What you should know about xpsp3res.dll Service Pack

xpsp3res.dll is not a Windows system file and is known to frequently cause computer problems. The file xpsp3res.dll is found in the C:\Windows\System32 directory. Frequently occurring are file sizes such as 351,744 bytes (38% of all these files), 352,768 bytes, 23,040 bytes, 21,504 bytes or, as the case may be, 22,528 bytes.
This so-called dynamic link library (DLL) contains all the functions that have been transferred to a separate file. These transferred functions are available not only to this particular program, but can also be used by other applications. For this service - unlike Windows' own system services - there is no good description available. This process does not have a visible window, and does not appear on the taskbar. Xpsp3res.dll does not come from Microsoft and is not part of the operating system. The file also can also affect other applications by changing their properties. Such manipulation can cause an application to do things other than what it is intended to do. The original file was created by Microsoft. The file itself can therefore be considered trustworthy. xpsp3res.dll appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files. For this reason, 44% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.

If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant. It's a fact that many trojans try to cloak their true identity by calling themselves xpsp3res.dll. With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.

How to tell if xpsp3res.dll (Service Pack) was uninstalled cleanly

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of Service Pack. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for Service Pack or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.

What to do if a program does not uninstall

The easiest way to remove any kind of software cleanly and accurately is to use an uninstaller tool. Because the uninstaller automatically creates a backup, there is no risk of anything going wrong.
