Metered connections on Windows 10 post Creators update install:

For Windows 10 Users on tablets and laptops that connect via phone hotspot or other "low download quota" services you need to be aware that there has been a change in the way that Microsoft handle windows updates over "metered connections"

This page tells us that: 

"A metered connection is an Internet connection that has a data limit associated with it. Cellular data connections are set as metered by default. Wi-Fi and Ethernet network connections can be set to metered but aren't by default. Some apps might work differently on a metered connection to help reduce your data usage. Also, some updates for Windows won't be installed automatically." 

As you can see by the description and by the screen shot below, some updates will still be downloaded even over a metered connection. This is a change from previous versions of Windows and may cause you consume more data than expected especially if you use multiple PCs connected to your "low download quota" service. 

You need to be aware of this and ensure that you have enough download quota to cope with the demand.

ESET /NOD32 have released a small utility which you can use to check if you have the appropriate Microsoft updates that protect you from the NSA EternalBlue Windows vulnerability which includes WannaCryptor and any future copycat malware that uses this vulnerability. 

You can download at the link below and just double click to run. 

It only takes literally a second to do the check.

Takeaway message: ALL PC's on a business network should have a UPS, as well as the servers and network hardware (such as network switches).

ALL PC's on a business network should have a UPS (uninterruptible** power supply) as well as the servers and network hardware (such as network switches). 

A workstation or PC UPS will help to protect against hardware failure, database & file corruption and lost time due to unexpected workstation power off events. Additionally (although not really measurable) a UPS can also significantly extend the life of the PC by reducing the voltage fluctuations that come in from the energy company, and the negative effect that low voltages or "sags and brownouts" have on the PC electronics.

This is the least expensive item I can find from a reputable supplier: 

[Edit: Recommendation removed, the cheap units are just as expensive as the option below]. However my experience with those cheap ones is that they last for the duration of the warranty but not much more, I have had to spend hundreds and hundreds of dollars in the past on support costs for "cheap" UPS units that were purchased to save money. 

A better quality unit entry level unit would be something like this: 

Socomec NeTYS PE Tower Line Interactive UPS, 650VA $115.00 at last check (plus about $30 freight) Link

** The word uninterruptible, is a little misleading. Yes, a correctly functioning UPS will prevent interruptions in the event of a short power outage, if the correct size of UPS is purchased you can expect about 20 minutes of battery backup. Before that time the PC needs to be shut down automatic or manually. The higher the overall "load" the less time you have, or, to put it another way the bigger the UPS (measured in "VA") the longer you will have on battery backup.

Your Windows PC, laptop or tablet can have a lot of external devices plugged in that will play sound here are some examples on just one of my PC's: 

• 3.5mm stereo socket's (headphones, speakers, even 5.1 surround sound systems)
• USB speakers 
• USB headphones 
• Bluetooth headphones
• Other Bluetooth speakers (There is a trick here as well) 
• HDMI (often combined with video) 
• Optical (Fibre optic cable) 
• Coaxial (RCA)

Good (normal business grade) NBN… in my office:

I'm posting this because I have heard a number of comments about NBN being not much faster than ADSL2, of course it depends what NBN are you talking about; $20 a month, no brand, speed limited NBN or something more substantial?

The above graph shows that the measured download speed is over 2 times as fast as the fastest ADSL2 (and perhaps 3 times as fast as the typical ADSL2)

Upload speed is around 20 times as fast as ADSL2

My 39 days of no internet or phones during changeover is just a distant memory now (mostly)

FIVE key considerations to help with protecting your data, your network, your identity and your money. 

1. Don't be an administrator on your own PC for normal day to day work. Create a separate admin account and just be a normal "user" unless required. 
2. Don't run outdated software; Old versions of Windows, Java, adobe other apps 
3. Have a good quality antivirus installed, working with a current subscription 
4. Don't visit undesirable or illegal sites (or if you must; learn enough to mitigate the risk, run in a sandbox, another user account, a Virtual PC, or another PC setup for this task) 
5. Social engineering - Be vigilant when opening links or emails, unsolicited mail or other peoples USB drives 
6. (Bonus) Get a good antispam/antivirus system that blocks you from as many threats as possible before they enter your network or PC. 
7. (Bonus) Use complex passwords that are unique for your internet services

I'm reposting this article from October 2013 even more relevant today than then... 

The recent Adobe hacker-fest has again brought up the subject of passwords so here is my recommendation... 

There are a full set of password rules and suggestions that are already widely recognised as being crucial for online security, see here for a great article: http://www.thegeekstuff.com/2008/06/the-ultimate-guide-for-creating-strong-passwords that pretty much says it all. 

However, particularly relevant for now, you need to ensure that your passwords are always different from each other, if your Adobe password has been compromised you don't want that same password to have been used for your banking. 

Take some time to think about the quality and diversity of your online passwords would all your online accounts fall domino fashion if one was breached? 

If you're having difficulty in tracking all those passwords consider a password manager, there are a number of different product options. I use https://lastpass.com/ which is available in a free version or paid if you want the smartphone apps as well ($12 per year).

Finding how to logoff or switch users on Windows 10 is less "discoverable" than it could be, I have made a quick guide on how to do this here.

If you are a junior IT admin or an administrative staff member that needs to access the servers on occasion *and* you have Microsoft Hyper-V visualization this article may help: (It may just confuse you more as well, sorry about that if that's the case).

Beware the current run of Australia post malware emails, see below (this one is not really from Australia post). Remember to hover over the link in Outlook with your mouse before you click, in the screen shot below the link goes to a Russian web site: I expect is some sort of ransomware.
