Windows 7 and SRT FIles

Hi,

Yeah, so I was downloading a theme for windows 7 off Microsoft website and others. Now i cant seem to get it back to its original [default] state. The administrative yes/no classic yellow sign now looks like a windows xp admin yes/no and makes an awful sound along with the error sound it makes.
^^^^^^^^ what i mean is that the alert sounds have been changed and i want it back to its default setting. How would one change it?

I can't seem to get any srt [sub] files to work on my computer anymore. I tried downloading k-lite codecs but my computer does not recognize it. Weeks before i downloaded them and installed it just fine.

my Conclusion is that something with the themes has severely caused some altercations within my cpu hard drive.

Was wondering if i could default the themes thing.

also when i sign into my computer that page has some how changed. how do i change it back?

Hello,

Right click on an empty spot on your desktop and click personalize. Then just select the theme you want. The default "Windows 7" Aero theme should be the first one in the list under Aero Themes. That should put everything back to what it was when you first installed windows 7. Assuming you or one of the themes you installed didn't hack or replace any system files.

ah thanks you 2. I guess my assumption on the themes messing with the klite codec has nothing to do with it not installing.

But i still dont know why it isn't I mean weeks before i installed it no problem?
