Users Complain about Slower Windows after April 2019 Updates
TEHRAN (Tasnim) – Microsoft Windows 10 Users are complaining that Windows has suddenly become slower and programs are taking much longer to open after installing this week's Microsoft's April 2019 Patch Tuesday updates.
Recently, it was reported that there is a conflict between the latest Windows updates and Sophos, Avast, and Avira antivirus software that is causing Windows to freeze or updates to not finish installing.
Since then, reports were seen from users who have stated that this week's updates are also causing Windows to become very slow. The reports have been from users running Windows 7 and Windows 10.
The issues that users are experiencing include Windows taking a long time to start or reboot, unable to start programs, lag in games, excessive disk activity, video streaming issues, and other similar problems, Bleeping Computer reported.
For example, in a comment at BleepingComputer a reader has stated that their Windows 10 computer has become extremely slow and that rebooting/starting Windows takes forever.
" I have Windows 10 & it’s done it to my computer. It is extremely slow. It shuts itself down. It takes forever to restart or reboot. Sometimes it can’t. I ran a long check on it in setup options. It said it found no errors. It said press enter to restart. I got a notice stating it could not be started because there was a problem with windows 10. They suggested I do a repair by returning it to Windows 7. I hit alt control delete & this time 10 loaded but it’s still extremely slow! I use Norton & not the programs listed."
Users on Reddit and elsewhere are also complaining that Windows has become very slow since installing the updates.
Normally when a user has an antivirus program, Windows defender will disable its real time protection. It seem for this user at least, Windows Defender is being enabled automatically even though the user had Avira installed on the machine.
Having two antivirus programs performing real-time protection could definitely cause slowdowns and other issues.
At this time there is nothing from Microsoft that states they are aware of the reported issues. The only reference to Windows being slow since the updates is from a support article posted yesterday by Avira that is simply titled "Why does my system run very slow?".
This article states that if Windows 10 has become slow, you should remove the KB4493509 update. For Windows 7 users, they state that you should remove KB4493472 and KB4493448 updates for Windows 7.
As these instructions are for users of their software, it may not apply to everyone.
BleepingComputer has contacted Microsoft to see if they are aware of these issues, but have not heard back as of yet.
