Basic commands (db2level) not running on no cost Db2 Community Edition 11.5.5 (latest)

The previous DB2 Express-C versions were working fine over the years, but the basic commands not running on no cost Db2 Community Edition 11.5.5 (latest) .
after installing the Db2 Community Edition 11.5.5, when running the db2level command, it gives the error:
SQL1022C There is not enough memory available to process the command.
and below links didn't help:
https://www.ibm.com/support/pages/error-sql1022c-there-not-enough-memory-available-process-command-after-changing-hostname-db2-server
https://www.ibm.com/support/pages/running-db2level-db2-command-window-returning-sql1022c
Some my findings are:
db2set' not working - DBI1302E Invalid parameter detected.
'db2set -all' working - DB2_EXTSECURITY=YES
'db2level' - SQL1022C There is not enough memory available to process the command.
'db2start' not working - SQL1390C The environment variable DB2INSTANCE is not defined or is invalid.
DB2 icon not presented on taskbar
db2 get dbm cfg | find "SYSADM" - not working (no output)
db2 get dbm cfg - DB21018E A system error occurred. The command line processor could not continue processing.
db2 update dbm cfg using sysadm_group DB2ADMNS - DB21018E A system error occurred. The command line processor could not continue processing.
Followed the same recommended steps (for DB2 installation) as being following since DB2 9.7 version (on WIN 8.1 machine + RAM 8 GB).
My logged-in user is machine administrator
The supplied user is 'db2admin'
Now on the problem machine, OS is Windows 10 Pro + RAM 8 GB.
Ran the setup.exe after extracting the downloaded zip
From the DB2 Setup Launchpad > Install a Product > DB2 Version 11.5.5.0 Server Editions > Install Now > then installed with all default settings
DB2 setup installed successfully but DB2 commands not working as explained above
I had the same issue but after installing db2 with administrator privileges (starting setup.exe as an admin) the issues were gone and everything was set up as expected.

MongoDb loses performance in Windows Server 2012

I am running an application how reads and write a batch process using MongoDb in 2 identical machines. One running Windows 8.1 and the other running Windows Server 2012.
The MongoDb performance in the Windows Server 2012 machine is 5 times worse than Windows 8.
Both machines have 16Gb of RAM, but the mongod.exe process consumes 1.2Gb RAM in Windows 8 and 500Mb in Windows server in an identical local database.
I already use MongoDb 2.4, 2.6 and 2.6 legacy and de behavior is the same.
Has anyone seen this behavior before?

Postgresql ODBC driver 32 bit

I need a help in postgres odbc driver setup. I have a Windows 2008 R2 server machine. I have SSRS running on this machine which is 32 bit.I need to install postgres odbc in the machine. Initially I installed a 64 bit Postgres odbc and I got the error saying that there is a mismatch between the driver and the application. Hence I downloaded a 32 bit driver in the machine. I tried to set it up through DSN but I could not find the Odbc driver in
the configuration section.How do I set up a 32 bit odbc driver in a 64 bit machine.
Start->Run
%SYSTEMROOT%\SysWow64\odbcad32.exe
In newer Windows versions there's an "ODBC Administrator (32-bit)" Start menu entry for it.
