i am having this weird problem with hidden folders in win 7 RTM 32 bit. When i select the show hidden files option in Folder options i cant see the hidden files.. However when i select the Dont show hidden files option i see the hidden files..the options seem to have been interchanged. the problem here is that i cant see the Hidden protected system files as they can be seen only when u have checked the 'show hidden files' option before unchecking the 'Hide protected operating system files' also i have no virus problems coz basically i am a cautious and safe pc user.to be sure i already scanned with kaspersky 2010,malwarebytes antimalware and even trojan remover..no problems found. i dont want to format n reinstall again.if possible can someone give the default registry values pertaining to the hidden folders so that i can compare and see whether they are changed... any help would be apppreciated...thanks
