hi
my sys (win 7) environment variables got deleted.And it doesnt allow any downloads.
When i try to click on Advanced System Settings from My Computer properties,
it gives an error like:
"Windows cannot find %windir%\System32\systempropertiesadvanced.exe"
Please guide.
 
Back up a bit. HOW did they get deleted. When did it start? Did the download issue start at the same time? Did you run a virus and malware scan?

You can set the variables in the registry if you can't open the proper window though the GUI. http://best-windows.vlaurie.com/environment-variables.html , look towards the bottom of the page for those entries you need to edit.

You may need to do a Repair setup of Windows if things got really messed up.
