one reason for the GWUtil97.dll error is:
- A DLL file that was needed for more than one program on your computer was accidentally deleted when you uninstalled an unused software program, and now the program that needs that file can’t find it.
- A new software application has been installed on your computer and it wrote over top of the DLL file that another program needs. Sometimes the version that has replaced the old DLL file isn’t compatible with the older program.
- Sometimes software installs and uninstalls don’t work the way they should and a DLL file gets damaged or corrupted.
- Malicious spyware or adware software has been secretly loaded on your computer and is messing about with your Windows DLL file structure. *Recommended: use this free download anti-spyware scan to see if you’re infected.
- Occasionally, your computer has a hardware part that’s dying, like a hard drive or RAM chip and your DLL files are being mixed up or corrupted as a result.
- Damage to your Windows Registry is affecting the way your DLL files operate.
then 2 problem with user log in-
to fix do this go to 'C:\Documents and Settings\USERNAME' , where USERNAME is your user. Then right click on the folder and go to 'Sharing and Security...' Click on the security tab and make sure that SYSTEM has full permissions. If SYSTEM is not there, add it and then give permissions
delete ntuser.dat in your profile, windows will recreate it or if you dont want to take the risk then...
Search for ntuser.man & rename it to ntuser.dat if you don't pick up ntuser.man, then logg in with safe mode & networking as administrator, rename the corrupt profile, then, logg in again as yourself so that a new profile is created.
