As stated already by 97WideGlide, executables wont necessarily get you going. You will have missed a lot of files. IE: Microsoft Office, or Word if you will...just coping word.exe does not guarantee you that it is going to run on the new computer. That being said you should as stated by 97, is to copy your Data....Etc... I wont go into any more detail on that as it has already been said by 97.
What I will say is that if your System is a Windows TABLET PC.....make sure you have RECOVERY disks or Reinstall Disks to wipe the drive and reinstall.
Otherwise if you do not, You may lose use of the Tablet portion of the laptop. The Tablet PC may have a recovery partition on the hard drive, which you may be able to use to reimage the drive that way. You will want to consult your manual and such to make sure that this is true etc.
Also if you have no recovery partition and no Media to recover or reimage the drive, you will need to find replacement Tablet PC installation disks. Of which are Very rare and hard to come by.
Ebay is about the best source these days. And usually cost you as much for the disks as it would cost you to pay for the license and disks.
