Your computer still works. Your operating system is what is slowing it down.
Many small businesses rely on older computers and specialized Windows programs they already purchased. Newer operating systems can make that hardware feel slow, while replacing the software may mean retraining, data migration, or a new monthly bill.
Proton OS offers another way forward. Its lightweight Linux foundation can extend the useful life of compatible PCs, while included Windows compatibility tools may preserve access to the applications your business still needs.
