My registry editor has been disabled. What is the solution?

don't know if you don't mind using reg cmd and if its avail in home editons

for small change and viewing
reg add
re query
combined with reg export can be safer and quicker then regedit when used
properly

for details use reg /? or reg <anyregcmd> /?

of course reg is of no use if you don't have the required right to the
registry.
