run CMD as admin and enter: slmgr.vbs -ipk "key from 1st Post" (Without quotes an old key maybe works,too) And then slmgr.vbs -rearm and restart. Ignore the appearing messages!
There's a "skip this for now" in the key screen. Maybe you could also try the GLVK key. Because you said this key doesn't work.
LOL, it said "installation key", I've put it back, unless people will tell me it can't be used for installation.
Is there a way to upgrade to Enterprise yet? Also how would I go about integrating a language pack into the iso for a clean install?
DO NOT POST OR LINK TO FAKE GENERATED KEYS. Reason 1: Microsoft are likely to send DMCA takedown requests. Reason 2: You then end up with fake keys being mixed with real keys and people can't tell the difference. If the mod team keeps seeing them and if people keep trying to bypass our filters then we will start banning people for it.
Upgraded my 2015 XPS 13 from 10135 to 10147 and it was quite painless. Before upgrading I unpinned Project Spartan and old Store from the taskbar. The process went fairly quickly. After upgrading, the machine was already activated and all device parts are working correctly (including the microphone). Not gonna mention things I read above, but will go through several changes: Battery life approaches that of Windows 8.1, but still not that good. Battery saver is still non-functional. Microsoft Edge has seen a lot of improvements on ECMAScript and features (including the much-requested continuous background audio/video, e.g. after switching from or minimizing YouTube), but is still not bug-free (e.g. pinning The Verge on the start screen/menu does nothing but crash the browser). Mail & Calendar also deserve a honorable mention for being upgraded visually and functionally. You can now open two instances of some Universal Apps through right-clicking their taskbar icons (however, there are minor inconsistencies, such as Calculator's second window being very big). Tablet Mode is quite improved, especially with new animations, but there are still bugs (e.g. after leaving tablet mode, I still have a full-screen Start, not a menu). Dark theme is closer to being finished system-wide (tested via registry). The new Store has been updated but there are no visual differences from the previous one (Back button still taking up a whole row). Tiles now have both the sliding and the rotating cube animations (without visual glitches - tested also on an ATI) depending on the level of content that is being switched to (e.g. picture-headline is sliding, switching to different news items is cube animation). Cortana displays a prompt sometimes when idling, especially on a cold boot. Overall the WinRT environment is a bit more stable. This is a very polished build, IMO (despite some under-the-hood bugs that I didn't mention, including CPU time/thread management for intensive applications).
