Freeing Disk Space on C:\ Windows Server 2008

 

I just spent the last little while trying to clear space on our servers in order to install .NET 4.5. Decided to post so my future self can find the information when I next have to do this.

I performed all the usual tasks:

  • Deleting any files/folders from C:\windows\temp and C:\Users\%UserName%\AppData\Local\Temp

  • Delete all EventViewer logs

    • Save to another Disk if you want to keep them

  • Remove any unused programs, e.g. Firefox

  • Remove anything in C:\inetpub\logs

  • Remove any file/folders C:\Windows\System32\LogFiles

  • Remove any file/folders from C:\Users\%UserName%\Downloads

  • Remove any file/folders able to be removed from C:\Users\%UserName%\Desktop

  • Remove any file/folders able to be removed from C:\Users\%UserName%\My Documents

  • Stop Windows Update service and remove all files/folders from C:\Windows\SoftwareDistribution

  • Deleting an Event Logs
  • Run COMPCLN.exe
  • Move the Virtual Memory file to another disk

However this wasn’t enough & I found the most space was cleared by using the Disk Cleanup tool “cleanmgr.exe” but of course this isn’t installed by default on Windows Server 2008. 


In order to get the Disk Cleanup you need to go to Server Manager > Add Features > and turn on “Desktop Experience”

After running the Disk Cleanup I found this gem “Hibernation File Cleaner” was using almost 7.45 GB, I’m pretty sure I don’t need Hibernate functionality on an always on Web Server.

This was a big win & I could continue installing .NET 4.5

3 Reasons Why Progressive Web Apps (PWAs) Won’t Replace Native Apps

Many people believe Progressive Web Apps (PWAs) are the future of the mobile web, but in my opinion, PWAs are not a replacement for native mobile apps. Here are three reasons why: 1. Native mobile apps provide a smoother & faster experience  Mobile websites, progressive or otherwise are slower and not as smooth. 90% of the time spent is spent using apps vs the browser . The single most significant contributing factor to a smooth experience on mobile is the speed of the network and latency of the data downloaded and uploaded. When you visit websites on desktop or mobile, there is a lot of third-party code/data that gets downloaded to your device, which more often than not has zero impact on the user experience. This includes: CSS (Cascading Style Sheets) JavaScript Ad network code Facebook tracking code Google tracking code The median number of requests a mobile website makes is a shocking  69 . On the other hand, native apps only get the data that is requi

Consuming the SSRS ReportExecutionService from a .NET Client

  I’ve just finished writing a nice wrapper which internally calls the SSRS ReportExecutionService to generate reports. Whilst it was fairly simple to implement there has been some major changes between 2005 and 2008 and the majority of online and documentation is based on the 2005 implementation. The most important change is that the Report Server and Report Manager are no longer hosted in IIS which will be a welcomed change to Sys Admins but makes the security model and hosting model vastly different. So far I’ve yet to figure out how to allow Anonymous Access, if anyone knows how to do this leave a comment and it will be most appreciated. Getting Started To get started you’ll want to add a service reference to http://localhost/ReportServer_SQL2008/ReportExecution2005.asmx where ReportServer_SQL2008 is the name you configure in the Reporting Services Configuration Manager. The Web Application files are located in C:\Program Files\Microsoft SQL Server\MSRS10.SQL2008\R
