With Rtools42, you don't need to run the Rtools bash, either, to check 
packages. You can use cmd.exe (or any other console/shell) or you can 
run the checks from R  (e.g. via tools::Rcmd). This has more details for 
R 4.2 with Rtools42 (but the same applies to R-devel):

https://cran.r-project.org/bin/windows/base/howto-R-4.2.html

With Rtools40 and R 4.0-4.1, this is almost the same but you need to 
adjust PATH in the running session of R (see 6.3.1 in R admin manual for 
the respective R release).
