Details

We noticed the same time the screensavers were disabled on win8 in bug 929473 that our bi-modal data in bug 908888 stopped being bi-modal.  There were no obvious changes that took place to fix this.

In order to see if these screensavers fixed this or not, we would like to revert the changes from bug 929473 for a couple days, then put them back.  We understand this is fairly trivial via group policy.

Please speak up if this sounds like a bad idea and what timing makes sense.
I like this approach. Great idea jmaher!
I'm guessing this hasn't happened yet?

Also, when it does happen, it should be during weekdays, since we noticed that the bimodal results happen much less during weekends. See bug 908888 comment 25.

looking forward to this, we will keep an eye on our results once we see this changed.
I have a GPO ready to roll this out. Is there a Win 8 machine I can use to test? I would like to test the GPO in a separate OU before rolling it out to the main Windows 8 tester OU.
Please try with t-w864-ix-016.

Thanks Mark!
Just for clarification, do we want the an actually screensaver, or do we want the screensaver timeout? And what is the amount of time we want to set?

Sorry for the delay. The GPO is ready to be applied to the tester OU. I just need a time frame to apply it. 

Once the GPO is applied, the machines should pick up the change within an hour to an hour and half, and then on the next reboot the change will take effect. 

Also, t-w864-ix-016 has been returned to the tester OU.

Does "tester OU" mean all the machines affected by bug 929473? (this is what we want).

If it's OK with you, I think applying it today (Wednesday) and restoring it before the weekend should work for us (or maybe even earlier if we'll identify what we need quickly). If we can't do it before this weekend, then mid next week would do (e.g. Tue-Thu, or Wed-Fri). Just post here when the machines have the screensaver again. Thanks.

So after all machines have picked it up, when will the next reboot happen (of all relevant machines)?
The GPO has been applied. 

After each test a machine is rebooted.
Hmm.. we have a slight issue. OMTC for windows was turned on yesterday, and backed out today (bug 899785 comments 6, 9). Since it affected talos results significantly (bug 946567), it might make it harder to interpret the screen saver effect.

Hopefully results from today and tomorrow would show the screen saver effect better, since OMTC is disabled again already.

So let's return the screen saver to off at the end of Friday (tomorrow) rather than at the beginning of the day, to gain few more hours of the screen saver effect. Thanks.
I will probably make that change when I have a couple hours left in my day on Friday. It makes me uneasy to make change and then takeoff even though it should just work. Would around 2 pm west coast be OK?
that should be just fine, thanks for all your help on this so far!
Just applied the disable screensaver gpo to the tester OU.
Thanks!
The experiment has been successful because we got good data to draw conclusions. Unfortunately, not the conclusions we were hoping for (turns out the screen saver was not the cause for the bimodal results).

Still, good data. Thanks :)
