Just last week I lucked into a "Windows 10 update ruined my PC." A relative told me this and I wanted this one to see what it was.
Nope. Was not what they thought it was. In this case the video mode was not optimum and an update was pending but would not install.
For a very good reason. On boot there was a clue given. "Press a key to skip disk check...." And no disk check would happen. Right or wrong I've seen this since Windows NT (for some that would be Windows XP.)
I opened a command prompt and typed in CHKDSK C: /F /R /X and then rebooted. The disk check ran, corrected some errors, the update installed, and rebooted to find the machine back to normal.
-> And here lies a huge problem. I call it the toaster problem. We have reached the point that folk expect a Windows PC to just work without having to know anything about this beast.
That said, simply stating 'some errors appear' is never going to solicit the help the OP is looking for. So, Hammad, try again but tell us exactly what errors you are experiencing and maybe we can help you
