Editor's Corner

Microsoft's process for providing software updates for its Windows and Windows Server platforms has evolved considerably over the years to the point where many of us today have difficulty understanding the updating process because of its complexity. Those of you who learned programming many years ago will be familiar with a tool that was frequently used in the early days of computing to explain the logic behind a program. Yes I'm talking about the flowchart.

It's been years since I've had to resort to flowcharting anything -- I think the last time I made one was to refresh my understanding of how DNS lookups work. I've often thought that creating a flowchart to describe how Windows Update works might be useful, but I've balked at the time it might take to research the subject in detail.

Fortunately some others have now done some work in this area. Jason Morris, Ingolf Becker and Simon Parkin of University College London have recently written a paper called In Control with no Control: Perceptions and Reality of Windows 10 Home Edition Update Features (PDF. 2.6 MB) and have given me permission to republish the Windows 10 Update Model flowchart from their paper here under the Creative Commons Attribution 2.0 UK: England & Wales License. Their flowchart which is shown here describes how software updates are applied to Windows 10 v.1803 (the April 2018 Update) Home Edition:


 Note that this flowchart is based on research the authors performed using virtual machine experiments together with a review of the related literature, but they indicate in their paper that the flowchart is "not assumed to be exhaustively complete" since "the behaviour of the update mechanism is dependent on a complex range of user and system properties." Despite this disclaimer the flowchart accords well with my own understanding of how the Windows Update process works in Windows 10, and I hope that other readers will find it helpful too. 

I also recommend that interested readers read the paper from which this flowchart has been excerpted as it includes some fascinating analysis of survey results from Windows 10 users concerning their perception vs. reality of how the update process works.

How do our newsletter readers feel about the effectiveness of Microsoft's current process for keeping Windows 10 updated? Are there any changes you think Microsoft should make to how Windows updating works? Email us your comments: [email protected]

MVPS HOSTS file recently updated

Readers who can't or don't want to install adblocking software can use the HOSTS file on Windows computers to block all kinds of stuff. One way of doing this is by downloading a custom HOSTS file created by a former Microsoft Most Valuable Professional (MVP) who periodically releases updated versions of this HOSTS file.

Last week we shared some reader feedback on how to identify and deal with spoofed emails. A reader named Craig from Australia had some additional thoughts to share on this subject:

We use Cisco Ironport mail filtering appliances. Pretty much set and forget devices (yes, we do monthly checks for updates) and the stop at least 99% of spam from hitting our mail server.

Question: What kind of music would you prefer your local coffee shop to play over their speakers?They have a fair few smarts in them, one of which is sender reputation. If an IP address is a known spammer the device simply won't accept a connection from it. My understanding is the thousands of these devices installed around the world work together to determine what is spam and what isn't.

I've had users asking me to check the spam filtering is still working because they got ONE spam message. That tells me it's doing a pretty good job.

Phishing emails are pretty rare on our systems. We still watch out for them tho…

Ask Our Readers - Laptop with best keyboard (new question)

Christiaan from South Africa sent us the following question which we're redirecting to our readers for their suggestions:

Hello! We need to buy some new laptops for our sales team just now. Question for your readers: what brands/models have the best keyboard? Dankie!

Great question. I often miss my old ThinkPad from way, way back in 1994 that used to run Windows 3.1 -- not that I miss Windows 3.1 of course, but I miss the wonderful clickitty tactile-feedback keyboard that laptop had. Most laptops I've used or tried out these days have crummy keyboards that I fund…find dffici…uccu…ltt to typeonwitho utma kingmi steaks.

Factoid - What's in your ears, bud?

Last week's factoid and question  was this:

Fact: Electric cars may be good for the environment but they're likely to be bad for America's system of highways and roads. That's because federal, state and local governments rely on fuel taxes for the money needed to fix potholes and repair crumbling roads:

Question: How do you think U.S. federal, state and local governments will respond to this problem? And what about other jurisdictions like the UK, Europe, Australia, Canada etc? Is road maintenance funded differently in your country?

Frank from Germany responded to this question:

Hi Mitch, I don't know how it is in the US, but here in Germany, it's not mandatory that taxes are reinvested in the area they were generated from. For example, the fuel tax is about 40 billion Euros a year (41 billions in 2018), but only 5 billions a year are used to invest in road infrastructure (both combined, new streets and maintenance of existing ones). The rest goes into other ministeries that can't cover their expenses with their own income.

So I don't see this as a big problem for keeping road infrastructure intact -- at least not in the coming years. Should we be completely electrified one day, then a part of the "current-tax" will be used for this for sure…

Another reader named Bruce commented as follows:

I've long thought that, instead of gas tax, governments should using a mileage tax to determine how much one should pay.

I'm ok with the government knowing how far I've driven, as long as they don't know where I've driven.

Interesting idea, not sure how they could implement without knowing where you drive though.

Also a couple of weeks back we posed this question: "What kind of music would you prefer your local coffee shop to play over their speakers?" A reader named Matthew responded with:

Liquid Mind! It is the most soothing, peaceful music you can listen to. Bar none. Makes for great background sound when trying to drowned out conversations in a coffee shop while studying for a certification exam:



Liquid Mind is the work of Chuck Wild, keyboardist from the 80s band Missing Persons.

OK checked it out but IMO the synth pads are pitched about two octaves too high for me to consider it "background" music for doing any real work. My own go-to music when I wantread a book or write up a report is Seasons by Gabriel Lee:



I actually own an original copy of the CD of this title and have played it oh, about a zillion times over the years. 

Now let's move on to this week's factoid:

Fact: US music fans throw more money at vinyl, CDs than iTunes downloads now.

Source: http://www.wservernews.com/go/kbks8aq0/

Question: Do any of our readers still listen to music on CDs? And do any of our readers actually collect old vinyl records and/or purchase new ones? Or does everyone just listen to music on their phone using earbuds? SPEAK LOUDER, I CAN'T HEAR YOU, MAYBE I'M GOING DEAF FROM USING EARBUDS ALL THE TIME
