The text cursor is that blinking line at the end of what you are typing in Windows.
The caret timeout is the time in milliseconds that the text cursor will continue to blink before it automatically stops blinking.
The default caret timeout is 5000 milliseconds, but you can change this time if wanted.
This tutorial will show you how to change the text cursor caret blink timeout for your account in Windows 7, Windows 8, Windows 10, and Windows 11.
EXAMPLE: text cursor blinking in Run (Win+R) dialog

Select (dot) Decimal, type in how many milliseconds you want for the text cursor blink timeout, and click/tap on OK. (see screenshot below)
The default text cursor blink timeout is 5000 milliseconds.
1000 milliseconds equals 1 second.
