I currently own a Compaq TC1000 and have enjoyed it for the most part. There is one problem I am having that I need help with resolving. When upgrading to Windows XP Tablet Edition 2005 (or Windows XP Service Pack 2), I encounter a sever problem when the installation is complete. I receive no errors at all during the upgrade and even after rebooting. Once I log back into my Tablet pc, I can no longer use Internet Explorer or the explore.exe command at all. I can do without Internet Explorer, but cant do without the ability to explore my hard drive, or search for files. When I try to perform any of the above mentioned tasks, the error I receive is as follows: Explorer.Exe - Application Error: The instruction at "0x77f83905" referenced memory at "0x0e562e97." The memory could not be "written." Once I uninstall XP service pack 2, the error disappears and the Tablet performs flawlessly. I would love to be able to use the enhancements in Tablet Edition 2005, but I need the ability to search and explore the hard drive. Any help with this would greatly be appreciated, thanks.
