POSReady 2009 is based on the Windows XP kernel and get updates until 2019. I want to know, if i can apply that on normal XP, but i get a error of version mismatch.

So i looking in the update.inf/update_SP3QFE.inf and it checks only some registry entries:



The solution is simple. Create a text file with this content::



Save as .reg file and doubleclick to import it.

POSReady2009 Updates will now install on a normal XP and Windows Updates shows also the updates for POSReady2009

ATTENTION: Use it you own risk! These updates are not tested on a regular XP system and could damage your system


Instead PosReady you can also use WEPOS or WES. A reboot is not required.

XP x64 is based Windows Server 2003, but new Server2003 updates will not install on XP x64.

But i found a workaround by applying a modify update.inf. Since update.exe will check the integry of update.inf, you need to swap the files directly:

1. First you need to download manually the update from microsoft.com and then execute with the switch /x to unpack it (ex. C:\xpupdate).
2. Create update.cmd:



3. Copy update_SP2QFE.inf to new_update_SP2QFE.inf (in folder c:\xpupdate\update)
4. On new_update_SP2QFE.inf you need to delete this.



and the end (end of line):



5. Execute update.cmd

You can view install.log to show, if the installation is successfull. A reboot is required.

Hello,

for XP x64 you need Updates from Windows Server 2003 x64, because XP x64 (NT 5.2) is based on the same Server 2003 architecture. But for Windows XP x64 you can only get the updates until 2015, because Windows Server 2003 was discountined at that year.
