Windows 7 Uptime

[MrMaguire]

My daily use Windows 7 Professional system has been running for 80 consecutive days without reboot, sleep, or even logging off. I'm posting this simply because I think a few members here will get a kick out of it, and also because I'm feeling that itch to switch back to XP for a while. (I usually like to switch between the various computers and operating systems I have.)

I booted the system in late March and it's been running flawlessly since then. Not one problem at all. I have (so far) missed 3 months worth of updates, and in my view the system is no worse off because of that.

This is Windows 7 Professional 32bit with SP1 running on an Intel 320 series 120GB SSD, inside an 11 year old Dell Latitude D610 laptop with a Pentium M processor at 2.13GHz. Not bad for an old machine, eh?

I knew I remembered this topic or a topic like it existed. I was just checking my system uptime and... well

I see that the two sets of numbers do not seem to match up. I wonder if one could be wrong, or if there is a roll-over on the Days counter on the Performance tab...
System Idle Process hours 13636 (568 days) vs Uptime in Performance tab: 143 days.

The CPU time shows the sum of process times of all CPU cores. So, if you add up the CPU time of all processes shown in Task manager and divide that by 4 (in your case) you'll get your uptime.

Makes sense to me!

Decided to turn off my main Windows 7 PC at home. Task Manager Up Time on the Performance tab has it at 703 days.

Lost power two days ago, while on my attempt to break my previous uptime record. 4 hours before power was lost, this was logged in Event Viewer:

The system uptime is 60616898 seconds.

That's 701 days!

What about your UPS (Uninterruptible Power Supplies) . Batteries went dead ?

[Tripredacus]

The function of the computer is to go on websites, play a DOS game and has an IM client running so that I can send myself links or whatever when I am not home. There is no actual requirement that the computer needs to stay on for any particular reason and the only reason it does is because it can. So there is no point to use a UPS on it or any other computer that I run at home.

I have a more modest result, but I think it is quite worthy to show it.

Not sure if this is the case for Win7, but I do know that "uptime" in Win10 is easily cheated.

In Win10, you can do a full reboot to "reset" the uptime timer, go into Sleep/Standby/Hibernate two minutes later, wake the computer up a YEAR from now, and that uptime will show that YEAR.

No, in Win 7, if you transition the computer into waiting or sleep mode, then all the counters will stop, too, if you disable a computer from sleep in a year, then the work time will be at the time of shutdown.

Experienced a power outage last night.

The previous system shutdown at 4:23:00 AM on ‎2/‎23/‎2023 was unexpected.

Four hours previous, this log was generated: The system uptime is 38087169 seconds.

I am really thinking these experiments are going to be over soon, that computer needs to be replaced.

Awesome!

That's 1 year 75 days 19 hours 46 minutes 9 seconds.

I forgot to write the result here. Here is the last saved screenshot, exactly 2 years old. After that, the computer ran for another week and the HDD motor jammed, leaving a screenshot with 736 days of work on it.
