I guess many people know the issue of having a screen saver forced active after a some time through a group policy in a corporate environment. This is usually done to make sure systems are locked during breaks if people forget to press Win+L (or Ctrl+Alt+Del and then Enter). While that may well help IT security, it turns problematic when giving presentations for extended periods of time. Having to move the mouse through the presentation pointer every few minutes or dash back to the PC once the screen saver has kicked in, again, is simply annoying. On your company's systems you may be able to get the system admins to allow configuration of the interval or allow for disabling the screen saver, but on foreign systems you're often lost. But...

Disabling a group policy'd screensaver on Windows
...a nice gentleman by the name of "Average Midget" has come up with a helpful piece of software called Screen Slayer (ScrSlayer). He published it in a thread on the Leoville Town Square forum. Quite a difficult place to find it 
.
It basically moves your mouse by zero pixels every time 80% of the configured screen saver timeout has passed. Thus Windows sees the mouse moved and starts counting again. This works in Windows XP and Vista for me.
As experience tells me, the software and its documentation through the forum thread will vanish sometime off the Internet. Thus I replicated the latest version of the full version of ScrSlayer.exe (including a GUI), the lean version of ScrSlayer.exe (without a GUI) and the three pages of the forum thread on 13.08.08 here: ScrSlayer.zip [213 kB].
Thanks Average Midget, nice work!
Update:
21.04.11 It looks like the Leovilletownsquare link is redirecting to some new forum installation now. No ScrSlayer info found there 
. Google still finds a copy of the old fusionbb software here. Let's see how long that one stays around.
The ScrSlayer.exe also works in Win7. Amazing.
As I've seen a copy of the ScrSlayer.zip on a Saudi Arabian blog (not that he linked the source...), I'd like to give checksums so people can verify the integrity of their downloads:

Hello,
great piece of software, it was very useful to me
best regards
Thank you very much for the information, and a very big THANK YOU to the not-so-average midget - I owe you a beer!
Thanks a million. This has been really paining me a lot.
Regards, Subhash
This tool is really well done, a big thank you to the original author and also to you for preserving it.
Awesome, Talk about thinking outside the box ..
very nice tool.. much appreciated.. with this tool I had remove the screen lock for our company computer.. its very annoying to have it locked every after 2 mins. while waiting for a call
huge call center rep
If screens lock in your call center after 2 mins somebody seriously needs to talk to the IT manager. I find it amusing that he thinks a 2 min timeout is a viable security measure while agents are obviously able to run non-systems-managed software on the PCs. The latter is a serious security issue.
Thanks a lot !!!
Thank you very much. Great work!
I have also found Kaliro Screen Control
which can do the same thing. You can also get it to turn off the screen and return to the lock screen at your own interval in case you forget to turn it off. It can also store screen images in a folder every time you hit print screen - very handy. Find it at http://sites.google.com/site/kalirosupport/
Very cool! I was doing a vanity/paranoia search and found your post. I'm glad people found it useful. The one thing I wanted to add, but never got around to, was a way to specify a "cutoff" time. There were a few times where I accidentally left it running at work. Oops! I appreciate that you gave credit. That was nice, thanks!
someone seriously needs to bash IT manager's heads on a regular basis because the level of paranoia and over-use of security features is epidemic.
This is not a rant, it's real life security issue: example of choice: winlogon password rules and expiry. if IT decides that passwords have to use caps, numbers, punctuation, and change every week they inevitable force users to stick post it notes on the laptop with passwords on it.
Seriously, someone hit over-zealous IT managers on the head for me please. thanks!
