When I get a PC with Win10 installed, I replace it with Win7

Though I have a hard drive dual-booted with 7 & 10, I primarily use 7. I only use 10 when it comes time to test it out on issues like what's being discussed here.

Among the many abilities 1803 provide is a SetupDiag is a new command-line tool that can help diagnose why a Windows 10 update failed. Also,

Privacy

In the Feedback and Settings page under Privacy Settings you can now delete the diagnostic data your device has sent to Microsoft. You can also view this diagnostic data using the Diagnostic Data Viewer app.

My two windows 10 computers updated with no problem. I only use the anti-virus that windows 10 comes with.

Would you do a clean install of Windows 10 by now. Via the free USB flash drive download that Microsoft provides?

Same here. The built-in A/V is entirely adequate for what I do.

I just did an archival disk-image of my existing system, and then downloaded the latest and greatest 1803 .ISO direct from Microsoft, installed it fresh (re-format), re-installed my apps, re-customized my settings. Didn't take long, and no issues.

I strongly believe that a complete re-install every year or two has numerous benefits:

• Reminds me of every application I really need, its licensing (if any)
• Gives me a chance to jettison old applications I don't need any more
• Removes nagging doubts about where problems are coming from (when they occur)
• Removes stale buildup of cruft, loose particles, and grimy film (or is that my teeth?)

The only downside is having to re-install apps and customize my settings again, but that typically only takes 20 minutes, and I always learn something new in the process. There are often new or updated features I wouldn't have looked for otherwise.

A lot like taking a shower after a day of hot, sweaty work, and slipping into clean, cool clothes. It's a wonderful feeling!

Since the update, Windows blanks the screen randomly then resets it

> Since the update, Windows blanks the screen randomly then resets it

That suggests a video driver issue. Depending on what your video hardware is, you might check the vendor's website and see if they have a fix for that.

If it's not that, and it really is Windows itself doing it, a google search might turn up something in a little while, after more users start reporting it. Good luck!

Thanks! Do you agreer that a fresh install of Windows 10 1803 will work smoother than an old Windows 10 install that has been updated to death to reach the 1803 level? It seems to me that a one hundred updates and patches make for some confused code so you computer does not run as well.

ALSO>>>>>> Did you you have to enter your windows 10 key or is it in the BIOS-UEFI so is automatic?

Yes I agree, that's what I do for major updates. Incremental updates (Patch Tuesday, or the sneaky out-of-cycle ones) I don't worry about. But when the "update" is IN FACT a pretty much complete over-write, I figure it's better to just start fresh with the .ISO and install from scratch.

It might depend on your system, but in my case I had to enter the Win10 key during the install.

WINDOWS UPDATE CHECKLIST >>>>> FOR INSTALLING BIG APRIL 2018 UPDATE

3 Weeks Ago #2

The error code 0xC1900101 is very common and indicates that a rollback occurred. Most often this is due to a driver but there are many other causes.

When upgrades are performed they can be done with the upgrade assistant or with a Windows 10 iso. Using a Windows 10 iso will create another error code which is the extend code. This information can help narrow down the underlying problem.

Run through this upgrade check list.

UPGRADE CHECK LIST:
Run through this check list before the next upgrade attempt:

1) remove nonessential hardware
docks
USB devices

5) update windows (have all recommended updates installed) and reboot after updates

6) uninstall all non-Microsoft antivirus software
(This includes always on and manual software.)

7) Verify that the drive has > 27 GB free space (At least 25 GB is needed for creating dumps)
