Windows XP System Restore Guide
- If you install a new application and that application's installation program is compliant with the System Restore API, which most are these days, then a new restore point will be created.
- Installation of Microsoft security and OS updates will trigger a Restore Point creation.
- If you choose to use system restore to restore to a previous restore point, system restore will create a new restore point prior to restoring a previous state in case something goes wrong.
- Before a Microsoft Backup Utility Recovery operation.
- Before installing an Unsigned driver.
- By manually creating a new restore point.
- By default at a 24 hour interval a new restore point will be made. This restore point will only be made if the system is in an idle state.
- If system restore is disabled and then reenabled a new restore point will be made.
- Registry (Contains Configuration information for application, user, and operating system settings)
- Windows File Protection files in the dllscache folder. (Used for protecting system files)
- COM+ Database
- Windows Management Instrumentation Database
- IIS Metabase (Contains configuration for Internet Information Server)
- Files with extensions listed in the Monitored File Extensions list in the System Restore section of the Platform SDK
- Local Profiles
- Windows XP passwords and hints are not restored. This is done so that you do not by accident restore an old password and then lock yourself out of the computer..
- Microsoft Internet Explorer and Content Advisor passwords and hints are not restored.
- Any file types not monitored by System Restore like personal data files e.g. .doc, .jpg, .txt etc.
- Items listed in both Filesnottobackup and KeysnottoRestore (More on that later)
- User-created data stored in the user profile
- Contents of redirected folders
NOTE: You need to be logged in as an Administrator to administer System Restore. If you are not logged in as an administrator you will not be able to follow these steps
WARNING: By disabling system restore you will delete all stored restore points.
If you see in the Status section, designated by the green box, that it is Turned off , then system restore is already disabled and you do not have to do anything further. If it is showing that it is monitoring as seen in Figure 1 above, then you should check the checkbox labeled "Turn off System Restore", designated by the red box. You should then click on the Apply button to disable system restore.
To enable system restore you should follow these steps.
By default system restore is enabled on Windows XP machines, so there is a good chance that it is already enabled if this is your first time working with system restore.
You should first go into the Control Panel and then double click on the System icon. If you are in the control panel and do not see the System icon, then click on the link that says "Switch to classic view" in the upper left hand side of the window. Now you should be able to see the System icon. After you double click on it you should then click on the System Restore tab. If system restore is turned off you will see an image like Figure 2 below.
If you see in the Status section, designated by the green box, that it is Monitoring a partition, then system restore is already enabled and you do not have to do anything further. If it is showing that it is turned off as seen in Figure 2 above, then you should uncheck the checkbox labeled "Turn off System Restore", designated by the red box, and then adjust how much disk space
To create a manual restore point select the radio dial labeled "Create a restore point", designated by the blue box, and press the Next button. You will then be presented with a screen similar to Figure 4 below.
At this point you should type the name you would like this restore point to be referred as in the field designated by the red box. The current date and time will automatically be appended to the name you choose. When you are done, press the Create button designated by the blue box. System restore will create the restore point and give you a confirmation screen with information like Figure 5 below.
At this point you can press the Close button to close the System Restore utility.
At this point you should select a restore point that you would like to restore. If a particular day has any restore points created on it the date will be in bold. You can then select the restore point by clicking once on its name, as designated by the red box in Figure 6 and then pressing the Next button.
If there are any problems with your computer since you restored to this restore point, you can revert back to your previous settings by going back into the System Restore Utility and selecting the "Undo my last restoration" radio button and pressing the Next button as show in Figure 8 below.

What is a Cookie?
A cookie is a text-only string that gets entered into the memory of your browser. This value of a variable that a website sets. If the lifetime of this value is set to be longer than the time you spend at that site, then this string is saved to file for future reference.
What are the purposes of cookies?
Cookies make the interaction between users and web sites faster and easier. Without cookies, it would be very difficult for a web site to allow a visitor to fill up a shopping cart or to remember the user's preferences or registration details for a future visit.

Step 2: Export the Address Book to a .csv file
Important Make sure that you follow this step if you use multiple identities in Outlook Express.
Microsoft Outlook Express 5.x and Microsoft Outlook Express 6.0 use a Windows Address Book (.wab) file to store Address Book data. The individual data for each identity is stored in a folder by user name within the .wab file that is used.
The only way to separate the Address Book data for different identities is to export the data to a .csv file while you are logged in as a specific identity. If the .wab file becomes dissociated from the user identities, the data can be exported only as one total. In this case, the data cannot be exported folder by folder.
There is another reason to export the .wab file to a .csv file. If the .wab file not exported to a .csv file, but the .wab file is shared with Microsoft Outlook, the addresses are stored in the personal folders (.pst) file in Outlook. When you export the file to a .csv file by using the File menu in Outlook Express, the correct contacts are exported. However, if the Address Book is shared with Outlook, you cannot use the File menu option to export from the Address Book. This option is unavailable.

Disable Windows Data Execution Prevention in Windows 7 & Vista
What is the “Data Execution Prevention”, short DEP?
The DEP Data Execution Prevention is a security feature that has been available since Windows XP SP2. You will also find this feature in Windows Vista and Windows 7.
It’s trying to prevent that certain applications and services can execute code from a non-executable memory region. It’s a useful feature that can help to prevent a buffer overflow and it even helps to fix problems for some games like “Age of Mythology, but it can also cause a lot of problems.
I am posting this solution how to disable and enable the Data Execution Prevention on request of a reader who had serious problems with this feature:
Question asked by Raaghav K.
I was using win7 for little bit time
it was not supporting softwares which were supported by XP
I guessed it to be the Data Execution Prevention in the 7.
While there might be other causes why your software is not running, I’ll try to explain you how you can turn off the DEP.
By the way, I sent a mail to all subscribers that all of your questions are more than welcome. I will try to answer them all, but give me some time so I can answer them properly. You can always post a question on our forums or send me a mail!
Does your CPU support Data Execution Prevention?
- Open the Explorer (Windows key + E) and right-click on “Computer”. Select “Properties” from the context menu.
- On the left click on “Advanced System settings”, click on the “Settings” button of the field “Performance”:
Go to the tab “Data Execution Prevention”:
On the bottom you can see if your CPU supports DEP.
If you want to find out if your CPU also supports “Hardware Virtualization”, then I recommend to download the tool:
“SecurAble” (which has been downloaded about 700,000 times!
As you can see above my CPU, an Athlon 64 X2 5000+ supports Hardware D.E.P. and Hardware Virtualization.
You can download SecurAble here.
Although this is about DEP, I want to quickly tell you what Hardware Virtualization is.
Quick Sidenote about Hardware Virtualization
Hardware Virtualization or better “Hardware Assisted Virtualization” is basically the built-in hardware support of CPU’s that is needed to run virtual machines more efficiently:
What the industry has seen lacking was support for virtualization at the hardware level to boost the performance of the VMM. This is because the x86 processor architecture did not previously meet virtualization standards, making virtualization on the x86 platforms difficult. Starting in 2005 both AMD and Intel made changes to their x86 architectures and added virtualization-friendly extensions.
On a second sidenote, Sony Laptops that run Windows 7 will have HardWare Virtualization disabled by default and therefore no Windows XP mode. However, you can re-enable it via BIOS settings.
How to disable Data Execution Prevention
Alright, as you can see above, you can’t simply disable the feature with a few clicks (that would be too easy, ha!)
Open the command line: “Start” -> enter “cmd.exe” into search field and hit enter.
Simply run the following command to disable it:
bcdedit.exe /set {current} nx AlwaysOff
You can enable it again with:
bcdedit.exe /set {current} nx AlwaysOn
Attention!
If you run this command and you are not able to start Windows, then run Windows in safemode and enable it again, using the command above. Start Windows in safemode by pressing F8 during bootup.
Turn Vista into Windows 7 for free
Every time Microsoft delivers a new OS it's possible to get many of the features of a Windows upgrade in the previous version of Windows. Windows 7 is no exception. Here's a roundup of a few things you can do to make Windows Vista as Windows 7-like as possible, without shelling out for the new OS.
We'll start out with a couple tweaks, then tell you about four free apps you can download. And a tip of the hat to the amazing Gina Trapani at Lifehacker, from whom I picked up several of these tricks.
First the taskbar. Windows 7 lets you "pin" apps to the taskbar and we can approximate that in Vista. Here's how.
Right-click on your taskbar.
Select toolbars.
And choose Quick Launch.
Now drag the icons you wish to "pin" into the left side of the taskbar.
Right click on the taskbar again and uncheck "lock taskbar."
Now click on the three rows of dots, hold down the mouse, and drag the bar over until you see all your icons.
Now, they look a little small like that, so let's make them bigger. Make sure the taskbar is unlocked.
Now right click on the taskbar again.
Select the view menu and choose large icons.
That's OK. But if you want a real Mac-like dock, forget all that and install RocketDock. It gives you a whole new Macish dock that you can put down at the bottom of the window instead of the taskbar.
But your Windows still looks all Vista-y. One more interface tweak before we move on. Download VistaGlazz 1.3. It's a utility that changes some system files to allow you to implement third-party themes on Vista. Launch VistaGlazz and, if you're sure, agree to allow it to modify your system files. I did it, and had no issues. But I make no guarantee.
Now you need a Windows 7 theme. Go to DeviantArt.com and get "Windows 7 Style for Vista." It should be by giannisgx89.
Download it, uncompress it, and then inside the Windows 7 Style folder, go into the theme folder and find the file called Windows 7 and the folder called Windows 7. Copy both to C:Windows\Resources\Themes\. (You'll need admin access to copy these.)
Now right-click anywhere on your Desktop and select "Personalize." Click on "Theme" and supposedly you can select the Windows 7 theme from the drop-down list. That didn't work for me, so I had to browse to C:Windows/Resources/Themes and choose the Windows 7 theme manually. Once you've got it, press Apply and you have a Windows 7 look!
You can also go to DeviantArt for wallpaper, log-in screens, and other Windows 7ish customization options.
Four free apps and we're done.
In Windows 7, Aero Shake kicks in when you shake an active Window, minimizing all the other windows. You can download a Vista version from LifeHacker for free.
Next you'll want the nifty Win 7 feature that halves the size of a window and docks it to the side of the screen. There's an app for that. It's German and it's called AeroSnap. You can get it at aerosnap.de.vu.
The Windows 7 calculator is also a lovely souped-up thing. Some intrepid hacker has actually pulled it out of Windows 7 and made it available on Box.net. You'll have to do a search to find it. And there's no guaranteeing it will still be there when you do. Is it legal? That's fuzzy. Probably not. But it is cool. Just make sure you back up your Vista calculator if you decide to replace it with this one. Just in case things go sideways on you.
Finally, Windows 7 has a much easier way to select Wi-Fi networks. It's not a perfect match, but NetSetMan from netsetman.com is much better than the default Vista manger and gives you lots of other powerful tools as well.
There are plenty of other tweaks, like turning off User Account Control and tricks to speed up startup, covered in Ms. Trapani's Lifehacker article as well as in a few of our Windows videos at cnettv.com.
