Hello Michelle,
- I ran OffCAT 2.2 on both,
a) my active/updated HDD and b) my clone HDD (cloned on 24. October).
Result/conclusion:
I think OffCAT is not able/cannot help to identify the root cause of our problem
(because in my last/changed understanding the problem is not Excel/Office, but rather Windows 10)
Details:
Numerically my OffCAT scan results on Excel 2013 are
a) active/updated HDD: Critical= 1, Warning= 2, Informal= 5
b) cloned HDD
: Critical= 2, Warning= 2, Informal= 4
1+2+4=7 messages are identical, which include both, the critical and warning message Peter got and 2 out of the 3 informal messages KimAlbright got (by "fix-it" I succeeded
to remove one of the two warning messages, but found no impact on "scroll inactive window", corresponding to the not related warning description, as possible time delay because some logging was set active).
The cloned HDD reported in addition as critical, that Office is not at the latest status. After 24.Oct I found only KB3200802 was released by 8.Nov which naturally is
not included in my clone, but 8.Nov is clearly several days after the problem started (8.Nov as the only Office/Excel update does not coincide with the occurrence of our problem this means Office/Excel cannot be the root cause).
Surprisingly only the active/updated HDD reports informally, that 1 Windows update is not yet installed, whereas the cloned HDD, having clearly not up to date Windows
status 24.Oct, did not give such message.
In above 2 differences I cannot see any relation to "scroll inactive window" and also the Office update timing is not matching which is why I concluded OffCAT is not
able to identify the root cause of our problem (the root cause must be Windows 10).
- To understand the situation you are seeing it would be nice you can give us some basic feedback as:
- How many Windows 10 PC with Excel 2010/2013/2016 have you checked?
- On how many could you confirm our problem?
- On Google search "scroll inactive window, Excel" I found that exactly our problem was encountered by MAC users with ‘Office for Mac 2011’ and their different operating
system already beginning 2014.

I understand MAC users could scroll an inactive window with Word, but not with Excel. The only difference MAC <==> Windows seems to be, that for Windows 10 users
"scroll inactive window"was
working initially whereas for MAC users it seem not to have worked from the beginning.
- When MAC users see basically the same characteristic I conclude, there must be a very basic difference between Word and Excel in their interaction with the operating
system (Windows 10 or MacOS). As Peter has claimed I now think my previous statement
"automatic Excel update that causes the blocking" is wrong/misleading.
Checking details on KB3197954 I found:
a) It got installed on my PC 28.Oct, which time wise coincides with the occurrence of the problem/non-ability to scroll inactive window around Excel
==> as others stated/confirmed by deactivating also I think root cause of problem is KB3197954
b) Microsoft describes KB3197954 as a Windows 10 update
c) A search for the word "Excel" in Microsoft’s huge info file on KB3197954 found no match at all
Seeing today all above points I think the problem root cause is not Excel by itself, but rather an interaction between Excel 2010/13/16 and Windows 10. Such interaction
can be disturbed from both sides, Excel and/or Windows. In our case it looks like the root cause is Windows 10, because only Windows changes match time wise the disappearance of "scroll inactive window" around Excel.
- Trying to analyze/understand further, in my image Windows 10 would need 2 basic functions to realize the "scroll inactive window" functionality.
a) Windows 10 must recognize on which window the mouse sits/points
b) Windows 10 must allocate the mouse scroll orders to the correct window
When Excel is the active window it is not possible to recognize any difference between both. The behavior, always the active Excel chart gets scrolled, can be explained
by a) Windows recognizes/sees the Excel window on the complete screen as well as by b) Windows always allocates the mouse scroll orders to the Excel window.
When, however, Excel is the inactive window one can clearly see that Windows correctly recognizes the window on which the mouse is (the scroll on any other active/inactive
windows stops when the mouse leaves that window/enters the Excel window).
==> I see a high chance KB3197954 has corrupted the way Windows allocates the mouse scroll signals to an Excel window (I believe Microsoft did something
special to avoid the problem MAC users already saw 2014, but KB3197954 obviously removed/deactivated Microsoft’s previous special effort)
Summary/Conclusion:
As users we can describe what and how it changed, for which I think now many points have been given. To proceed further I think it is necessary to understand in detail
how Microsoft technically realized the Windows 10 functionality "scroll inactive window" and this can be done only by Microsoft.
As I consider disappearance of "scroll inactive window" around Excel a problem/worsening the way I am working daily I am ready to do additional effort, but this requires
also some feedback (my point 2) and progress (OffCAT was a trial, but according my last/revised understanding OffCAT cannot help/succeed, because problem is rather Windows).
