Why doesnt windows 8.1 update show up in my windows store?? I have installed all updates in WU. And i run w8 pro, legal activation with an MAK key.
Irrelevant to the OPs question. In terms of activation, the RTM image already available in MSDN is just as usable. A GA updated image is not going to change any activation situation, so no point waiting for it.
if you are using KMS key, then windows 8.1 wont show up in the store. Even same thing happened to me. I had to reinstall entire windows 8.1 from sratch.
