To one of PCs. Ready for update at midnight.

$Windows.~BT is the file on my C Drive. 4.04GB on my Windows 7 Pro system.

Apparently the file size is different to every PC.

3. I'll prolly try Win10 Enterprise on a box

Only Windows 10 Enterprise users will be able to update in a way that resembles the current Windows 8 scheme. By opting for the Long Term Servicing (LTS) branch, Enterprise users will be able to defer feature updates for years, electing to receive only security fixes during that time.

4. I just installed a fresh version of win7 on an empty partition

To see what the final version of Win10 will look like. Win updates are ridiculously slow. I'm probably going to have to wait a few days just to get this installation up to date before I can ever imagine actually getting win10.

I'm glad to hear that they tried to get some upgrade files on computers before the crush but I have to say waiting 20+ minutes to see possible updates (let alone downloading them) is pretty bad on MS part. I know I will not like win10 but posts like yours make me want to at least try it.

Thanks again.
