[Total Security prevented me from installing Windows 10 version 1903]

Kaspersky Internet Security prevented Windows from updating to 1903. Access Denied' Similar strings to the above posted log in my log relating to Kaspersky.

Hello megabug7, Welcome!' Thanks for letting us know. Upgrading the operating system is significantly different to "updates". Standard best practice for major upgrades is to (temporarily) configure av to not start at system start up, disable av and or uninstall anti-virus software before proceeding with the upgrade. Thank you and best regards:pray_tone3:

Kaspersky didn't require any deactivation, uninstalling etc with Windows Feature update 1809 I spent the whole week trying all sorts - including having exited Kaspersky during the Windows update and even tried it in Safe Mode - An anti-virus application should NEVER prevent / interfere with the operating system updates - END of Discussion I won't be renewing my subscription next year

It really isn't the "end of discussion" as literally every anti virus application has had this issue at one time or another. To single out Kaspersky isn't fair, especially when you failed to follow standard practice during major OS upgrades.

Omg, so it's not just me?! I've been trying to contact Microsoft for 2 days now and I keep getting this error code: 0xC1900101 – 0x20017 Which means it's either something wrong with the drivers or the antirvirus, I'm pretty sure everything in my drivers is up to date, but I was suspecting it's this KTS! I really never was a fan of KTS, but when people suggested it, I wanted to see what the gest was about... and man do I regret it; because I've recently had my windows defender discovering a malware, that KTS did NOT!!!!!

What was the name of the malware detection that Windows Defender caught? If as you say Kaspersky didn't catch it, help the Kaspersky community out by submitting the malware sample to Kaspersky for analysis.

[Updated to KIS 2020 [20.0.14.1085(a) went flawlessly and kept all my settings from KIS 2019 without any issues as KIS 2020 installed directly over KIS 2019.]

Great to hear! I was tempted to go this route myself but decided to uninstall it and do a clean install. Either method is fine as long as the end result is the same. :relaxed: I just got patch C today for KTS 2020! :metal:

[KTS vs KSC [Solved][Closed]]

This is just my opinion and not meant to be a harsh criticism, but why does this question about "KTS vs KSC" keep coming up over and over and over again on the Kaspersky Community Forums? My take on this issue is that Kaspersky (as a whole) is simply not doing a good enough job at explaining the comparative differences between there own products. This is definitely not a good business model for Kaspersky or it's end users if these types of questions keep appearing on their own support forums. Let's get this addressed Kaspersky by providing clearer comparative differences between products so there is less confusion and more transparency among your products so we can obtain the correct product for our security needs! :slight_smile:
