Removed battery to find model and it was there turned it back on and and got a blue screen with a spinning wheel and a statement Cleaning up 0% Don't turn off computer.  Help please

Every week, Windows Update automatically runs, and depending on the week, can then lock up the PC for HOURS while it searches for updates, downloads them, and installs them -- often rebooting more than once in the process.

The "cleaning up" message indicates that it failed during doing this and is trying to repair itself -- which basically, it can not do.

Nothing will run while this is happening because Windows Update locks up the PC, so your running Turbo Tax was just a coincidence.

This problem is very difficult, if not impossible to fix -- from the standpoint of making repairs and leaving your stuff intact. Some steps for trying this are listed below, but they are very hard to do and if they do not work, you are faced with doing a complete Windows reinstallation to get your PC back working again.

First thing you need to do is see if you can restart in Safe mode -- by doing these steps: https://www.tenforums.com/tutorials/2304-boot-into-safe-mode-windows-10-a.html

If you don't know how to start using Advanced Startup Options, then read this: https://www.tenforums.com/tutorials/2294-boot-advanced-startup-options-windows-10-a.html

Then, follow these steps to reset Windows Update: https://www.tenforums.com/tutorials/24742-reset-windows-update-windows-10-a.html

If these work, when you finally reboot, you should then be able to login to a working Windows desktop.

If these don't work, then report that back here as we will then have to provide you information on reinstalling Windows.
