Increased Spawnicon loading time?

I recently uninstalled GMod after a continuous 3 years of playing, only to reinstall about a week ago. I used to have my spawnicons load almost instantly, and I’d rarely have to worry about it slowing down anything. However, since my reinstall, each icon takes about 15 seconds to load, and causes my Gmod to freeze in windowed.

SOme things to note:
I recently upgraded to Windows 10.
I have a Dell Inspiron 15R with 2nd gen I5 processor, 8 gigs of RAM, 1TB HDD and Intel HD 4000 graphics (I often complain on here about lack of dynamic shadows).

Has anyone else had this problem?

Since you uninstalled your game, all your pregenerated spawnicons were also uninstalled.
The spawnicon generation process is one time ( per each model ), it is normal for the generation process to be slow.

Well, I meant that there was a point when my spawnicons weren’t taking as long to load the first time around, which is why I was surprised it was taking that long.
