Hello. Yesterday i had updated my win 10 and i just clicked "update and shutdown the pc". Today i wanted to run game CS:GO but i still get blue screen and it tells me that "portcls.sys" failed. What can i do to fix this problem. I checked game files and it was 3 problems that automatically repaired and still nothing changed. Thanks.
Well as you know these problems with 1903/1909 have been going on since the previous questions from last month : Cumulative Updates - March 10th 2020 . I had decided to let my Laptop be updated at the latter part of February to 1909, however it kept failing. I was advised in community to let my 1809 get up to date & try again, so I waited till March's Patch Tuesday but I got offered no updates through WU, hence that's how I cam across in the community Cumulative Updates - March 10th 2020 . with 1903/1909. I also found that I had not been offered any updates through WU for February 25th. Everything was working fine until the failed 1909 upgrade. With the number of 1903/1909 users that we having issues in the 19 pages of Cumulative Updates - March 10th 2020 . I was glad I didn't get the upgrade and thought I'd wait for it to be sorted on April 14th as even if I did a clean install the build would be the same as that everyone was reporting issues with.
So I was hoping to see the LCU on April 14th sort the issues out, seems not so. However what happened in my case is no LCU for 1809, just a forced download of 1909, ……..it got to 100% "Getting things ready" and yet failed twice again, I haven't logged off since incase it trys to install b ut there is no download in SoftwareDistribution, and like others have reported "unable to complete ".
So as I had a stable system prior to the 1909 failed download in February and Microsoft have extended the end of service date, staying with 1809 is the less risky option as end of service now 7 months away, I can't afford to not have my laptop for one day in the present lockdown.
Pausing Updates isn't a problem in 1809 but requires wuauserv to be running. The forced download of 1909 on April 14th also deleted my "Update History". So I only know what LCU's I'm missing the build number I'm at currently.
After this update, my pc cannot connect to the internet.
I can see the wifi adapter in the device manager and there are no problems reported. No available networks show to connect too.
The troubleshooter tries to fix the problem but it cant. I have tried possible solutions I found online and till have the same problem.
Please help!
Is it time to find a way to block all windows updates forever?
Hello!
I have an MSI and yesterday after many many notifications that my device requires an update I finally gave in and clicked on Update Now. Everything went fine until my laptop restarted and I was hit with the infamous blue screen ( YOUR DEVICE RAN INTO A PROBLEM AND NEEDS TO.....) with each time a different stop code ( here are some I managed to remember MEMORY_MANAGEMENT/ DPC_WATCHDOG_VIOLATION). Then I was hit with the IT LOOKS LIKE WINDOWS DIDN'T LOAD CORRECTLY and I was left with the choice SEE REPAIR OPTIONS or RESTART MY PC. Now I know after various attempts that restarting my laptop doesn't solve it. So I clicked SEE REPAIR OPTIONS > TROUBLESHOOT > RESET THIS PC > REMOVE EVERYTHING. That didn't work as well basically everything I tried didn't work, a restore point, uninstalling update, reset to MSI factory, startup repair,... I tried contacting the support center but the virtual assistant was obviously no help at all. Was looking for a way to contact via e-mail however I couldn't find one for them. I somehow found a number that I will be calling tomorrow. I really need help, I don't understand much of what's happening and how I can possibly fix it. Here are some more info about my device and windows product.
