Windows 10: Windows 10 acting weird after clean install on SSD

Hi, I recently reinstalled Windows 10 on my SSD and i'm starting to wish i would've never done that - it caused a bunch of problems for me, one of which is the following: i can't install any games from the Xbox app on my external drive a WD_Black P10 Game Drive, but i could before installing Windows on my SSD, that's the weird part.
If i want to install games on my external drive, the Xbox app requires me to format it, but with the amount of things i have on it and the fact that it worked perfectly before this is just NOT happening.
The bigger problem this reinstallation caused is that now i need an administrator permission for... basically everything. It doesn't make any sense because i am the only user of my PC, therefore i'm the administrator, i don't get why everything changed regarding this.

My old Windows is still on my regular HDD, could that be the reason ?? Some friends recommended me to format my HDD as well, but that will be the same answer as for my external drive, this just can't happen - i have waaay too many things on my HDD including lots of files that i ignore the purpose of, i wouldn't want to accidentally delete any sensitive file such as saves that i haven't moved etc.
I know that i might be a bit vague and that blocking some solutions is not helping at all but i just don't want to waste more time on this, I mean all i did was installing windows on another drive, there shouldn't be any stupid problem like this.


Thanks in advance for any reply.

Is it time for Windows 10 already?

Here's a good step by step guide on doing a fresh install.

How to clean install Windows 10 from a USB drive - Software - Feature - HEXUS.net

 

Win 10 clean install question

This is what I would do:

• Shrink the hard drive partition until it's small enough to fit on the SSD.
• Clone the Windows 8.1 setup to the SSD.
• Boot off the SSD and make sure that Windows 8.1 is happy (i.e., no complaints about activation).
• Upgrade to Windows 10 on the SSD.

This way, you know that Windows 8.1 has a valid setup on the SSD before doing anything else. Plus, the Windows 10 upgrade will be processed much faster on the SSD. Finally, you still have the hard drive setup to fall back to if anything goes wrong.

 

Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.
