Last night while doing some work for school on my pc, I realized that an update was being downloaded to my computer. I finished my work and was reading email, when prompted to install, which I did. After the install was complete, I was asked to restart the computer, which I did. Unfortunately, I could not get my computer back to the desktop with icons, start menu, etc.. The computer started as usual, the login screen, etc., my desktop picture was there, and NOTHING except for the following message: "EXPLORER.EXE - Entry Point Not Found".....and below that: "The procedure entry point SHCreateThreadRef could not be located in the dynamic link library SHLWAPI.dll." followed by a button with OK on it. Clicking on the OK button only closed the message box. No icons on my desktop, no system tray, no toolbar, no START button....NADA!
I have searched message boards, troubleshooting, the internet for help, but can find none. I cannot find anything with my specific message. There are plenty with "entry point not found" but not relating to SHCThreadRef or SHLWAPI.dll.
I tried rebooting, but the same thing happened. I tried SAFE MODE and LAST KNOWN GOOD CONFIGURATION.....nothing. Rebooting in NORMAL MODE doesn't produce any results either. I can, through CTRL-ALT-DELETE, get a couple of programs to open, but still can't get anything to work right. I cannot connect to the internet because my desktop icons aren't available. (I use an older version of CompuServe to connect to the internet, via dial-up, through special instructions, and a separate icon, to be able to use this version of CompuServe with Windows XP. I can't remember what that is, though.) I have seen suggestions to download HiJackThis and use it to diagnose, but I can't download it unless I can get to the internet. ( I am on my laptop tonight.)
I can't get to SYSTEM RESTORE, because I can't find it on my computer because I cannot access that part of the PROGRAMS menu. I thought about using the RECOVERY disk, but as of this writing, do not know where it is nor how to get another one, if possible. Recent A/C flooding caused much of my computer stuff to be placed here and there throughout the house.
Do I give up trying to remedy this by myself and taking it to a repair shop, and if so, can they fix it? Can anyone help? I am totally lost as to what to try next.
Thanx in advance for any help.
