The Problem: so you’ve logged out of your windows XP computer to find that when you try to log back into your account you cant type your password.
According to Microsoft support this problem may occur if you have installed any of the updates that are described in the following Microsoft Knowledge Base articles:
884883 Multiple versions of Comctl32.dll may cause both Windows XP style and Windows Classic style windows to appear in Windows XP
908531 MS06-015: Vulnerability in Windows Explorer could lead to remote code execution
893086 MS05-016: Vulnerability in Windows Shell that could allow remote code execution
921398 MS06-045: Vulnerability in Windows Explorer could allow remote code execution
900725 MS05-049: Vulnerabilities in the Windows shell could allow for remote code execution
923191 MS06-057: Vulnerability in Windows Explorer could allow remote code execution
The Solution: not necessarily a fix but I did find this work-around that seems to work, use the classic logon screen to log on. follow these steps:
Press CTRL+ALT+DEL two times while the Welcome screen is displayed. For example, press all three keys at the same time, release all three keys, and then press the three keys again.
The Problem: a pop up at startup notifies the user that “Sonic Focus drivers must be loaded for this application to work” and your audio may or may not be working. also noteworthy is that this issue seems to be caused by using windows update to update the audio driver, specifically; “IDT High Definition Audio Codec”. avoid/hide this one if you can.
A Sonic Focus dialog box telling you something you don't want to hear.
1. Go to your system drive, typically your “C” drive
2. Go to Program Files
3. Go to SigmaTel folder
4. You should see an Install Shield Wizard, install it.
Alternative Fix: not necessarily a fix but it will at least get rid of the annoying pop-up.
press Start -> Run, and type “msconfig” in the command box. this will open the System Configuration Utility window.
Click on the “Startup” tab
Find IntelAudioStudio in the Item list.
Clear the checkbox.
Additional Information: check out the intel forums on this exact issue.. it will cover much of what I’ve said here with some additional ideas.. but I can only vouch for what I’ve written here as being something that worked for me, enjoy.
The Problem: When accessing the Windows Update Web site to check for and install updates, you receive error number: 0x80072F76
The Specifics: according to Microsoft support, this error is caused by interruptions in communications between the computer to be updated and the update to be downloaded. the specific error: ERROR_WINHTTP_HEADER_NOT_FOUND. this clued me into the fact that there was at least some communication taking place.
The Solution: In my case, I found the issue to be with my hardware firewall. but I imagine this issue can be caused by any number of network related issues, anything preventing or hindering network data. so a good course of action for this error (or related errors) is to turn off any unnecessary network/security software and take a look at your hardware.
