I have R Reproducibility problem peculiar to my my windows 10

Question

I run some R simulation I wrote before now but gets different results from same version of R. I tried such simulation on a web interface and I got the previous result. What must have changed on my windows 10?

set.seed(1)
rnorm(20)

#[1] -0.62645381  0.18364332 -0.83562861  1.59528080  0.32950777 -0.82046838
 #[7]  0.48742905  0.73832471  0.57578135 -0.30538839  1.51178117  0.38984324
#[13] -0.62124058 -2.21469989  1.12493092 -0.04493361 -0.01619026  0.94383621
#[19]  0.82122120  0.59390132

as against my new result

#[1]  0.46081080  1.34310205  0.99716829 -0.36762421 -0.13198270  1.77709933 -0.46426860 -0.17384681 -0.40401399
#[10]  1.41481488  0.03121604 -1.28415064  0.58393330 -2.06891059  0.12002295 -3.25983598 -0.41697647 -0.51721040
#[19]  0.89266537  1.33231147

I triad same on a mobile app called

R compiler

I got exactly the result

#[1] -0.62645381  0.18364332 -0.83562861  1.59528080  0.32950777 -0.82046838
 #[7]  0.48742905  0.73832471  0.57578135 -0.30538839  1.51178117  0.38984324
#[13] -0.62124058 -2.21469989  1.12493092 -0.04493361 -0.01619026  0.94383621
#[19]  0.82122120  0.59390132

I now know that my windows 10 has effect on my R result.

My question is what must have changed on my Windows that is affecting my R result?
