Solved win 8.1 updated automatically and now mouse freezes

I have a Toshiba laptop - Satellite C55-B5299. Bought new 3 months ago. It came with Windows 8.1. It periodically automatically installs updates from Microsoft. Last night and this morning it did that. During this, it rebooted several times. I did not power it down during any of this.

Anyway- when I now login, the mouse arrow freezes after a few seconds. There is no physical mouse. The laptop has a touchscreen where I move the mouse symbol on the screen. I am not running any apps. I am just logging in.

To overcome the freeze, the only things I can do are a physical pressing of the power button, or using ctl-alt-delete.

The laptop has only a few 3rd party packages. Chrome, Dropbox, OpenOffice 4.1.1.

I have done several reboots. Sometimes the mouse never appears. More often, it appears as described above. When the mouse is frozen, intermittently, a busy circle appears by the mouse arrow.

Any ideas ??? I am stuck. [I am writing this on another computer.]

I solved it. Maybe this will help you. I found that doing multiple shutdowns of the computer, I got an error message that the computer did not shutdown properly, during a subsequent reboot. The Toshiba computer offered the option of going into a diagnostic mode, with advanced options. One of these was to reinstall the OS - which would delete all my personal stuff. Luckily, I could do this, because my stuff was all backup elsewhere. After the reinstall, the mouse was OK.

I am guessing that the problem I met was due to one or more of -

1. chrome,
2. OpenOffice
3. some background downloads from using chrome for 2 months
4. the default OS stuff

Anyhow - for now, I won't install chrome. [Grr.] I can live with IE. I will soon have to install OpenOffice.
