Microsoft is blocking Windows 10 updates for some Avast and AVG Antivirus users


If you're looking to install either Windows 10 1903 or Windows 10 1909 (the May 2019 and the November 2019 updates) and you're a user of Avast or AVG Antivirus, you may well find that Microsoft prevents you from updating.
The company has identified a compatibility issue with the antivirus software and is therefore blocking the updates. Microsoft is also advising users not to try to sidestep the block by manually installing the update.
Windows 10 November 2019 Update is seriously small, but Microsoft says not to get used to it


When you download Windows 10 November 2019 Update (Windows 10 version 1909), you might be somewhat surprised at just how small it is.
At a ridiculous 180KB (yes, you did read that correctly) this is a tiny size for a feature update -- but it doesn't signal the way things are going to be moving forward. So how on earth did Microsoft manage to make this update so small? What's going on?
Windows 10 still has problems with the Start menu and search even after the KB4522355 update


The Start menu is at the heart of Windows 10, so any problems with it have serious repercussions. Included in Microsoft's recent batch of bug-riddled updates, however, there have been two -- KB4515384 and KB4524147 -- which have broken the Start menu in various ways.
Last week Microsoft released KB4522355 proclaiming that it fixed issues with both the Start menu and search. Only it didn't fix problems for everyone. Start menu problems remain, and some users are still unable to use the search facility.
Microsoft releases KB4522355 update for Windows 10, fixing Start menu problems and more


Microsoft has released a series of problematic updates in recent months. The company seems to be playing catch-up, pushing out patches for bugs caused by the last update, in turn introducing new problems.
With the newly released KB4522355 update, Microsoft says that it has fixed a number of issues -- including problems with the Start menu, the Cortana Search bar, Tray icons and Microsoft Edge -- that were caused by other recent updates.
KB4520062 update is breaking Microsoft Defender Advanced Threat Protection for some


Another update for Windows 10 is causing issues. This time around the update is KB4520062 for Windows 10 version 1809, and it was supposed to fix problems with Bluetooth and blank screens when it was released earlier this week.
But some users are finding that the update is breaking Microsoft Defender Advanced Threat Protection (ATP). Microsoft has acknowledged that the update can stop the anti-malware tool from running, and may also result in a 0xc0000409 error.
KB4517389 is causing even more problems with Windows 10 than first thought


That Microsoft's updates for Windows 10 have been problematic is hardly a revelation, but the scale of the problems just keeps on growing.
We have already written about numerous bug-ridden updates, including KB4517389 breaking the Start menu and Edge. Now this same update is being blamed for display issues and random BSODs.
You won't be surprised to learn that yet another update is causing Windows 10 problems

KB4517211 update is breaking search and VMWare Workstation in Windows 10


Microsoft has had an appalling run of problematic Windows 10 updates recently, and the spate of dodgy patches shows no signs of letting up.
With the recently released KB4517211 update, users are now reporting problems using Windows 10's search function, as well as finding that the update is preventing VMWare Workstation from launching.
Another Windows 10 update is causing problems, this time with printing


There have been a series of problematic updates for Windows recently, and now yet another one has popped up, this time affecting not only Windows 10, but also Windows 8.1, Windows 7 and Windows Server.
The KB4522016 cumulative update is interfering with printing. The update is causing issues with the printer spooler service, leading to print jobs failing or being canceled without user intervention.
Microsoft is working to address high CPU usage and search problems with KB4512941 update


A week after its release, Microsoft says it is working to fix a problem with the KB4512941 update for Windows 10. Users have complained of a spike in CPU usage by SearchUI.exe and said that search results are blank.
The company had been slow to recognize that there was a problem, but it did eventually acknowledge the issue on Twitter. Now Microsoft has provided more details about its work on a fix which is due for release later this month.
Windows 10 KB4512941 causes high CPU usage by Cortana [UPDATED: Microsoft is working on it]


Following the release of KB4512941 for Windows 10 version 1903, users have noticed a huge leap in CPU usage by Cortana.
After installing the cumulative update, the Cortana process SearchUI.exe is making much higher use of the CPU for many people. The problem can arise on systems where Bing Search has been disabled, and a series of workarounds have been suggested while Microsoft works on addressing the problem.
Microsoft will block the Windows 10 May 2019 Update if you have a USB drive or SD card connected


If you have external storage attached to your computer, you may well find that you're unable to install the Windows 10 May 2019 Update when it is released next month.
Out of an apparent abundance of precaution, Microsoft is opting to block the installation of the update if a computer has an external USB drive or SD card plugged in. The block is being introduced because of fears that drive letters might be inappropriately reassigned during the installation.
April's Patch Tuesday updates are causing Windows to freeze or slow down


If you installed the latest batch of patches from Microsoft this week and found that your computer started to freeze up or fail to boot, you are not alone.
The problem is affecting Windows 7, Windows 8.1, Windows Server 2012 and Windows Server 2012 R2, and stems from a compatibility issue with antivirus software. Users with antivirus tools from Avast, Avira and Sophos have experienced problems -- including slowing down Windows 10 -- and Microsoft has blocked the rollout of updates to some systems to try to limit the damage.
Windows 10 will automatically uninstall problematic updates


Updates to Windows are supposed to fix problems and improve security, but sometimes they do the opposite. Many Windows 10 users will have experienced startup problems after installing an update to the operating system, and this is something that Microsoft is looking to address.
Rather than leaving it down to users to seek out the problematic update and uninstall it, Windows 10 could start to automatically uninstall updates that have caused issues. If this happens to you, you'll be greeted by the message: "We removed some recently installed updates to recover your device from a startup failure."
From July, Windows 7 and Windows Server 2008 users will need SHA-2 support to get updates


Microsoft has announced that from the middle of July, Windows 7 and Windows Server 2008 users who want to continue to receive updates will need SHA-2 code signing support.
The change is being introduced because "the security of the SHA-1 hash algorithm has become less secure over time due to weaknesses found in the algorithm, increased processor performance, and the advent of cloud computing".
