Does this stop automatic restarts after windows updates?

Super happy with this portable app. Use it to prevent Windows 7 machine from logging me out. Tried a bunch of workarounds to prevent the machine from logging me out (work laptop) when I'm using it at home, no joy. THIS program worked like a charm. THANK YOU!

WOW no comments for such a long time, this is a program I have used for many years and it still works great for me even now while using Windoze 10 does just what it says and does it perfectly.

I think "Don't Sleep" should win an award for the most updated program on TPFW. :-) Works well though, thanks.

I've been using Don't Sleep for some time now and it works great for me. It updates frequently but I never had a problem with the many previous versions. I use it when doing routine unattended maintenance, when making large backups and downloads.

I can't see the analogy to Shut Down Timer? That looks like a programme to set when to shut down the PC.

The thing about "Don't Sleep" is that it blocks shutdown or standby mode. A lot of new PC will automatically shut down when idle, which is annoying if you are for instance downloading stuff on a mobile internet connection, meaning that connection is broken and download lost.

I been using "Don't Sleep" for a while now, and must say it is a fantastic little programme :-)
