Sometimes, if you can't use the graphical Event Viewer (e.g. on Windows Server Core), it is handy to list the latest Event Viewer entries via Powershell:
Get-EventLog System -Newest 10 | fl
Get-EventLog Application -Newest 10 | fl
This is also much quicker than starting Event Viewer.
After the September 2021 Windows Update, non-administrator users will no longer be able to add remote printers without an elevation of privilege to administrator.
To allow normal users to add remote printers (hosted on a print server), you can now add the following Registry value on the client:
RestrictDriverInstallationToAdministrators = 0 (DWORD 32)
No restart of the client is needed.

When logged in as Administrator in a Windows 10 or 11 machine, when you try to add a shared printer, you get the error:
That didn't work. We can't install this printer right now. Try again later or contact your network administrator for help. Error: #740.
The underlying problem is this: Error 740 means: "The requested operation requires elevation".
This is a problem as you are already logged in as Administrator. So the solution is to start the "Add Printer Wizard" as Administrator. To do this:

Somethimes, the default maximum message size (including attachments) is not enough (30 MB is the standard). To increase this to 100 MB, do the following:
First check the current maximum size on all relevant Exchange components:
Get-TransportConfig | ft MaxSendSize, MaxReceiveSize
Get-ReceiveConnector | ft Name, MaxmessageSize
Get-SendConnector | ft Name, MaxMessageSize
Get-Mailbox Administrator |ft Name, MaxsendSize, MaxReceiveSize
Then set it to 100 MB for all components:

Happens only on the primary screen
Only when application is maximised
Only some applications are affected, not all (Microsoft Office apps are never affected): File Explorer, Edge, Firefox, Notepad and many others
What does not help:

Unfortunately, Adobe is pushing hard to their Cloud Suite (Creative Cloud) and has disabled all download links to their CS6 suite. After some searching, I found the following 2 links still working (as of May 2020):

On an IIS server, with a simple static web page, I constantly got:
HTTP Error 503. The service is unavailable
I did not get any entry in the IIS logs and when stopping the respective app pool, I got the same message.
There was definitely no port conflict as I checked with TCPView if any other process was using port 80.
After a while I tried to change the binding to port 81. And - bingo - , on port 81, the web site worked.
After digging for a while, I found that port 80 had an "ACL reservation". Read more [...]
If you have clicked on a Symbolic Link (SymLink) in Windows and got the following error message:
"The symbolic link cannot be followed, because its type is disabled"
You can check what SymLink Types are allowed by using the following command:
fsutil behavior query SymlinkEvaluation
If you need to change this, so you don't get the error, you can run:
fsutil behavior set SymlinkEvaluation R2R:1 R2L:1
With the onboard tools of Windows, you can only create symbolic links with the command line (unless you download some third-party GUI tool). The syntax is as follows:
mklink /D "c:\inetpub\External" "\\server\share"
This will create a folder c:\inetpub\External and it will point to a share on a server. You can delete c:\inetpub\External via normal File Explorer, it will only delete the Symbolic Link, not the destination share.
On Windows Server 2019, I wanted to switch off Windows Defender Anti-Virus realtime scanning to test something. I went to "Windows Security" and then cliecked on the "Open Windows Security" button. This brought up the following error message:
You need a new app to open this windowsdefender
After some searching, I found that you need to install the missing app yourself, it seems to be a bug in Windows Server 2019. To do this, open Powershell as Administrator and type (all in one line):
Add-AppxPackage Read more [...]
