About Prevent PC Sleep
Windows decides when your screen goes dark and when the machine sleeps, and it does not ask whether you are in the middle of something.
Prevent PC Sleep holds both open. What makes it different is that it shows you the two numbers it is holding: the screen timeout and the sleep timeout, read from the power plan you are actually on, counting down on the real idle clock. Switch it on and both dials stop where they are.
The two holds are separate
Keep the whole machine up, or let the screen blank while the PC keeps working. A long download overnight does not need your monitor burning with it.
On a laptop
Windows keeps a shorter set of timeouts for when you unplug. This reads the pair that is in force, and tells you when holding the machine awake is going to cost you battery.
How long
Run it until you stop it, until a time you pick, or for a set number of minutes, after which it lets go on its own and your normal power plan returns. Nothing is edited and nothing is left changed behind you.
No account. No sign-in. Nothing leaves your PC unless you choose to send feedback. No ads, and nothing held back behind an unlock.
Built for Windows 11, and at home on Windows 10.
