Hello,
I tried updating my windows10 but it gave me error 0x800703f. That's why my computer is so slow. I also noticed that there is no SysWOW64 file, even though my computer has a 64-byte operating system. All materials are in the System32 file. I tried many things but it didn't work. When I tried to reset I got the message that an error was encountered in the last step, so resetting will cancel.
Please help me solve this problem,
Thanks.

Click the link below, then click 'Update Now' on that page to download the Update Assistant, then run that to immediately get 21h1 and bring your PC right up to date
Thank you.
Even though I did what you said, it still gives the same error when updating.

I am Dave, I will help you with this, it would be very unusual for the SysWOW64 folder to not be in the Windows folder on a Windows 10 64bit system
1
Click your Start Button, type winver and hit EnterOn the resulting dialog, what Version No. and build No. of Windows 10 are you running?
3
Open the Settings App (gear icon on your Start Menu)Go to Update and Security - Windows Updates
What update(s) are showing as pending on your system?
Winver shows that Version 2004 (IS build 19041.1165).
Windows update shows 21H1 feature update and Cumulative Update for Windows 10 Version 2004 09 for 2021-x64-based Systems (KB5005565)
