Updated to win10; try to use that cool scr and found same issue;
Try to trick ms restriction and found only one very long solution:
- enable logging of screensaver invoked events;
here instruction via gpedit:
windows - Run a batch/cmd upon screensaver - Super User
- now you will able to start other comand or app when screensaver starting;
- goto C:\Windows\System32
- copy Bubbles.scr and rename to Bubbles.exe
- then config task to run C:\Windows\System32\Bubbles.exe with argument /s (administration->taskcheduler)
- use some windows screensaver and config to use 1 min or more; (or use 'runsarver' with empty options from upper link or create your own empty.exe and
rename to .scr and install with right menu, etc)
Found cool app to customize hidden screensaver features:
Downloads / Software / Windows Screensavers Tweaker
(work with small bugs but work as needed under win10)
All work fine one cons checkbox to lock PC must be unchecked;
Maybe later will try to play more with task configs, etc; or will create own app to run Bubbles and on exit lock PC or bat file;
hope people will have fun with my solution
