Solved file system error (-1073741502)

[bbxrider]

win 7 pro, 64 bit, after uninstalling an hp printer package, suddenly I can't run any 'system' type programs, e.g., cmd.exe, regedit, sfe.exe. I get the error in the subject line? wtf? are we back to vista style problems again, please say no

ahh should have remembered, the ultimate fix, reboot
