Have you ever wanted or needed information about the hardware in your computer? Did you know that Windows 7 contains a command that can provide you with a list of your hardware components including memory information? It does and it is very easy to explore and to save to a file. There are other helpful little bits of information hidden in the recesses of Win7, so let’s take some time to explore a few of them.
First let’s check out the system information command. Go to Start and type “cmd” in the Search box (without the quotes), then press Enter. This will open a command window in which you can type “systeminfo”, also without the quote marks. Press Enter again and you will get a detailed profile of your computer. This list will include the processor, BIOS version, operating system and updates, both installed and available memory and much more. In all, there are thirty-two categories of information provided by this command. You can scroll up and down through this information. Then, if you want to save this info to a disc file, type the command “systeminfo /FO CSV > systeminfo.csv”. Again, without the quotes. This file will be saved in the directory shown at the beginning of the command line. So be sure you remember this location when you go to look for the file. A CSV file can be opened in a spreadsheet or a database program. Now you will have a ready reference for the components which make up your computer. It’s not a bad idea to create this file and keep it for reference purposes.
Of course, if you are a frequent reader of Dr Herb’s “Computer Buffet” you would have seen references to “Belarc Advisor”. This free program gives you a profile of all the hardware and software on your machine. It also highlights problem areas such as non-working applications. The software information can be quite extensive. The last time I ran this application on a Windows machine I had more than eight pages of information. Far more than I really wanted. The systeminfo command gives you a summary which is printable in one page.
There is another use for system information. If you type this “system information” command into the Start-Search box, it will bring up a list of applications before you finish typing. Select “System Information” from the list and click on it. You now have a double pane window with a tree of topics on the left and an information window on the right. The first item is a general summary of system information similar to the information we obtained in the command window. But there are other more detailed topics under the headings in the tree list. For example, hardware resources, components and software environment. Under components you will find a very important topic – problem devices. Hopefully, at this point there will be nothing listed when you highlight this topic. But if there are, it can lead you to solutions for some of your hardware problems. Under software environment you will find a topic called Startups. This lists the applications that are loaded into memory when your computer starts. Always something worth knowing.
Another interesting item under Software Environment is Windows Error Reporting. This gives you a detailed list of applications that have “misfired” or produced system hang-ups. This can be useful when you have problems with either Windows or third-party applications. All of the errors I found on my system were related to missing drivers that I had to install after installing Win7. Once that was completed the errors disappeared. Yes, I said that with crossed fingers – no use asking for bad luck, right?
If you haven’t backed up your computer recently, then you should try the backup built into Win7. In previous versions of Windows the backup application provided by Microsoft was very slow and some versions were very limited in the media to which they would write the backup file. It was also useless when you changed your Windows version as the file formats in the backup file were not compatible with the newer version. In the Win7 help files there is information on how to restore a backup made with Vista to Win7. So at least the latest versions should be compatible.
These latest versions of the backup applications are much faster than previous versions. To try the backup applications, open the Control Panel and select System Security, then backup and restore. Here you have several options. You can do a complete image of your hard drive, just backup your data, or make a system repair disc. If you did not get a Windows installation disc when you purchased your computer, then the first thing you should do is make a system repair disc. All you need for this is a blank CD and then just follow the on-screen instructions. The next step would be to make a complete image file, preferably on an external drive. It’s really not a good idea to put it on the same drive you are imaging even if it is a separate partition. Why? Because when the drive fails you won’t be able to access the image file to restore anything to a new hard drive. Even if you do have a Windows installation disc the repair disc plus the image file are a better solution for restoring Windows and your files after a drive failure. The image file you create will be more current than the original installation disc when it comes to Windows updates. It will also include the installation of all the applications you added after you purchased the system or upgraded to Win7.
Once you have the repair disc and the image backup you can start doing data backups, or you can create new image files periodically. There is no need to make image files unless you have added applications or made substantial changes to your system. Windows file backup can be set to run automatically to save your data files. It will also add new folders and files to the backup list when you create them. I would also recommend that this be saved to an external drive.
Do you have a need for a system to remember user names and passwords? Win7 has a credential manager which can be used for storing user names and passwords in an encrypted file. This application can be found in the Control Panel under User Accounts. If you can’t find it, try searching within the Control Panel.
I frequently have a need to write down short notes or references to information I found on the Internet or in other sources. This is where Sticky Notes comes in quite handy. You can run this application by typing “stikynot” in the Start – Search box and clicking on the program that shows in the popdown menu. Alternatively, you can go to All Programs – Accessories and click on Sticky Notes. These can be placed anywhere on your desktop. You can also pin the application to the taskbar so it will be readily available. Just right click on the menu item or one of the sticky notes and select “pin to taskbar”.
If you want to see the minute by minute performance of your computer, try typing “resource monitor” in the Start - Search box. The complete term will show up before you have completed typing and you can then click on the item. This brings up a window in which you can view the memory utilization, cpu utilization and other resources as you use your computer. It’s a great way to see which applications are using the most memory.
By playing around with the Control Panel and other aspects of Windows 7, you can find many helpful built-in functions. You can also query the Help files. On my system the Help response is much quicker than it was in Vista and XP. I also found that many subjects are better explained and more detailed. So if you are stuck on something, try the Help application that’s on the Start menu. The more you play with Win7, the more you will find that may be useful.
