Here is a fix I just verified from Microsoft resources and guaranteed it works.
First of all:
#1
In the Windows search,
Search for Windows Powershell, right-click it and choose run as administrator.
Next, execute this command:
set-executionpolicy remotesigned
Afterwards, select Yes to All when prompted. Keep the Window open.
#2
Download this script.
Make two folders on your C drive root, with names 1 and 2, so their paths are as follows:
C:\1
C:\2
Paste the script file you downloaded into folder 1.
In the Powershell window, navigate to the C drive folder and enter this command:
cd C:\1
This will ensure the folder which contains the script is selected. Now, we need to run the script, which increases the size of WinRE. For that, run the following command:
.\1.ps1
After that, press Y to confirm running the script.
When you are asked for the backup directory(this is used to ensure that your device remains bootable if anything goes wrong), enter
C:\2
Press Enter.
Wait till your PC restarts.
After that, if you check for updates, the update should install successfully.
Can someone else verify the method above worked? Just wanted an additional verification before running that script on my machines. Thanks.
