different reg subkeys of HKLM\System\CurrentControlSet\Enum\Root .... "
I almost wanted to do the other day. But the above message was ~2011 and so I hesitated a bit.
Any comments ??
