You probably have a fancier phone than me, then

On the newer versions of Windows:

 

ALT+CTRL+C turns the screen monotone. I say this not because its particularly useful, but for the same reason we tell people about right alt + arrow keys

I think that more phone camera lenses are coming with infrared filters these days so I suspect that one's days may be numbered

In Command Prompt, or PowerShell get the make/model, serial number, and other properties of a computer:

 

 

The commands:

 

1. wmic csproduct get name
   
2. wmic bios get serialnumber
   
3. wmic csproduct get uuid
   
4. wmic csproduct get vendor

Check whether a remote control is working (or just check it for flat batteries) by viewing it through the camera app on your phone. If it's working, you'll see the IR LED lighting up when you press buttons.

 

Dont think it works on IPhones! Especially on any ive had

To run Google Chrome without plug ins or extensions create a new shortcut for Chrome. In the target box enter:

 

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" /high-dpi-support=1 /force-device-scale-factor=1 --disable-extensions --disable-plugins

[6Foot2]

Disable Incognito Mode In Chrome [Chrome 68, Windows 10 1803]

 

Create a new DWORD (32-bit) key in Windows Registry at:

 

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies

 

Name this new key IncognitoModeAvailability and set its value as 1.

The following PowerShell one-liner could be incredibly useful for troubleshooting...

 

Show all events from every event log (300+!) in given time range & then filter/search

 

Get-WinEvent -ListLog * | Where-Object { $_.RecordCount } | ForEach-Object { Get-WinEvent -ea SilentlyContinue -FilterHashtable @{LogName = $_.LogName; StartTime = '[color="#FF0000"]07:25:00[/color]'; EndTime = '[color="#FF0000"]07:30:00[/color]'}} | Select-Object * | Sort-Object TimeCreated | Out-GridView

remove permanent maker from classroom whiteboards by going over the marks with dry wipe marker and wiping clean with a cloth. Any remnant is easily cleaned with a little board cleaning solution and cloth.

 

Note: This may contaminate your dry wipe marker so try to match the colour you are removing or use an old, nearly expired, marker.

[vascodagama]

Remotely rename a computer using Powershell with

 

Rename-computer –computername “Old-ComputerName” –newname “New-ComputerName” –domaincredential administrator –force –restart

 

This also changes the name in AD keeping all associations

 

Edit: Just remember to replace the angled speech marks (“,”) with standard speech marks ("), as this can sometimes cause scripts to error. Thanks DJ-1701!

Hand sanitiser gel also works nicely to clean up whiteboards. As do first aid kit swabs (isopropyl?).

want to quickly access classic control panel on Windows 10?

 

windows + r, then type control.

True, but if all you have on you at the time is hand sanitiser...

 

I always bugged the science techs for methanol or acetone. Works absolute wonders at dissolving ink (and with acetone, a fair few plastics too, so be careful). Make sure to open the windows when you're using it though - once got rather overcome with acetone vapour and nearly passed out!

[jthompson]

I know you can buy spray bottles of isopropyl (of varying strengths). That might be less dangerous.

 

I am not a chemist.

[mikeprice]

IPA (isopropanyl alcohol) is also great for cleaning up old laptops

 

I used it on some old rubbish ones that the SEN people wanted for WWW access only

The kids would have gone mad if they were given them in the state they were in - but after a good scrub with IPA they looked almost new - good enough to fool the kids anyway!

The following command will reboot you directly into your BIOS/UEFI firmware from Windows 10.

 

shutdown /r /fw /t 0

 

If you reboot into the UEFI firmware often you could create a shortcut using the command above or even add it to the Win+X menu. This might be a bit quicker/easier than the Shift key method (hold down Shift while clicking on the Restart option on the Start Menu).

Tried that on several laptops and it doesnt work for me just get "couldn't find the environment option that was entered (203)"

[Arthur]

Tried that on several laptops and it doesn't work for me

Which version of Windows 10 are you using?

 

Edit. Some Googling reveals that the /fw switch was added in Windows 10 v1709.
