Last week, I finally managed to install Windows 10 Preview on my new Winbook tablet - one that has 2GB/32GB of space.
A few of the things I found strange. For instance, in Windows 7 and 8.1, I could set My Documents to any drive I wanted - it didn't have to be locked on C:\ Which is particularly handy in this setup, where I have a mere 32GB, and Windows 10 requires that you have at least 16GB of free storage space in C:\ to be able to install in the first place. I had done that in Windows 8.1, and now migrated to 10.
Now, OneDrive too has the option of being shadowed on your computer. That too, I had set to D:\ in 8.1. However, here, in 10, OneDrive doesn't allow its backups to be on D:\, and insists on installing on C:\ Which is irritating, given my limited C:\. And I can't upgrade it, since it's a NAND flash in TSOP package soldered to the motherboard, so I'm stuck w/ it. Winbooks don't come w/ 64GB drives, and the other tablets are a lot more expensive (this one was $100). Microsoft ought to retain that capability, and since this is a new version of the OS, w/ even things like multiple desktops (similar to virtual desktops in BSD and Linux), one thing I wish they'd do is introduce the concept of logical volume manager and let one extend the C:\ to the SD card, so that one can upgrade to 96GB or above simply by inserting a card.
I don't exactly get the point of Microsoft Edge/Project Spartan, and I didn't like it automatically importing my IE links w/o asking me. I typically have multiple browsers on my computers, and have different sites on each. (In this case, I've avoided downloading FireFox or Chrome due to the space issue). Also, Spartan loses the feature IE had since 8 and FireFox has always had - being able to stage an RSS on one's taskbar. Not good.
I however don't get the difference b/w desktop and tablet mode in this preview edition. It would have made sense if in tablet mode, they went into a Metro like screen (or gave us the option to), while in desktop mode, retaining everything that we had in 7. Incidentally, even in desktop mode, one can't make it look like in 7: one can only bring all those buttons down to where the Windows button is. Strange. Also, the control panel is now hard to find, although one can go to settings. Like today, I had to go through quite a roundabout way to install a new font.
Other than that, I more or less like Windows 10. I found the ability to switch keyboard languages rather neat, and their providing localizations to different versions of a language e.g. English really nifty. Other things that would be nice to have - being able to download Windows Phone apps from the store - apps like Yelp!, Fandango, et al. Also, under Video, to have the ability to create playlists (in iPad, one can create playlists of either audio or video music, which one can then hear in the car w/o taking the eye of the road).
Also, in Windows 8.1, in the Metro mode (in the Start screen), one could customize the looks and color of that screen (not the same as the desktop background or themes). Again, in Windows 10, this is lost. For now at least, anyway.
