How to Fix Windows 10 Upgrade Stuck at 99%?
“My Windows 10 upgrade Assistant application can download verified and authentic updates but gets stuck at 99% at times. Is this normal? What should I do hereafter?”
Lately, these are the common queries that are flooding most the communities and Microsoft forums.
If you are one of them, then welcome to our website.
Today, we are about to discuss this very same issue.
We have been hearing from many users, that Windows 10 upgrade gets stuck either at 99% or 0%. Getting stuck at 99% is most commonly encountered.
Microsoft recommends users to wait to check if the upgrade process completes or not. Sometimes it takes time to complete. And you have to be patient about it.
But if the update is taking more than a few hours on a stretch, then you seriously need to take some action.
Here are some few quick fixes for this pesky issue.
Solution #1: Update Missing Drivers
The problem you are currently facing might be due to some missing drivers. Thus before upgrading you must update the missing drivers first.
Follow the steps to do that:
Step 1. Press “Win + R” to bring the “Run” search box. Enter “devmgmt.msc” and press “Ok”.
Step 2. This will open up the device manager operating Window.
Step 3. Now here check for any missing driver. Expand the categories one by one and see if there is any yellow mark or not. An exclamation sign would also come with it. This indicates that the driver needs to be updated.
So download the driver from the manufacturer’s website or let the computer search for the compatible version online.
Solution #2: Fix the Issue using $GetCurrent Folder
$GetCurrent folder is a hidden folder created in the root directory of the C:/ drive during the upgrade process.
It usually contains the last Windows installation log files. These files are quite large, nearly about 3-4 GB. These leftover files may at times causes this stuck at 99% issue to arise.
A simple modification within the folder can root out the issue once and for all.
This is how you do it:
Step 1. Restart your computer.
Step 2. Go down the following pathway in the system drive: Tools> Folder Options.
Step 3. Under the “View” tab, check the “Show hidden files, folder or drives” checkbox.
Step 4. Now search for “$GetCurrent” folder form the C: drive and within the folder rename the second folder as “media”. Within the folder, you can still find a regular Windows 10 creator update edition package.
Install this edition normally, and most probably that will resolve the problem for now.
Solution #3: Clear Update Cache in Safe Mode Manually
When the update cache files get accumulated in huge number is bound to arise. So we will first enter the computer in Safe mode, which suspends many third-party tools and unnecessary applications keeping active only the basic services.
This way, you get a clear opportunity to work out the issue when everything else is subdued for a while.
Here is how you do it:
Step 1. Hold the “Shift” key as you click the power button and restart in Windows 10.
Step 2. Next, go to “Troubleshoot” option.
Step 3. Choose “Advanced Options”.
Step 4, Next select “Windows Startup Settings”, then “Restart” and finally “Safe Mode”.
Step 5. Press “Win + X” key combination. Choose “Command Prompt (Admin) from the search result.
Step 6. As soon as the black dialog box pops up, enter the following command and hit “Enter”.
net stop wuauserv
net stop bits
Step 7. Next navigate the following pathway within the file explorer:
Step 8. Delete all the content files within the “SoftwareDistribution” folder.
Step 9. Now reopen the command prompt and again and type the following command and hit “Enter” after each command:
net start wuauserv
net start bits
This will simply restart the Windows update service.
Step 10. Now reboot your computer and try to run the Windows updater this time.
This time, fortunately, you will not have to see the same old issue most probably.
Apart from trying out these methods, make sure that you have disconnected all the non-essential peripheral devices, like a flash drive, smart card readers, etc and have unplugged all hard drives except the C: drive.
If possible, try to turn off Wi-fi and connect using LAN cable. It worked for me, may work for you as well…… Who knows?!@
But if you still have some doubts, and nothing seems to work in your favor, consult immediately a technician.
