Apparently there is a way to emulate chmod on Windows:

Apparently the way the above works is that Windows has file permissions and they are more complex. To access them, turn off (uncheck) Windows Explorer -> Tool menu -> File Options -> View -> Use simple sharing. Then right-click any file or folder, to access the Security tab. This is known as Windows ACL (access control layer?). You may turn on (check) Use simple sharing again after making any settings to Security and these settings will be retained. You may need to be logged on as a user in the Administrators group to access some permissions on some files, i.e. User Accounts in Control Panel and see Start menu -> Run -> lusrmgr.msc and gpedit.msc.
