- You intend to keep it for about five more years.
Yes you can keep it as long as you want! Windows will not effect that and costumer support will be at least 5 years. Windows 8 support will end January 9, 2018 and extended on January 10, 2023
It does not have a touch screen
It doesnt metter, touch screen will not effect your PC oweral all performance* it is designed to work on touchscreen devices as well as on normal screen.
I use TrueCrypt. I need full disk encryption, but not necessarily with TrueCrypt.
The development of TrueCrypt was ended in 5/2014 after Microsoft
terminated support of Windows XP. Windows 8/7/Vista and later offer
integrated support for encrypted disks and virtual disk images. Such
integrated support is also available on other platforms (click here
for more information). You should migrate any data encrypted by
TrueCrypt to encrypted disks or virtual disk images supported on your
platform.
So you should consider stop using TrueCrypt. I cant think of any reason why you cant use some other encription. And ofcourse that windows 10 will have some encryption support.
- It's a Lenovo Thinkpad X230..
On Lenovo website, there is an offer if you buy now Thinkpad X230 that you will get Windows 10 for free. (I know that everyone gets Windows 10 for free, but I think that company is advertising windows 10 for that device )
So, what was your question again? Shall I upgrade to Windows 10 from Windows 7?
