Installing Windows 11 on older hardware (no TPM2) and installing Ubuntu WSL2 with ZSH in it

Create Windows 11 media with Microsoft’s media creation kit.
Image the resulting ISO-file to an USB stick with e.g. Rufus.

Create bypass.reg.
———————————————
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig]
„BypassTPMCheck“=dword:00000001
„BypassSecureBootCheck“=dword:00000001
„BypassRAMCheck“=dword:00000001
„BypassStorageCheck“=dword:00000001
„BypassCPUCheck“=dword:00000001
———————————————

Copy bypass.reg to the stick.

Install Windows 11
In Setup hit shift-f10 to enter a cmd prompt
There startup notepad.exe
Use the open dialog from Notepad to navigate to the stick.
Change file types to all and right-click on the bypass.reg.
Choose merge.

Now continue to install Windows 11

After installation login with wrong credentials intentionally.
So you will get the option to use a local user only.

Where you can choose now within the OOBE setup.

Check if your Windows edition is the right one.
Maybe change in Windows settings.
Note: You might need a corresponding product key and valid license to do so.

Download and install Brave.
Download and install OpenVPN.

After finishing the setup, open up an Explorer and set options to:
– show extensions
– show hidden files and system files
– startup with This Computer
– do now show recent files
– clear recent file

Download W11ClassicMenu1.1 and start it up.
When SmartScreen is complaining – click on more information – then choose run anyway.
Then reactivate „classic context menu“.

Install chocolatey.
Open up an admin powershell and paste
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString(‚https://community.chocolatey.org/install.ps1‘))

Install some software.

wsl –install
Note: This seems pretty easy under Windows 11. Saw also installation of GUI support with this installation command. Will try if it can display X application.
After wsl –install finished please reboot the system.

The system will come up with the Ubuntu installation dialog after login automaticalls.
It sets also the WSL version to 2:
wsl –list -v

Performance Probleme durch Hardware Interrupts Windows 2003 in VMware ESX 5.5

Bei einem Server für ein Dienstplanungsprogramm stellte sich vor einigen Tagen ein massives Performance Problem ein. Ich vermute, dass jemand etwas an der virtuellen Hardware durchgeführt hat. Konnte aber keine weiteren Informationen dazu erhalten. Vielleicht gab es ein VMware-Tools Update etc. Leider konnte ich mich aus Zeitgründen nicht weiter damit befassen, da es für mich für nur noch um die Lösung des Problems ging.

Auffällig war, dass die Datenträgerwarteschlange im Perfomance Monitor von Windows sehr hoch war.

Weiter fiel mir auf, dass der Taskmanager permanent 100% CPU Last anzeigte, jedoch die Addition der CPU-Last der laufenden Prozesse max. auf 80% CPU-Last kamen.

Darauf hin habe ich mir die Sache mit dem Process Explorer angesehen.
