We could instead do the global search by the following script (regrep.bat) in command line:
@echo off
for %%a in (HKLM HKCU HKCR HKU HKCC) do (
echo [Regrep] Looking for reg value under path %%a
reg query %%a /f %1 /s
)
which could find the search term under all path recursively.
e.g.
Find a single term:
regrep system32
Find a word with space
regrep "internet explorer"
