Windows 10: Update Takes Forever

That failed install happened to me with the Dec update on the laptop. After 3 times I gave up and took it to a tech service. He used the(free) software clean/repair tool referenced here often to clear out presence of previous attempts and the install went in without fault. Now I cannot recall the name of that tool. But removing any traces of previous download solved the issue.

Tweaking.com is the source of the repair tool

 

Thank you I will give that a try, many many thanks.

This is the one Tweaking.com - Windows Repair Free/Pro

 

I was having a lot of trouble with this update as well. If you want to make this happen fast go to Microsoft and download the update and manually install it.

Go to Microsoft Update Catalog, key in the KB you want, KB3213986 in this case, and download it. About 1GB. Now to prepare your system, if you have had issues run the Windows trouble shooter. (Part of Windows 10). Best to run once just to be sure.

Type troubleshooting in the Cortana search bar, troubleshooting appears at top.
Click it, window opens, lower right side "Fix problems with Windows Update", click.
Window opens, click on “advance”, click on Run as administrator, click “Next”.
Should run clean. If not run again.

With it clean, type services into Cortana, Services Desk top app will appear at top. Click it. Scroll down the the Windows Update services. If it is running stop it. The Windows Update service must be stopped to manual install. Once stopped find your downloaded file and double click. Restart computer.

 

It been 12 hours since I upgraded from window 7 to 10 pro and installation is not finished yet.Please let me know when upgrade will be over?

 

What is currently on screen?

 

All it said for the last 12 hours is update and more update !!!

 

If you have been on one screen for 12 hours that says updating you are in a loop. Did you back up you data before you started the upgrade?
