Many people asking for help with Windows 7 are not providing enough information for their question to be answered reasonably.
An easy way to provide this information is to:
Launch System Information:
Go to -> Start -> Search -> Type msinfo32 and press enter
Provide important information depending on the problem you are having:
Windows 7 Build
This will be listed under Version. For example, the RTM will appear as 6.1.7600 Build 7600, while the leaked SP1 build will appear as 7601 v.153
32 or 64 Bit
This is listed under System Type. You will either have an x86-based PC or x64-based PC.
Other information that you may want to list depending on the type of problem you're having:
Downloaded Beta From
Other OS on the Computer
This will help provide people with an accurate description of your problem. In System Information, you can also go to File -> Export and save this information to a text file. You could then attach this file to your post which would give detailed information on your system.
Please also use the Search feature as someone may already have posted on a problem similar to yours recently.
How can I show others my computer's specs?
You can now fill out additional details in the User Control Panel which will show your stats to the world on every post you make. To do this, simply go to "Edit Your Details" in the User CP and fill out any fields you want to show on your profile.
You can use different online services and software to find out your computer details, or you can contact the manufacturer you bought your computer from, like Dell or HP.
Please look into which forum your problem category falls into. For example, graphic or display problems should be posted in Windows 7 Graphics, and so on. This will help reduce clutter and help people find your post more quickly.
