Ctrl + Alt + Del on a Mac with Windows

I'm using Boot Camp to run Windows on my Mac.

Last night I tried to compress the memory of C, then after that finished, it told me to

Press Ctrl + Alt + Del to restart

How do I press these keys?

One of these should work. Option is Alt in Windows. Your Backspace key generates Delete (You might need to press the Fn key to generate Delete)

Control + Option + Delete

Or

Control + Option + Fn + Delete

You should also try:

Ctrl Shift Esc

Here is an alternative. This worked for me in a slightly different and more complicated setup (connecting from a Mac to a Linux server through SSH and then from the Linux server to a Windows Server 2016 server through Remote desktop protocol using the rdesktop Linux RDP command line client).

In Windows:

1. Click Start menu
2. Click in the search bar
3. Type "powershell"
4. In the search results, click "powershell.exe"

5. In the PowerShell shell that opens, type the following:

   Powershell -noprofile -nologo -noninteractive -command "(new-object -ComObject shell.application).WindowsSecurity()"

If PowerShell is not available, instead search for "cmd.exe" and in the cmd prompt, type:

explorer shell:::{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0}

Note: if your Mac keyboard layout is not English US, it might be hard to get the {, } characters in cmd.exe. In that case try the following:

• Change you keyboard layout on your Mac to English US (use System Preferences)
• In X11's preferences, check "Use system keyboard layout"
• In Windows, make sure to also set the keyboard layout to English US.

To press CTRLALTDelete on a macOS machine, ^⌥delete will not work.
You will need to press ^⌥fndelete to get it to work.
the delete key on macOS is backspace, and fndelete is the real delete.

Many of the answers here are confused.
The reason there is so much confusion is that many people who have only ever owned Macbooks & others with short keyboards may be unaware that an extended keyboard has both true Delete and Backspace keys, whereas a short keyboard only has a Backspace key.
Windows wants the 'true' Delete key.

Pressing Fn Backspace will send 'true' Delete.

So on an extended keyboard Ctrl ⌃ Alt ⌥ Delete ⌦ is the correct method.
On a short keyboard you need to press Ctrl ⌃ Alt ⌥ Fn Backspace ⌫
The Fn Backspace method will also work on an extended keyboard if you really feel the need.

Note:
Opt == Alt in all cases.
Some Mac keyboards actually say Alt, some say Opt & some only have the symbol ⌥.
It's all the same key.

You should be able to use one of the following:

• Ctrl+Option+Del
  

• Command+Option+Del
  

• Ctrl+Option+Fn+Del
  

• Command+Option+Fn+Del

Bootcamp Windows Partition. I tried 'every combination' that I found and none of them worked when I tried to log in to Windows. I solved this CtrlAltDelete problem by plugging a PC keyboard in to the Macbook. Worked like a champ! Be sure to change that "user must press CtrlAltDelete" setting in User Accounts once you are in!
