Although Windows 10 is only a couple of short weeks away, HP has joined a few other PC manufacturers that won't be shipping Windows 10s for launch day. As Windows 10 builds are still rolling out very quickly, I wouldn't be surprised if Microsoft misses their lauch day - at least with a finished product. Either way, the OS feels pretty close to me and it would feel all finished if companies would make Windows 10 drivers available. Yes, I know Windows 8 drivers work, but it feels that something is missing when you can't find the proper download.
On Monday, HP said in a press release that it doesn't anticipate having products available with Windows 10 preinstalled until "mid-August into October." That means it will be a minimum of two weeks after Windows 10 ships to Windows Insider members and as possibly as long as a couple of months before HP product running the OS becomes widely available.
