Windows 10 Tech Preview gets its first big update
Welcome to a laptop battery specialist of the HP Battery
When Microsoft released the Windows 10 Technical Preview at the start of October, it promised that we’d get lots of rapid updates as it fixes bugs and rolls out new features — and it wasn’t lying! Yesterday, just three weeks after the initial Technical Preview release, Microsoft rolled out the first major update. There are three major new features in Windows 10 build 9841 — a notification tray, Battery Sense, and Data Sense.
In my eyes, though, the most important aspect was that it was really easy to install the new build; you just click a button. With Windows 10, has Microsoft finally tackled the abomination that is the Windows upgrade process with battery such as Hp dg103a battery, Hp PB994A battery, Hp PB991A battery, Hp HSTNN-DB36 battery, Hp Pavilion G60 battery, Hp Pavilion dv4 battery, Hp Pavilion dv5 battery, Hp Pavilion dv6 battery, Compaq Presario CQ70 battery, Hp Pavilion ZT1200 battery, Hp XH260 battery, Hp Pavilion N3200 battery?
Upgrading to the new build was very easy: You head along to PC Settings, hit “Update and recovery,” click the “Preview builds” tab, and then “Download now.” The new preview build took a while to download — it’s about 2GB or so — but eventually an “Install now” button appeared.
After clicking the Install button, you go through a process that looks a lot like a normal Windows 8 installation. You get a number of black screens with the Windows flag on it, with messages like “Setting up a few more things” at the bottom. Eventually, after a few reboots, you get the rainbow-colored “OMG, Windows 10 is almost ready to go!” sequence — and about 60 seconds later, you’re at the login screen.
The whole process — upgrading from build 9841 to 9860 — took 13 minutes. As far as I can tell, nothing was broken by the upgrade — though I think a few settings, like my microphone volume, were reverted to the defaults. Sadly I didn’t time how long it took my laptop to upgrade from OS X 10.9 to 10.10, but I think Windows 10 was faster by a few minutes. Overall, I am very impressed by Windows 10’s new one-click in-place upgrade.

You cannot perform this upgrade process from the Desktop Control Panel applet called Windows Update. I don’t know if you will be able to in the future, or if Microsoft is going to continue on with this rather odd and clunky interface dichotomy.
