I installed, removed, installed and removed again service pack 2. I like the addition of Tablet 2005, but it will not allow me to run internet explorer, the control panel, search button, or use windows explorer. I have had no luck finding anything that will work, and I tried repairing the explorer.exe file. The machine I am using is the Compaq TC1000. Any suggestions would greatly be appreciated. Also, I already applied the enhancements from HP's site, with no luck.
