change MSE update interval

You also have to grant yourself full admin rights; taking ownership is not enough.

Yeah, you need to grant full access to administrators to change that key.
I use an old registry explorer for that (Registrar Lite: it's a pity it became a shareware ).

lol regedit is king

Only it didn't work in Regedit.  :'(

It's even easier if you make a REG file with wanted change and schedule it in Task Scheduler to be executed under SYSTEM credentials.
I've tried changing on Vista x64 and i'd have to destroy all the permissions in order to change it. By using Scheduler, SYSTEM itself creates the modification and all the permissions stay as they were before. And i've successfully changed the check interval. It's so much easier and you don't mess up all the permissions. It's much easier changing this under Windows XP, where you just enable full rights, modify it and then disable full rights again.

Registrar Lite 6.0.1 does the job. http://majorgeeks.com/Registrar_Lite_d469.html
It's the latest freeware version of Registrar Registry Manager that became a shareware :'(
A very useful registry tool with acquire permission option.
