Yeah, I have about 30 gigs of apps and data (seems kind of large for a boot drive, but yeah)Correct me if I'm wrong, but ... 128GB, take away 62GB, leaves... more than 1.2GB.
So, are you saying, your Windows directory is that large, but yet, still MORE space is taken up, and you only have 1.2GB free?
Get CCleaner, clean out temp files, both user and system.
Open Explorer.exe, right-click on C-colon, select Properties, click Disk Cleanup button, when that appears, click "System Disk Cleanup", and see if perhaps, you have an "old Windows" to clean up (Windows.old on your C-colon drive), and look at the other options for cleanup. There's an option for cleaning up "Windows Update Files", I DO NOT recommend checking that one off to clean up, because it can take... hours! The other stuff should clean up in under a few minutes on an SSD.
Also, check out "VSS Shadow Copies" / "VSS Shadow Copy Service", and VSSadmin.exe. Look it up on the web, I'm not super-familiar, but "shadow copies" can take up space on the disk, without appearing in the filesystem.
Consider using TreeSize, or WinDirSize, to check directory and free space size.
Also, read on the web how to delete / reset "Windows Indexing Service", if / when it gets "out of control" and starts "eating space", as it can do.
But honestly, a 128GB SSD these days is kind of too tight now. I put a 256GB-class SSD in all of my budget builds, except for extreme cases of browser-only boxes, then I might use one of my old 128GB-class SSDs.
(I remember my first SSDs, for both myself and my friend, 30GB OCZ SSDs, for Win7 64-bit. Left like 5GB free, at best. Had to manual trim down the PAGEFILE.SYS and remove the HIBERFIL.SYS to get everything to fit. Then Windows Updates came along, and bang! Need a bigger SSD.)
If you're going to buy one, just get one of the 1TB ones for $80 @ Newegg, honestly. Heck, you can even get 1TB M.2 NVMe SSDs, the Intel 660p, for around that price too, on sale. (Running a pair of those now in RAID-0 on this rig.)
Can you tell us how large your windows winsxs folder is? That's the hog that is always killing me.
I had to live on a Windows 7 machine with a 120GB drive that had winsxs cancer. I never solved the problem, I was due for a new PC so I just limped it along. It was hosed though, Windows update didn't even have enough space to run.
I actually thought Windows10 "solved" this problem by basically doing in place installs with the feature updates that started things over. Which is just papering over the problem really.
I'm saying, if Windows 10 was "Activated" on that hardware (same mobo, basically), then all you need to do is go to microsoft.com/windows10/download or something like that, and use the "Media Creation Tool", to make a bootable USB Win10 installer, and then use that to install Win10, and tell it that you don't have a key, and pick the edition that was previously installed, and it should activate Automatically. No need for keys entered, if Win10 was previously installed.Yeah, I'm thinking a fresh install bc the current install obvs has something wrong with it, inflating the windows file size ridiculously.
Here's the thing. I work at a university and got the current install from a Windows 10 'upgrade' that I bought for $10 or so (I did the 'install once, and then upgrade to use the. I'm currently taking classes, so I get another *full* copy of windows 10 for free. Can I install the full install (I'm thinking the install and then upgrade approach might be a problem) and use my old key, and save the new key for later use?

Edit: The only thing that I don't know, is if you had the "Educational" edition of Win10, if that is included in the MCT public version. There's a "Tech Bench" version too, you might have to track down and use that one to get a copy of the "Educational" edition installer.
