Common Computer Questions Clients Ask
Our computer technicians answer some common – and not so common – questions from clients about computing, issues and errors, the technology, and maintaining a healthy computer system.
You may be asking how do I block my neighbour’s wifi networks, or you’re absolutely frustrated in the amount of networks shown in your wifi list.
Hiding your wifi networks is quite possible in Windows 10. It just not as simple as finding the offending wireless network and flicking a switch, but it’s actually not that hard to do.
We’ll show you how below.
Discover your wireless networks
Start by opening up a Command Prompt with administrator rights. Click the Start button, type “cmd”, right-click on the Command Prompt (desktop app) entry and select “Run as administrator”. Then, type the following command in the black command prompt window:
This will give you a list of wireless networks your Windows 10 system is aware of.
Write down the wifi network names of the wireless networks you want to hide from your computer system. You can also open up the notepad text editor and copy/paste them to a temporary text file – you can do this by simply clicking the Start button, type “notepad”, click on Notepad app to bring this up.
Do not record your owned wireless network names since you most certainly do not want to hide those!
You will see each wireless network name after the each “SSID #” entry. ps. ignore the other “Network type”, “Authentication”, and “Encryption” entries. Once you have completed recording your list, you can type this into the black command prompt for each wireless network you want to hide:
You will want to replace the [[wifi-name-you-recorded]] part above with the name of whatever wireless network you want to hide. Remember to keep the quotes.
How to display what wireless networks you have hidden
If you ever want to review what wireless networks you have hidden, simply open up a command prompt and type this:
How to make visible a hidden wireless network again
To unhide a previously hidden wireless network and make it visible again to Windows 10, open up a command prompt, and type the following command:
[[hidden-wifi-name]] needs to be replaced with the name of the wifi network you hide previously. You can get a list of hidden wifi networks from the section above.
In order to check if an email is dangerous or fraudulent, we go through a number of quick processes to give us some idea if the email we’re looking at is legitimate or not.
Hover over every link in the email and look at the real link that is shown, taking care the primary domain matches what is expected.
Never open any attached files, no matter how dire the email makes it sound. After all a scammer want you to generally do two things – open their fraudulent link or open their attachment.
If you really really must open that attachment (read this as “just do not”!) we would save the attachment to a known location on the computer, then upload it to Virus Total. Virus Total is a free service that scans files and urls across 55+ anti-virus products. This gives some degree of confidence that the attachment is good or not. However, we still would never handle an attachment – it’s just too dangerous in today’s world.
Scams also operate much quicker these days and have access to the same tools as you do – so that clean result from Virus Total does not mean its in fact clean. It’s just means that the scammer has constructed their attachment in a way that anti-virus have not picked up on it yet.
Sometimes you just want to take a screenshot of your windows display.
There is three easy methods to record your screen:
1) Using the Snipping Tool in Windows 10
Click the Start, type ‘snip’ and click on Snipping Tool (Desktop App) to open up the Snipping Tool application.
Click New from its toolbar, drag a box around what you want to screenshot and it’ll appear in the Snipping Tool. Click the diskette icon in the toolbar (or File | Save As if you have no idea what a ‘diskette’ is) and save the image.
This is the recommended method of getting a small screenshot of part of your desktop.
2) Using keyboard PrintScreen button
At the top-right of your keyboard is usually a set of three keys, with the left most one being the print screen button. Pressing this button copies the entirety of the current display into the Windows clipboard.
The next step is to copy the clipboard into a file. Click the Start button, type paint and click the Paint Desktop App entry. Paste the contents by pressing ctrl-v or clicking Paste on the toolbar. You can now edit and save it to a file by going to File | Save.
The downside to this method is it copies the entire display, with no cropping at all. Also if you have multiple monitors it will also copy all screens resulting in one overly large image.
3) Take a photo (with your smartphone)
Definitely not the best method but it does the job and especially convenient if you just want to bring some information with you away from the computer. Simple, easy and quick.
There are different types of ransomware. However, all of them will prevent you from using your PC normally, and they will all ask you to do something before you can use your PC.
They can target any PC users, whether it’s a home computer, endpoints in an enterprise network, or servers used by a government agency or healthcare provider.
- Prevent you from accessing Windows.
- Encrypt files so you can’t use them.
- Stop certain apps from running (like your web browser)
Ransomware will demand that you pay money (a “ransom”) to get access to your PC or files. We have also seen them make you complete surveys.
There is no guarantee that paying the fine or doing what the ransomware tells you will give access to your PC or files again.
