HOWTO: Lock Remote Computer on Windows 10 via the Internet
To some people, the apparent lack of the computer locking function during Remote Desktop Connection is a major flaw. This would be the case, if it were true. Though the standard Windows key + L does not work during a Remote Desktop Connection, you have the ability to save a shortcut to your desktop that will allow you to lock the computer.

1. Right-click on your desktop, select "New," then "Shortcut."
2. Type rundll32 user32.dll,LockWorkStation into the "Type the location of the item" text field, then click "Next."
3. Type a name for your shortcut into the "Name" text field (e.g., "Lock My PC") and then click "Finish."
4. Double-click on your new shortcut to lock your computer. This will work even from a Remote Desktop Connection.
Execute Remote Computer Lock via Interner
Not everyone knows, but on computers, laptops and tablets with Windows 10 there is a device search function via the Internet and a remote computer lock, similar to that found on smartphones. Thus, if you have lost a laptop, there is a chance to find it, moreover, remote locking of a computer with Windows 10 can be useful if for some reason you forgot to leave your account, and it would be better to do it.
First of all, about the requirements that must be met in order to take advantage of the possibility described:
The computer being locked must be connected to the Internet.
It should enable the "Find My Device" feature. Usually this is the default, but some programs for disabling the spyware features of Windows 10 may disable this feature as well. You can enable it in Options - Update and Security - Find My Device.
Microsoft account with administrator rights on this device. It is through this account that the lock feature will be executed.
If all specified is satisfied, you can proceed. On any other device connected to the Internet, follow these steps:
1. Go to https://account.microsoft.com/devices and enter your Microsoft account login and password.
2. A list of Windows 10 devices using your account opens. Click "Show Details" on the device you want to block.
3. In the properties of the device, go to the item "Find my device." If it is possible to determine its location, it will be displayed on the map. Click the "Lock" button.
