I suggest it  because, if like me, your company has and antivirus
software which block some actions on programs without good reputation
you're lock with officials distributions. Lukly Emacs is on the list
...

see https://whitelist.kaspersky.com/advisor

For example, at my work, writing to
c:/windows/system32/drivers/etc/hosts is forbiden for not known
applications like the ones you're compiling yourself (and trust me this
bother me quite a lot).

If could help you in testing, ask for it.
