* Modify OS.isWindows to check if OS is Windows first before checking version.
Previously OS.isWindows checked if the windows version matched the one required. This worked fine, except for the fact that it would end up comparing a linux kernel version to a windows version as it didn't check if the platform was Windows in the first place before.
This caused issues as it would throw an error when comparing with non-semver linux kernels (such as Fedora). Now it checks if the current platform is Windows first, and if not, immediately returns false.
Resolves: #2396
* Fix formatting for OS.ts
