Are you planning to install or upgrade Windows Server but unsure about the Windows Server hardware requirements? This guide breaks down the essential specifications for different versions of Windows Server, from 2016 to the latest Windows Server 2025.

GUI vs. Core Installation

GUI: Needs 2x RAM/CPU for desktop experience.
Core: Saves 50% resources – ideal for remote servers.

Future-Proofing

2025 Tip: Reserve 25% extra storage for updates.
Scalability: Use Windows Server 2025 Standard for growing businesses.

I always go to Indigo SoftwRe for my Microsoft Office purchases, I haven't found a better price anywhere. What I didn't know is that they have awesome customer service. I had an issue with my computer and needed to... reinstall my software. I wasn't sure how to do that so I reached out to Indigo. They quickly responded with a video which provided a simple solution. I was back to work in minutes. Thank you Indigo for simplifying my life!read more

I needed the Microsoft Office program on my Mac. When I purchased Indigo's product, I had several issues downloading and installing the program. However, when I reached out to the good people at Indigo, they went... above and beyond in helping me through all the steps needed in order to get the program up and running. I am beyond pleased with their expertise, knowledge, and the constant reaching out to me during the process! I've not seen a company care so much about their customers. Refreshing to see such professionalism! I would definitely recommend them for their products and services! Five stars to Indigo!read more

I’m thankful I found Indigo Software. Over the last few years, I’ve purchased their Microsoft Office Professional software suite for three different home computers. I don't understand why everyone does not purchase... their Microsoft Office programs thru Indigo Software. They are economical and provide great, responsive Customer Service!read more

I purchased a couple of licenses for Windows 10 over the years and 1 license for Office Pro 2019. I dumped one of my older laptops where Office Pro 2019 was installed and purchased a new laptop. Unfortunately, I... could not activate the Office Pro 2019 on my new laptop. I reached out to Indigo and they provided me a new legitimate activation code which I successfully registered in my Microsoft online account. I was then able to re-install on my new laptop without issue and fully activated and recognized as legitimate MS software.read more

They have amazing customer service. I accidentally ordered the wrong item and then email them about my mistake. They were very quick to cancel my original order and refund the cost so I could easily order what I... actually wanted. The refund credited quickly to my credit card so there was no financial impact or delay.They have an excellent video to a company the order which made it very simple and easy to download and install.I am so happy to see that there are companies out there that still know what true customer service is.read more

I purchased Office from Indigo some time ago, but in the aftermath of upgrading my PC's CPU and upgrading to Windows 11, the license was lost/deleted/corrupted/removed and my Office was deemed an unlicensed copy (with... the corresponding warnings from Microsoft.) The Team Indigo Helpdesk was (unlike some other "helpdesks") very helpful, resolving my issues promptly, even on a weekend. One may purchase productivity software from many sources, but they stand behind their service. Thank you Indigo. I feel comfortable in recommending your service to anyone at any time.read more

I've dealt with several software vendors in the past, but I can truly say that Indigo has exceeded my expectations. Not only are the prices fantastic (for LEGITIMATE Sftwr and Keys), but the response, and follow-up are... amazing. I purchased software on behalf of a non-profit, and they handled the tax-exempt status without any issue. Then when I bought Software for myself, somehow my email was 'linked' to that non-profit entity. Indigo responded incredibly fast and cleared it up. All this, while providing valid keys which activated without issue.I'm very happy with Indigo Software and will continue to use them as a valuable Software resource!read more

I am a Veteran disabled from a stroke , and built a New pc as therapy for my hand from components given to me as a gift, however I was having issues with my fresh new windows 10 Pro. Install and activation, 2 days... working on the issue ,and After hours on the phone with Microsoft support ,even they could not Resolve the Issue. I came upon the Indigo software website by accident. And thought I would send an email with my dilemma. It was late here on the east coast. I was very surprised in less than 1 hour I had received an email. With some instructions as to what I should look for. Emailed back a few screenshots of the errors. And 2 emails later. Within 1 hour . I was fully up and running. Issue was resolved. Not sure if I should mention a name, but I want to thank Michael of the Team Indigo Software Helpdesk ,,and company for resolving the issue. I highly recommend Indigo software for your Microsoft software needs. And their support is beyond fantastic. Please. Support this company. You cannot go wrong.Veteran owned business.Semper FiNeal Newmanread more

I purchased MS Office 2019 for my new computer in 2021. The Install went well and all was good. A little over a year later Outlook stopped being able to sign into the Comcast email. Talking to Comcast tech after several... different trials we found by deleting the Comcast account and reinstalling it fixed the problem. About a month later the problem happen again. The delete and recreate the account trick did not work. Comcast indicated it was a MS Outlook problem since my iPhone that uses the same interface and the webmail portal all worked with the account. I then contacted Indigo about the issue. I got an email the next day asking for the order #. A few days later a email with YouTube video links on how to setup the Office software. I replied with a second more in depth description of what had been tried to resolve the issue. I have not heard from them in a week now. I can't imagine someone dealing with this lack of responce if their business depended upon it. Fortunetly for me, it is just for home use. The problem may not be MS Outlook, but you have to be able to get the support / knowledgebase to work thru to the solution.Edit: As soon as I checked my email, Indego had responded with a proceedure to reinstall Office and make sure no other office products were installed. It worked and Office is resyncing with the email account now.read more
