Error in command line "The system cannot find the path specified."

Not sure what I did but since past 5 weeks but I am getting this error The system cannot find the path specified. when I run any command or start cmd. Here is what I get when I start command line:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.
The system cannot find the path specified.

C:\Users\Jason>

How do I troubleshoot this error?

Try the following.

1. Open the Registry Editor (press +R, type regedit and hit Enter) .
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun and clear the values.
3. Also check HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun.

Your Path must be wrong. The issue is that your command prompt can't find any programs to match what you're entering.

• From your desktop, rick-click "My Computer" and click "Properties"
• In the System Properties window, click on the Advanced tab.
• In the Advanced section, click the Environment Variables button.
• In the Environment Variables window , highlight the Path variable in the Systems Variable section and click the Edit button.

I don't know the default PATH values you need, but I am willing to bet you have something that isn't right. Post what you have here.
