For now, if you’ve already gotten the Windows 10 October Update, it’s best you check through your data to see if any files are missing. If there is indeed something missing, then it’s best to get in contact with the company directly. The Malaysian contact number is 1 800 81 8798, or you could talk to the virtual assistant on the support page here.
If you’ve manually downloaded the update, then it’s best to leave it alone or get rid of it until Microsoft rolls out a fixed version of the OS update. (Source: Microsoft)
