Hide Installed Programs
by

Have you ever wanted to be sneaky and hide a program that’s installed on your computer from Programs and Features and the Apps & features list? Well search no more, I have all the answers you seek. It’s shockingly simple.

Proper programs will list their uninstall info directly in the registry all we have to do is tweak that slightly.

If the program is 64 bit it will show up in the registry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and it will have a key for it’s program sometimes listed by its program ID or the actual program. You may need to search for the application you want to hide.

If the program is 32 bit it will show up in the registry in HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall just like 64 bit it will have a key for the program.

The process is the exact same for 32 bit or 64 bit programs.

Default Gateway Layer 3
by

I’ve been playing with a Brocade ICX 6650 in router mode and got hung up on making the second VLAN on another Virtual Ethernet talk to the internet. I’m posting this so I don’t forget how to do it later on lol.

Your default VLAN of 1 is on Virtual Ethernet 1 and because that’s likely going to be on your regular network you likely won’t run into this issue. However when you make a second VLAN and you want things on that VLAN to be able to talk to the internet well the missing piece is an IP route for the default gateway so it knows how to get to the internet.

My setup looked like this

Nothing on VE 70 could talk to the internet.

ESXi Manual Update
by

You can upgrade your ESXi very easily with vCenter but if you don’t have that well then here is how you can do it manually.

With VMware the depot files contain the VIBs and image profiles (basically everything you need). You can read more about it here.

  • Upload the offline bundle into a datastore (make a note of the full filename)
  • Depending on your setup either migrate the VMs or turn them off

ESXi Config Backup
by

Backups are a good thing to have. While it can be super quick and easy to rebuild your ESXi config sometimes that is not always the case. It’s a good idea to have a backup just in case. Here’s how to do it.

  • Enable SSH by right clicking on the host and selecting Services > Enable Secure Shell
  • Login with SSH
  • Enter the following commands
vim-cmd hostsvc/firmware/sync_config
vim-cmd hostsvc/firmware/backup_config

Azure IP Downloader v1
by

My firewall recently blocked Microsoft Azure AD Connect which caused issues with syncing to 365. Turns out the issue was that my IPS (Intrusion Prevention System) flagged it as being “suspected RST injection”.

Normally when something like this happens it’s typically the IPS being overly sensitive and I usually can whitelist the specific detection however the IPS is blocking other things correctly that are also flagged as “suspected RST injection” because this is Microsoft Azure I can’t simply just whitelist the IP or a short IP range because there are so many and they can change fairly often.

Microsoft does list some of the IPs for most of 365 on their website however the IPs that were being blocked from my side of things was 52.239.186.132 and 52.239.149.106. Which aren’t in the main lists as they are part of the Azure side of things.

There’s a link on the same page that will take you to a download page for all the Azure IPs. However they update that file weekly. AWS publishes a JSON file of their IPs here.

It’s been years that people have asked for Microsoft to just publish the IPs in a JSON file like how AWS does. There’s a feedback request from 2016 asking for something like that here. Microsoft did make the JSON file available but in a roundabout way.
