Build 10.0.586 Installation Error
I got a refurbished Dell Precision M6600 laptop a few months ago. I immediately (and successfully) updated it to Windows 10 from Windows 7 when I got it. (It did not come with backup media.)
However, once it had Windows 10, I had many problems updating it. With most update attempts, it would fail and revert changes.
My concern is the big November update, which would perpetually fail, with the following error code:
0xC1900101-0x30018
However, after one particular attempt, it never showed back up in Windows Update. I have the Media Creation Tool for build 586 on a flash drive, but every time I attempt it, it gives a simple 'update failed' popup saying to restart to retry the update at 40%.
I disabled my antivirus and firewall, and I switched off the Wifi for my most recent attempt. I'm fairly certain all my drivers are up to date.
I've probably attempted this eight times at this point, so it's not 'just a fluke', I assume.
Side note, my 6-year-old Dell Inspiron 1545 installed the new build fine.
I don't want to do a clean install (e.g., not keep apps) because I have far too many programs and games installed for it to be time-effective.
It installed today's regular updates fine; it just won't do the big update from build 240 to 586 (which, again, does not show up in the list).
I've seen other people post about issues with this update, but most of them seem to be upgrading from Win7 or 8, and they usually say they had a BSOD and had stopped at a lower percentage.
I would prefer to not take it apart, if possible.
Any help would be greatly appreciated.
