I suppose it can be the known Bug 5657225: [SUPPORT] Mouse and keyboard does not work after reboot (patch i appliance)
It is related to our filters, which write in registry its values - only Windows OS can be affected. In most cases there was desinfection procedure + patch appliance. The problem will be fixed in next product`s version.
Here are the list of steps, which can help to resolve the problem(highest workaround is easiest one):
USB Recover tool is based on KRD18(Linux OS), so keyboard and mouse must work within BIOS and this OS, because they are not related to Windows and its registry filters.
The last one - is the hardest way to restore keyboard and mouse and it is better to do not use it, if you are not Advanced user of PC(skills of work with Windows registry is required).
Thanks.
P.S. We have had the problem with keyboard and mouse filters before(in 2016 and after), but it were single cases, which were related to kavremover utility, improperly installation/uninstallation of Kaspersky products, customer`s registry problems etc.

Hello,
I suppose it can be the known Bug 5657225: [SUPPORT] Mouse and keyboard does not work after reboot (patch i appliance)
It is related to our filters, which write in registry its values - only Windows OS can be affected. In most cases there was desinfection procedure + patch appliance. The problem will be fixed in next product`s version.
Here are the list of steps, which can help to resolve the problem(highest workaround is easiest one):
1. Use USB-Recover tool:
https://support.kaspersky.com/14221
to restore default mouse/keyboard filters values.
USB Recover tool is based on KRD18(Linux OS), so keyboard and mouse must work within BIOS and this OS, because they are not related to Windows and its registry filters.
2. Use System Restore. It can be run from Recovery mode:
https://www.ubackup.com/backup-restore/windows-10-recovery-mode-1021.html
Also you can run command prompt from this mode and delete keyboard and mouse filters manually:
3. Or manually delete Kaspersky values from registry:
Reboot PC - Troubleshooting - CMD - open regedit -
delete klkbdflt and klmouflt values in UpperFilters from the following path
HKEY_LOCAL_MACHINE\SYSTEM1\ControlSet001\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318}
HKEY_LOCAL_MACHINE\SYSTEM1\ControlSet001\Control\Class\{4d36e96f-e325-11ce-bfc1-08002be10318}
The last one - is the hardest way to restore keyboard and mouse and it is better to do not use it, if you are not Advanced user of PC(skills of work with Windows registry is required).
Thanks.
