How much free space does Windows really need to be performant?
in flag

We have a virtualized file server here whose data resides on a SAN - performance through the SAN is plentiful.
But now the 2TB disk on the virtualized Windows 2012R2 file server is almost full since several weeks (30GB Free) and we discuss internally how much free space Windows really needs to be performant.
For ages there has been a recommendation that NTFS needs about 10% free space - can this be measur ...

Updated VirtIO SCSI driver on my Windows 2012 R2, and now only boots into recovery. How to recover?
us flag

I have a Hetzner W2012 R2 Cloud VM, and I updated the VirtIO vioscsi driver on it. Now it only boots into recovery mode and I cannot access the C-drive even from command prompt.

Is there any way to save this VM or is it a goner?
I have no (recent) snapshot of it :(

I can mount the old previous VirtIO ISO, but how can I reinstall the old driver when I have no access to the C-drive?

WSUS drivers supersedence
tn flag

I have added the driver classification in wsus and now i have 100k driver updates. The supersedence is not specified so i can't easily decline old updates. I see a lot of duplicate versions for the drivers (update id is different so it's not the same update).

In the past this was bad but since i added windows 10 it's almost unmanageble.

Hopefully the title covers this question but, it's pretty straightforward.

At work, we have an old DMZ Server we'd like to replace with a newer model. Unfortunately, when we were ready for the swap, the NIC didn't light up (no link lights). So we plugged in the old DMZ Server and link lights to that server were re-established.

I've finally virtualized our entire server infrastructure and I'm ready to start migrating to our bought Windows server 2019. Since our current setup is based on Windows Server 2003 we obviously have to do the migration step via an interim installation of say 2012 R2 (AFAIK 2016 would be ok too).
