Hi Ejike, Thanks for the post! For the Rundll.exe corrupted issue. I suggest you click Start, input cmd in the search box, then input the command sfc /scannow, this system file check will automatically help you fix the corrupted system files. If it does not work, follow these steps manually fix this. 1. Insert your Windows 7 CD/DVD in your CD/DVD ROM. 2. Click Start, input Run, then press ENTER. 3. Type expand X:\i386\rundll32.ex_c:\windows\system32\rundll32.exe in the Open box, where X is the letter of your CD ROM Drive. 4. Restart the computer. (If you don't have the Windows 7 CD/DVD, copy this rundll32.exe in another working computer.) Additionally, for those PDF files, I think you don't set the default software for that format file. Please refer to this: Change which programs Windows uses by default.
