Windows 10 build 10135 has leaked onto the internet, just a day after build 10134 leaked. There are no noticeable differences between the two builds so those who installed 10134 probably don't want to waste the bandwidth downloading this one.
Of course, considering this is an unofficial leak we advise you do not install this leak. Furthermore, the initial leak is a modified ISO, so that's even more of an incentive to not install. If you must download, I'd wait for an original ISO to leak.
If you'd like to know what's new, check out our 10134 video as that covers all the new changes found in todays leak.
