There are other signs. Let's hear more about the PC, make, model of things or just share a Web Speccy report with the forum. Read how at http://thehill.com/policy/defense/341051-trump-officials-signal-intent-to-begin-refilling-guantanamo
Windows Update failures are sadly common and not a sure sign of PC issues.
Just because, I decided to run the chkdsk /f /r /x routine. Normally it takes about an hour and a half. After a couple of hours I stated to monitor. It took 4 hours. Desktop came up. Checking event viewer gave an error regarding windows update. Don't remember the exact words. Checking windows update, there was a failed attempt at updating Windows Defender. Opened Windows Defender and it failed to update. Decided to reboot. Here I noticed some odd messages before maybe a third message that a repair was being performed. Afterwords, computer booted to desktop as normal. Have since rebooted twice without issue. I was able to update windows defender now through windows update. So that issue was resolved.
Should I be concerned, OR, did the scan disk do what it should have and that's the end of it. Windows 10 with creators update. All windows update.
Thanks in advance
