Hi, I would suggest you to do a SFC scan. System File Checker (SFC) checks that all Windows XP system files are where they should be as they were by default and not corrupted, changed, or damaged.a. Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.b. Click Continue or supply Administrator credentials if prompted.c. In the Command Prompt window type the following, and press Enter:sfc /scannowd. You should see the following on-screen message:§ Beginning the system scan. This process will take some time.§ Beginning verification phase of system scan.e. Verification % complete.f. Once the scan has completed, test to see whether the issue that you are experiencing is resolved or not. For further reference, check the KB article mentioned below. Description of Windows XP and Windows Server 2003 System File Checker (Sfc.exe) http://support.microsoft.com/kb/310747 Also, I would suggest you to refer the article mentioned below.Description of the Windows File Protection featurehttp://support.microsoft.com/kb/222193 Thank you and Regards.

I dont have one..can i restore it online? No and I suspect the advice received in your other response will not help because it relies on presumptions that do not exist in your situation. What is your computer make and model? Do you have data on the computer you need to safeguard? You need not only to repair the damage to your computer operating system but also to eliminate the possibility that the damage has been caused by malware. It is always sensible in this situation to run a check for malware Download and install Malwarebytes (freeware version for home users only), update definitions and run in safe mode. Disable other security software whilst you are doing scans. http://www.malwarebytes.org/ Download and run SuperAntiSpyware (Free Edition) http://www.superantispyware.com/download.html Hope this helps, Gerry Cornell

Maybe someday the XP forums "Ask a question" dialog will ask these questions automatically when a new thread is started so I do not have to ask them every single time. It might even be possible to resolve an issue in a single reply when enough information is provided.Please provide additional information about your system:What is your XP Version and Service Pack?Describe your current antivirus and anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc.If you do not have a genuine bootable XP installation CD that matches your currently installed Service Pack, you will not get far with instructions to run sfc /scannow.Windows File Protection wants to replace a file from the backup copy it keeps in the dllcache folder and WFP has found that the backup copy of the file on your system doesn't look right, so it complains (there is a list of 3498 files that WFP knows about).When you see the complaining message, if you click Cancel and choose to "keep" the afflicted file, you will see a warning message and then a message like this in the Event Viewer System log:Event Type: InformationEvent Source: Windows File ProtectionEvent Category: NoneEvent ID: 64005Description:The protected system file taskmgr.exe was not restored to its original, valid version because the Windows File Protection restoration process was cancelled by user interaction, user name is Jose. The file version of the bad file is unknown.As you can see, the file that WFP is concerned about is clearly stated in the log, so now you know what the file is.For the above example, I used my Task Manger file (taskmgr.exe) to recreate the problem. You will have to see what your Event Viewer message says.When you know what the file is, you can decide what to do about it. There are probably already other copies of the file(s) on your system or you can get the file(s) from another source.A shortcut to Event Viewer is to click Start, Run and in the box enter:eventvwr.mscClick OK to launch the Event Viewer.Check your Event Viewer System log and look for an event sourced by Windows File Protection.If you double click an event, it will open a Properties window with more information. On the right are black up and down arrow buttons to scroll through the open events. The third button that looks like two pages on top of each other is used to copy the event details to your Windows clipboard.When you find an interesting event that occurred around the time of your issue, click the third button under the up and down arrows to copy the details and then you can paste the details (right click, Paste or CTRL-V) the detail text back here for analysis. Remove any personal information from your informationafter pasting if you are compelled to do so. Do, or do not. There is no try.I decided to save up points for a new puppy instead of a pony!

When you see the complaining message, if you click Cancel and choose to "keep" the afflicted file, you will see a warning message and then a message like this in the Event Viewer System log:Event Type: InformationEvent Source: Windows File ProtectionEvent Category: NoneEvent ID: 64005Description:The protected system file taskmgr.exe was not restored to its original, valid version because the Windows File Protection restoration process was cancelled by user interaction, user name is Jose. The file version of the bad file is unknown.Worth a point towards your puppy!Hope this helps, Gerry Cornell
